The Schneider CVS 4P 400A is a 4-pole molded case circuit breaker (MCCB), part of the CVS series, designed to provide overload protection, short-circuit protection, and earth leakage protection in four-wire electrical systems (3 phases + neutral).
Specifications:
Type: Molded Case Circuit Breaker (MCCB) with Residual Current Protection (RCD)
Number of Poles: 4P (4 poles) – Suitable for three-phase systems with neutral
Current Rating: 400A
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Thermal Protection: Disconnects the circuit in the event of overload conditions, preventing overheating and damage to equipment or wiring.
Magnetic Protection: Provides instantaneous disconnection during short-circuit conditions, preventing damage from high fault currents.
Residual Current Protection (RCD): The breaker provides earth leakage protection, disconnecting the circuit if leakage currents exceed a predetermined threshold, ensuring safety against electric shocks.
Breaking Capacity: Typically 50 kA at 415V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: Disconnects the circuit in the event of sustained overload conditions to prevent overheating and damage.
Short-Circuit Protection: Provides instantaneous disconnection during short circuits, preventing damage to wiring and connected equipment.
Earth Leakage Protection: Disconnects the circuit when earth leakage exceeds a preset threshold, providing protection from electric shock hazards.
Manual Reset: The breaker can be manually reset after the fault condition is cleared, allowing the system to return to normal operation.
Compliance: Complies with IEC 60947-2 (low-voltage circuit protection) and IEC 61008 (residual current devices), ensuring it meets international safety standards.
