CHINT NL210 Residual Current Operated Circuit Breaker

CHINT NL210 Residual Current Operated Circuit Breaker,

without over-current protection (RCCB) is designe for protection against earth fault currents and fire hazards in residential,
commercial, and industrial installations. As a Type B RCCB, it detects AC, pulsating DC,
and smooth DC residual currents up to 1000Hz, ensuring maximum safety for modern electrical systems.
Compliant with IEC/EN 62423 and IEC/EN 61008-1, the NL210 provides instantaneous tripping,
sensitivity options of 30mA–300mA, and a 10kA short-circuit rating, ensuring dependable protection without over-current functionality.
