MCB stands for Miniature Circuit Breaker. It is an electrical protection device widely used in residential, commercial, and industrial applications to protect electrical circuits and connected equipment from overcurrents and short circuits. MCBs are a type of circuit breaker designed to trip and interrupt the flow of electrical current when the current exceeds a certain predefined value, thus preventing damage to electrical devices and preventing potential hazards.
Key features and aspects of MCBs include:
- Standard Conformity: IS/IEC 60898-1:2002
- Rated Current (In): 0.5A-63A | Poles: SP, SP+N, DP, TP, TP+N, FP
- Tripping characteristic: B & C
- Rated Short circuit capacity: 10,000A
- Rated Voltage: 240/415-AC
- Rated frequency:50Hz
- Terminal Capacity 35sq.mm
- Protection class: IP20
An MCB, or Miniature Circuit Breaker, is an electrical protection device used to protect electrical circuits and connected equipment from overcurrents and short circuits. It is a type of circuit breaker that automatically trips and interrupts the flow of electrical current when the current exceeds a certain predefined value.
MCBs work based on thermal and magnetic trip mechanisms. When an excessive current flows through the MCB, the heat generated causes the bimetallic strip to bend, tripping the breaker. Additionally, a magnetic trip element responds to sudden short-circuit currents, causing rapid tripping to protect the circuit.
