Rules for DC circuit-breakers1 Scope In addition to the general requirements of IEC 600772, this part of IEC 60077 gives the rules for circuit breakers, the main contacts of which are connected to DC power and or auxiliary circuits. The nominal voltage of these circuits does not exceed 3 000 V DC according to IEC 60850. This part of IEC 60077, together with IEC 600772, states specifically: a) the characteristics of the circuit breakers; b) the service conditions with which
