MCBs in Bangladesh: Ratings, Pole Options and Selection
Compare AKIJ Electricals miniature circuit breakers using the circuit specification prepared by your electrician. MCB selection involves more than an ampere value: the pole arrangement, rated voltage, tripping characteristic, breaking capacity and installation compatibility all need to match the design.
Planning Your MCBs Purchase
Prepare a circuit schedule before requesting MCBs. Record the exact device specification and quantity for each circuit, including any requirements for coordination with other protective devices. Do not replace a repeatedly tripping breaker with a higher-rated model without investigating the cause.
Explore single-pole, double-pole and triple-pole MCBs. For residual-current protection, review the separate RCCB category with the project electrician.
MCBs FAQs
Provide the specified pole count, current and voltage ratings, trip characteristic, breaking capacity and model reference. The electrician should confirm these against the circuit and installation requirements.
No. An MCB provides overcurrent protection; an RCCB detects residual current. The installation may require both functions in a coordinated arrangement specified by a qualified professional.
Do not increase the rating just to stop tripping. Have an electrician investigate the circuit, load and device condition and specify an appropriate remedy.
