Wholesale VL17-63 RCD RCBO RCCB 4P Circuit Breaker - 63A 415V AC Residual Current Device

The VL17-63 series 4P RCCB (Residual Current Circuit Breaker) is designed for effective protection against earth leakage currents in electrical installations. This industrial-grade circuit breaker operates at 50Hz with a rated voltage of 415V for 4-pole configurations and offers current ratings from 16A to 63A.

This residual current device provides crucial protection against electric shock hazards by detecting leakage currents as low as 30mA (0.03A). The breaker automatically disconnects the circuit when leakage exceeds the preset threshold, preventing potential electrical accidents and equipment damage.

Key applications include industrial plants, commercial buildings, high-rise structures, and residential complexes where reliable earth leakage protection is essential. The device complies with international safety standard IEC/EN 61008-1, ensuring high performance and reliability.

The VL17-63 features a robust design with 6000A short circuit capacity and can withstand impulse voltages up to 4000V. Its fixed mounting design and IP20 protection level make it suitable for standard electrical panel installations.

Available with different sensitivity options (0.03A, 0.1A, 0.3A), this RCCB can be customized to meet specific project requirements. The device supports both AC and A type operation for comprehensive protection against various types of residual currents.
