Massarent RCCB FP-040-300 40A 300mA Four Pole Residual Current Circuit Breaker (RCCB)

Long Description

The RCCB FP-040-300 40A 300mA Four Pole RCCB is an electrical safety device engineered to continuously monitor leakage current in three-phase four-wire systems and automatically disconnect the supply when leakage exceeds safe limits.

With a 40A rated current, 300mA sensitivity, and Four Pole (FP) configuration, this RCCB disconnects all three phases along with the neutral conductor during fault conditions. The 300mA sensitivity level is primarily used for fire protection and insulation fault monitoring, helping reduce the risk of electrical fires caused by sustained leakage currents.

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, MCC panels, switchgear systems, and industrial electrical installations.

The RCCB FP-040-300 is widely used in environments where higher-level leakage protection is required for equipment safety and fire prevention.
