Massarent RCCB DP-040-100 40A 100mA Double Pole Residual Current Circuit Breaker (RCCB)

Long Description

The RCCB DP-040-100 40A 100mA Double Pole Residual Current Circuit Breaker is an electrical safety device designed to detect leakage currents caused by insulation failure or earth faults and automatically disconnect the power supply to prevent electrical hazards.

With a 40A rated current, 100mA sensitivity, and Double Pole (DP) configuration, the RCCB disconnects both phase and neutral conductors when leakage current exceeds the defined threshold. The 100mA sensitivity level is generally used for fire protection and equipment safety applications in distribution systems.

Built using flame-retardant thermoplastic housing and precision internal sensing mechanisms, the RCCB ensures reliable operation, stable performance, and long service life. Its DIN rail mounting design allows easy installation in distribution boards, switchgear panels, and electrical control systems.

This device is suitable for a wide range of applications including residential complexes, commercial buildings, industrial panels, and infrastructure projects requiring dependable earth leakage protection.
