Schneider Electric Switch

This is  Schneider Electric C120H 3-pole miniature circuit breaker (MCB), a critical protective device for low-voltage electrical systems.

Function: Provides overcurrent and short-circuit protection for three-phase electrical circuits. The "C" curve rating is designed for general-purpose loads, tripping at 5–10 times the rated current to balance sensitivity and stability.

Structure: A 3-pole modular design with a white thermoplastic housing, green identification strip, and black toggle switches marked "O-OFF". It features screw terminals for secure wiring and a rated current of 80A (model C120H C 80, part number GB10963.1).

Performance: High breaking capacity (up to 10kA) and compliance with IEC/GB standards, ensuring reliable protection for industrial and commercial electrical installations.

Application: Widely used in distribution boards, industrial machinery, and commercial buildings to protect motors, lighting systems, and other three-phase electrical equipment from overload and fault currents.
