DAB7N-40 Series DPN Miniature Circuit Breaker
Certifications
IEC60898GB10963
Description
DAB7N-40 series DPN miniature circuit breaker adopts 1P+N double-break structure, with two-pole insulation isolation. During synchronous operation, the N pole closes first and opens later, ensuring arc breaking capacity and circuit safety. Compliant with IEC60898 and GB10963 standards, rated current 40A, rated voltage 230V, with thermal-magnetic trip characteristics.
