Massarent RCCB DP-040-300 40A 300mA Double Pole Residual Current Circuit Breaker (RCCB)

Long Description

The RCCB DP-040-300 40A 300mA Double Pole Residual Current Circuit Breaker is an electrical safety device engineered to detect earth leakage currents and automatically disconnect the electrical supply when leakage exceeds the safe limit.

With a 40A rated current, 300mA sensitivity, and Double Pole (DP) configuration, this RCCB disconnects both phase and neutral conductors when a fault condition is detected. The 300mA sensitivity level is primarily used for fire protection and equipment safety, helping prevent overheating and electrical fires caused by sustained insulation leakage.

Manufactured using flame-retardant thermoplastic housing and precision internal tripping mechanisms, the device ensures stable performance, reliable operation, and long service life. Its DIN rail mounting system enables easy installation in distribution boards, switchgear panels, and control cabinets.

The RCCB DP-040-300 is ideal for systems requiring higher leakage thresholds for fire prevention and general electrical safety monitoring in industrial and commercial environments.
