The Schneider iC65N 3P 40A is a 3-pole miniature circuit breaker (MCB) from the iC65N 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 with neutral
Current Rating: 40A
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Thermal Protection: Protects against overload conditions by disconnecting the circuit when the current exceeds the rated value for an extended period. This prevents overheating and potential fire hazards.
Magnetic Protection: Provides instantaneous protection during a short-circuit by disconnecting the circuit quickly to avoid damage from high fault currents.
C Curve: The iC65N series features a C-curve, which means the breaker trips between 5 to 10 times the rated current for short-circuits, offering a balance between sensitivity and robustness.
Breaking Capacity: Typically 6 kA at 415V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: Ensures that circuits are protected from long-duration overloads, preventing damage to the wiring and appliances.
Short-Circuit Protection: Disconnects the circuit instantaneously during a short-circuit, preventing extensive damage to the system.
Manual Reset: After tripping, the breaker can be manually reset, making it easy to restore normal operation once the fault is cleared.
