Massarent RCCB DP-063-300 63A 300mA Double Pole Residual Current Circuit Breaker (RCCB)

Long Description

The RCCB DP-063-300 63A 300mA Double Pole Residual Current Circuit Breaker is a safety device that continuously monitors leakage current in an electrical circuit and automatically disconnects the supply when leakage exceeds safe limits.

With a 63A rated current, 300mA sensitivity, and Double Pole (DP) configuration, the RCCB disconnects both phase and neutral conductors upon detection of residual current imbalance. The 300mA sensitivity level is primarily intended for fire protection and insulation fault monitoring, helping prevent overheating and electrical fire risks in distribution systems.

Built with flame-retardant thermoplastic housing and precision tripping mechanisms, the device ensures reliable operation, stable performance, and long service life. Its DIN rail mounting system allows easy installation in distribution boards, switchgear panels, MCC panels, and electrical control systems.

The RCCB DP-063-300 is suitable for industrial facilities, commercial complexes, infrastructure projects, and heavy electrical installations where system-level earth leakage protection is required.
