Custom OEM ODM WSB1L MCB Circuit Breaker with CE CB CCC Certification for Power Distribution

The WSB1L series Residual Current Circuit Breakers (RCCB) are designed for electrical distribution systems requiring reliable protection against leakage currents, overloads and short circuits. These compact breakers feature advanced tripping mechanisms and durable flame-retardant housings for maximum safety.

With multiple pole configurations available (1P+N and 3P+N), the WSB1L breakers are suitable for both residential and commercial applications including office buildings, residential complexes and industrial facilities. The modular design allows for easy DIN rail mounting in standard electrical panels.

These circuit breakers provide sensitive leakage current protection with adjustable trip settings from 10mA to 300mA, making them ideal for personnel protection applications. The fast-acting mechanism ensures quick disconnection when faults are detected.

The WSB1L series complies with international safety standards including IEC61008-1 and carries CE, CB and CCC certifications. The robust construction ensures reliable performance even in demanding electrical environments.
