WR1L-63 4P 63A Three-Phase Residual Current Circuit Breaker
Protect 3-phase industrial systems with the WR1L-63 4P RCCB. 63A rating, 30-300mA adjustable leakage protection. Ideal for machinery & distribution boards.
The Westhomes WR1L-63 Series 4-Pole Residual Current Circuit Breaker (RCCB) is engineered to provide comprehensive protection against earth leakage currents in three-phase electrical systems. Designed for industrial environments, commercial buildings, and large-scale residential complexes, this 4P device ensures maximum safety for personnel and equipment by detecting and interrupting ground faults across all phases and neutral.
Key Features:
True 4-Pole Protection: Monitors and switches all three phases (L1, L2, L3) and the neutral conductor simultaneously, ensuring complete isolation and comprehensive protection for three-phase systems.
Flexible Sensitivity Ratings: Available in 30mA (personal protection), 100mA (fire protection), and 300mA (equipment protection) to meet diverse industrial and commercial safety requirements.
High Breaking Capacity: Rated at 6kA short-circuit withstand capacity, offering robust protection even in demanding industrial settings with high fault current potential.
Robust Construction: Built with high-quality materials to withstand vibration, heat, and electrical stress in demanding three-phase installations.
Protective Functions:
Three-Phase Earth Leakage Protection
Personnel & Equipment Safety
Fire Prevention in 3-Phase Circuits
Applications:
Industrial machinery and manufacturing equipment
Commercial Buildings
Large Residential Complexes
