The Schneider C120 3P D100A is a 3-pole circuit breaker from the Schneider C120 series, designed to provide overload and short-circuit protection in electrical circuits, particularly in three-phase systems
Specifications:
Type: Miniature Circuit Breaker (MCB)
Number of Poles: 3P (3 poles) – Suitable for three-phase systems
Current Rating: 100A
Frame Size: C120 (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 D: Trips between 10-20 times the rated current, making it suitable for circuits with moderate inrush currents (e.g., motor circuits and transformers).
Breaking Capacity: Typically 10 kA at 400V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: Automatically disconnects the circuit in case of prolonged overcurrent conditions, preventing overheating and damage to equipment and wiring.
Short-Circuit Protection: Provides instantaneous disconnection when a short circuit occurs, preventing further damage to electrical components.
Manual Reset: After a fault condition, the breaker can be manually reset once the cause is resolved.
Compliance: Complies with IEC 60898-1 for low-voltage circuit protection.
