ELECTROMAGNETIC AC TYPE RCCB 2P

An electromagnetic AC type RCCB (Residual Current Circuit Breaker) with 2P refers to a specific type of two-pole RCCB used in electrical systems to protect against electric shocks and electrical faults. Here is a description of its features and functioning:

1. Residual Current Sensing: The RCCB continuously monitors the flow of electrical current in a circuit, specifically detecting any imbalance between the current flowing into the circuit and the current returning from it. It is designed to provide protection against electrical leakage or faults.
2. Trip Sensitivity: The RCCB is set to trip and interrupt the circuit if it detects a residual current above a certain threshold. The sensitivity is typically measured in milliamperes (mA) and can be adjusted, although common sensitivity settings are 30mA or 300mA. When the RCCB detects a residual current exceeding the set threshold, it will trip and cut off the power supply.
