The Schneider C120 4P 30mA is a 4-pole residual current circuit breaker (RCCB) from Schneider Electric's C120 series. This device is designed to provide protection against earth leakage currents, preventing electric shocks and reducing the risk of fire caused by faulty wiring or equipment
Specifications:
Type: Residual Current Circuit Breaker (RCCB)
Poles: 4P (4 poles) – Suitable for three-phase systems with a neutral
Rated Current: Typically available in various ratings (e.g., 20A, 25A, 32A, etc.), depending on the application
Rated Voltage: 400V (typically for three-phase systems)
Rated Frequency: 50/60 Hz
Residual Current Sensitivity: 30mA (trips when a leakage current exceeds 30 milliamps)
Breaking Capacity: 10 kA (for short-circuit protection and disconnection under fault conditions)
Protection Features:
Earth Leakage Protection: Provides protection against earth leakage currents, which can occur due to faulty equipment or wiring.
Overload and Short-Circuit Protection: The device also ensures protection against overload and short circuit faults in the circuit.
