Application

SM1-PV dc circuit breaker is designed to provide overcurrent protection within appliances or electrical equipment, where a branch circuit protection is already provided or not required. Devices are designed for direct current (DC) control circuit applications.  SM1-PV 3P DC750V 4P DC1000V specialized in Moulded Case Circuit Breaker dc circuit breaker is widely used in solar power system.

Specifications

Wiring diagram

■ Protection and Isolation wiring
■ The load should be ≤ DC1000V
The connection considered for onetwork in which the middle point of the supply source is earthed In this case the breaker protects and isolates the load
