KNM1-3P series moulded circuit breaker
The circuit breaker has a rated insulation voltage of 800v and applies at the distribution circuit of Ac 50/60Hz,rated operating voltage up to 690V and rated operating current from 6a up to 800a to distribute the electric power and protect the line and prevent the pover equipment from overload and short circuit and other fault.Meanwhile,it could act for the low frequenc of starting and overload and short circuit protection.
The circuit breaker could be of vertical installation or transversal installation.
This product conforms to the requirement of IEC60947-2 & GB14048.2 standards
