WNB1-63 2P MCB 6kA Double Pole Circuit Breaker
Buy Westhomes WNB1-63 2P MCB. True double-pole protection for 400V circuits. 6kA breaking capacity. B/C/D trip curves. Ideal for AC units and motors.
The Westhomes WNB1-63 2P MCB provides comprehensive protection by controlling and safeguarding both the phase and neutral conductors. Unlike 1P+N designs, this true double-pole breaker ensures that both poles are protected against overcurrent and are positively isolated when switched off, making it the safest choice for critical circuits.
Key Features:
Dual Conductor Protection: Offers thermal-magnetic protection on both poles, ensuring complete safety for the connected circuit.
High Interruption Rating: Confident 6kA breaking capacity handles high fault currents effectively.
Versatile Trip Curves: Choose between B, C, or D curves to match specific load types, such as motor starting (D curve) or general power (C curve).
Wide Voltage Compatibility: Suitable for both 230V (split-phase) and 400V applications.
Robust Build: Housed in a durable flame-retardant casing with IP20 finger-safe terminals, designed for standard DIN rail mounting.
Applications
Dedicated appliance circuits (A/C, water heaters), heat pumps, small motors, and applications requiring complete circuit isolation.
