Because of this, Breakers serve as essential devices across various electrical appliances and wiring, ensuring safety at all times by providing the necessary protection for every individual relying on them. In Bangladesh, for homes or even for industrial setups, it is important to utilize appropriate RCCB, MCCB, and MCB circuits due to frequent power fluctuations.

Circuit Breaker Types

 Miniature Circuit Breaker (MCB) 

Specifically meant for home use within the low-current range.

Features:

• Current range: 6A to 63A
• Trips for overloads & short circuits
• Compact size with a reasonable cost
• Place of usage: Residential homes, stores, and offices.

Molded Case Circuit Breaker (MCCB)

Industrial areas heavily use MCCB due to MCBs having a poor current handling range, It's ideal during high current usage.

Features:

• Current range: 125A to as required
• Adjustable trip options
• Thermal and magnetic safety
• Great endurance during high fault currents

Place of usage: Commercial buildings, electrical panels, and Factories.

MCCB Circuit Breaker Price in Bangladesh:

• 125A MCCB: Starting From ৳4,450
• 160A MCCB: Starting From ৳4,900
• 200A MCCB: Starting From ৳6,350

It can prevent electric shock by detecting leakage current.

Key Features:

Recommended requirements for blow box montage protection array:

• Tripping range at leakage 30mA/100mA
• Protection against electrocution
• Used with MCB only gives full protection
• Best used in: Homes, hospitals, and wet areas (bathrooms, kitchens).

How Do You Choose the Best Circuit Breaker?

Check current rating

• MCB: Light & Sockets (6A-32A)
• MCCB: Heavy machines (100A+)
• RCCB: A must in wet areas.

Consider breaking capacity

• 6kA: Ideally for homes
• 10kA-100kA: Required in industries
