Tertiary circuit breakers up to 6 Ka
Tertiary circuit breakers up to 6 kA are compact overcurrent protection devices designed for low-fault-current applications, typically in final distribution circuits. These single-pole (1P) or double-pole (2P) units are rated for short-circuit capacities up to 6 kA per IEC 60898-1, with nominal currents ranging from 6 A to 63 A at 230/400 V AC. ...
