Residual Current Circuit Breaker (RCCB / ELCB) — Double Pole

Keep your home and equipment safe from dangerous earth‑leak faults with the H‑RCCB‑ELCB‑DP — a compact, high‑safety double‑pole residual current breaker designed to detect leakage currents and cut power before harm occurs.

Quick takeaway

The double‑pole RCCB instantly disconnects both live and neutral on detecting imbalance between phases, preventing electric shock, fire risk from earth leakage, and damage to sensitive appliances. This listing shows 25A models with 30mA or 100mA trip sensitivity options — choose lower mA for personal protection (sockets, bathrooms) and higher mA for selective appliance protection.

What it does

RCCBs monitor current flow in live and neutral conductors. If a difference (residual current) appears — indicating current is leaking to earth — the device trips immediately, isolating the circuit and reducing the risk of electrocution or insulation‑fault fires. The double‑pole design ensures both conductors are disconnected for maximum safety.

Key features

• Double‑pole protection — isolates both live and neutral together for safer disconnection.
• Available sensitivities — 30mA / 100mA — 30mA for human protection, 100mA for equipment/earth‑fault selectivity.
• Rated example — 25A (check the product page for available ampere ratings).
• Fast, reliable trip action — reduces shock and fire risk from leakage currents.
• Compact wall/DB mount form — fits consumer units and distribution boards for neat installation.
• Brand-grade construction — built for consistent operation in residential and light‑commercial environments.

Why this RCCB stands out

• Life‑saving protection — a 30mA RCCB cuts fault current fast enough to prevent serious electric shock.
• Reduced fire risk — detects small leakages that ordinary MCBs won’t catch.
• Flexible selection — sensitivity options let you match protection to the circuit (personal vs. device).
• Simple upgrade — an easy way to bring older installations up to safer standards.
• Clear peace of mind — reliable residual‑current monitoring for kitchens, bathrooms, outdoor sockets, and workshops.

Typical applications

• Socket circuits and general household protection
• Bathroom and kitchen outlets (where water increases shock risk)
• Outdoor and garden power points
• Backup generator and inverter output protection
• Workshops, garages, and light commercial circuits where leakage protection is required

Installation & note

For correct selection and safe installation, confirm the required ampere rating and trip sensitivity for each circuit — use 30mA for personal protection and 100mA where nuisance trips are a concern but some earth‑fault protection is still needed. Have a qualified electrician install and test the RCCB and, if available, consult the product datasheet for mounting and wiring details.

Ready to protect people and property? Choose the H‑RCCB‑ELCB‑DP for fast, reliable earth‑leak detection, double‑pole isolation, and everyday peace of mind — add to cart to upgrade safety in minutes.

01 — ABOUT ALPHAEMART & OUR PRODUCTS

Q  What is ALPHAEMART — and why should I buy from you instead of a local shop?

ALPHAEMART is Bangladesh’s dedicated destination for premium ceiling fans and modern home electronics — ceiling fans, air coolers, and water heaters — engineered for real Bangladeshi conditions.

Unlike general electronics shops that stock dozens of unrelated brands, every product we carry is hand-picked for build quality, energy efficiency, and long-term reliability. We back that with a Money Guarantee, flexible payment options, and real customer support — before and after your purchase.

4.7 stars from 100% verified buyers. That’s not marketing — that’s people who already live with our fans.

Q  Are these genuine products, or cheap imported imitations?

Every product sold on alphaemart.shop is 100% genuine. We do not source grey-market or low-grade replicas.

Our ALPHA fan series — KDK 8-Blade Designer, Cleo 4-Blade, and Kuhl BLDC — are manufactured to strict quality standards. What you see on the product page is exactly what arrives at your door. Sealed. Intact. Ready to install.

Still unsure? Read our customer reviews or call us directly at +8801323725272 — we’re happy to walk you through any product.

Q  What products do you sell?

Our current catalogue includes three core categories:

Ceiling Fans: ALPHA KDK 8-Blade Designer Fan, ALPHA Cleo 4-Blade Fan, ALPHA Kuhl BLDC 3-Blade Energy-Saving Fan. Available in sizes 48”, 50”, 56”, 62”, and 72”. Finishes include White, Darkwood, Light Wood, White Gold, and Chrome.

Air Coolers: Energy-efficient models for fast, effective cooling.

Water Heaters: Safe, reliable, built for daily household use.

We regularly add new products. Visit alphaemart.shop to see what’s currently available and on sale.

Q  What’s the difference between a BLDC fan and a regular fan? Is it actually worth the extra cost?

Yes — especially in Bangladesh where electricity bills are a real concern.

A standard fan motor (AC induction) consumes 70–80 watts per hour. Our ALPHA Kuhl BLDC motor runs on just 28–32 watts — that’s up to 65% less energy for the exact same airflow.

Over a single year of normal use (8 hours/day), a BLDC fan can save you Tk 2,000–3,500 in electricity costs alone. The fan pays for its price difference within 1–2 years — and then continues saving you money every year after that.

BLDC fans are also quieter, run cooler, and last significantly longer than conventional motors.

Q  Which fan size is right for my room?

Here’s a simple guide based on room size:

48” – Small rooms up to 100 sq ft (bedroom, study)

50”–56” – Medium rooms 100–200 sq ft (living room, master bedroom)

62”–72” – Large rooms 200–400 sq ft (open-plan living areas, dining + lounge combined)

If you’re unsure, message us on +8801323725272 with your room dimensions and we’ll recommend the right model for you.

Q  Do your fans come with a remote control and a built-in light?

Many of our models do, yes. The ALPHA KDK 8-Blade Designer Fan and selected variants of the Cleo and Kuhl series include remote control and integrated LED lighting.

Product-specific features are listed clearly on each product page. If a feature matters to you — remote, light, specific colour finish — check the product description or ask our team before ordering.

02 — PRICING & PAYMENT

Q  Your fans are priced higher than what I see in local markets. Why?

Because they’re not the same product.

Cheaper fans use conventional AC motors with lower-grade windings, plastic internals, and no safety certifications. They feel affordable until the motor burns out in 18 months, the blades wobble, or your electricity bill quietly doubles.

ALPHAEMART fans use BLDC motors, precision-balanced blades, and finishes that hold up in Bangladesh’s climate. They’re built to run 8–12 hours a day for years without issue.

When you factor in electricity savings and replacement costs, an ALPHA fan is typically the cheaper choice over a 5-year period. Buy once. Buy right.

Q  What payment methods do you accept?

We accept multiple payment options at checkout including Visa, Master and Bkash.

We also offer flexible payment arrangements. If you need to discuss payment options for your order, contact us at +8801323725272 before placing your order and we’ll work something out.

Q  Are the prices on the website final? Any hidden fees or charges?

What you see is what you pay. There are no hidden fees added after checkout.

Shipping costs (if applicable to your location) are calculated transparently at checkout based on your delivery address — before you confirm payment. You will always see the full total before you commit to anything.

Current sale prices are live on the site. The ALPHA KDK 8-Blade, for example, is currently Tk 23,500 (down from Tk 28,500) — a saving of Tk 5,000.

03 — ORDERING & DELIVERY
