DABL-63 6kA 10kA Electronic Residual Current Device RCBO Circuit Breaker
Introduction
The DABL-63 6kA 10kA electronic 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.
