The Schneider C120H 3P 63A is a 3-pole miniature circuit breaker (MCB) from the C120H series, designed for overload and short-circuit protection in three-phase electrical systems.
Specifications:
Type: Miniature Circuit Breaker (MCB)
Number of Poles: 3P (3 poles) – Suitable for three-phase systems
Current Rating: 63A
Frame Size: C120H (compact and reliable protection in a small form factor)
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Thermal Protection: Provides overload protection by disconnecting the circuit if the current exceeds the rated value for an extended period, preventing damage to wiring and connected devices.
Magnetic Protection: Provides instantaneous disconnection in the event of a short circuit, minimizing damage to the electrical system and preventing potential hazards.
Adjustable Thermal Settings: The thermal protection settings can be adjusted, offering flexibility for different types of loads (e.g., motors, lighting circuits).
Breaking Capacity: Typically 6 kA at 415V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: Trips the breaker when the circuit experiences sustained overloads, protecting the system from overheating and fire hazards.
Short-Circuit Protection: Provides instantaneous disconnection during short circuits, ensuring minimal damage to the system.
Manual Reset: After tripping, the breaker can be manually reset once the fault has been cleared and it is safe to restore normal operation.
Compliance: Complies with IEC 60898 for circuit protection in low-voltage systems.
