Massarent RCCB FP-040-30-5 40A 30mA Four Pole Residual Current Circuit Breaker (RCCB)

Long Description

The RCCB FP-040-30-5 40A 30mA Four Pole RCCB is an advanced electrical safety device engineered to continuously monitor leakage current in three-phase four-wire systems and disconnect the supply instantly when unsafe conditions are detected.

With a 40A rated current, 30mA sensitivity, and Four Pole (FP) configuration, the RCCB simultaneously disconnects all three phases and the neutral conductor when earth leakage exceeds the safe threshold. The 30mA sensitivity level is widely used for personal protection, ensuring rapid disconnection to reduce the risk of electric shock.

Built with flame-retardant thermoplastic housing and precision tripping mechanisms, the device ensures high reliability, fast response, and long operational life. Its DIN rail mounting design allows easy installation in distribution boards, switchgear panels, and electrical control systems.

The RCCB FP-040-30-5 is suitable for modern electrical installations where complete four-wire protection and enhanced safety performance are required.
