Mitsubishi BVW-T-4P-63A-30MA 4-Pole 63A 30mA Circuit Breaker

The Mitsubishi BVW-T-4P-63A-30MA (BVW-T-4P-63A-30MA) is a four-pole industrial circuit breaker designed for electrical distribution systems, equipment protection, and personnel safety against earth leakage faults. Engineered by Mitsubishi Electric as part of the BVW-T series, this protective switching device provides reliable circuit interruption and fault detection in commercial and industrial electrical panels. The BVW-T-4P-63A-30MA is rated for a continuous operating current of 63 A across 4 poles, with a rated residual operating current sensitivity of 30 mA. This 30 mA sensitivity allows rapid disconnection upon detection of residual leakage currents, helping mitigate electrical shock hazards and reduce fire risk resulting from insulation breakdown or wiring degradation. Built for standard modular enclosure and control cabinet mounting, the four-pole configuration accommodates three-phase electrical circuits with neutral connections. Typical applications include motor control centers, machinery power distribution, facility switchboards, and automation system power feeds requiring robust overcurrent and earth leakage management. The unit serves as an essential electrical component for maintenance, repair, and operational integrity across diverse manufacturing and industrial installations.
