Summary
CJRO2-40 Residual Current Circuit Breaker with Overload Protection (RCBO) ensures high-level electrical safety for residential, commercial, and industrial applications. Designed to protect against leakage currents up to 30mA, as well as overloads and short circuits, this RCBO automatically disconnects the circuit upon fault detection, safeguarding both people and equipment. Featuring AC and A type options, it supports rated currents of 6A to 32A, leakage protection of 30mA, 100mA, and 300mA, and operates at 230VAC, 50/60Hz. Compliant with IEC61009-1/EN61009-1 standards, it offers reliable isolation, over-voltage protection, and enhanced circuit stability, making it ideal for modern electrical distribution systems.More
