The Schneider C120H C80 4P is a 4-pole circuit breaker from the Schneider Electric C120 series. It is designed for overload and short-circuit protection in electrical installations, particularly in industrial, commercial, and residential environments.
Specifications:
Type: Miniature Circuit Breaker (MCB)
Number of Poles: 4P (4 poles) – Suitable for three-phase systems with neutral conductor
Current Rating: 80A
Frame Size: C120H (indicating the frame size and current rating for this model)
Rated Voltage: Typically 400V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Type C (C80): The breaker trips when the current exceeds 5-10 times the rated current. This characteristic is suitable for circuits with moderate inrush currents such as motors and transformers, allowing brief current surges without tripping.
Breaking Capacity: Typically 10 kA at 400V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: Automatically disconnects the circuit if the current exceeds the rated value for an extended period, preventing overheating and damage to cables and equipment.
Short-Circuit Protection: Provides instantaneous disconnection when a short circuit occurs, limiting damage to the circuit and preventing fire hazards.
Manual Reset: After a fault condition, the breaker can be manually reset once the cause of the fault is resolved.
Compliance: Complies with IEC 60898-1 for low-voltage circuit protection.
