Nova Dabf-63 3p+N 63A Electromagnetic RCBO

DABF-63 6kA 10kA Electromagnetic Residual Current Device RCBO Circuit Breaker

Introduction
The DABF-63 6kA 10kA electromagnetical residual current circuit breaker is designed by Dada engineers for stable operation, precise protection, short opening time, and a high breaking capacity index, all in one small device. The circuit breakers are also produced according to GB 10963 and IEC60898 standards.

The circuit breakers are commonly installed for the overload protection of contactors, relays, and other electrical equipment.

Main functions: short circuit protection, overload protection and isolation.
