Its 3-pole construction and line-protection design make it a straight fit for feeder or main breaker duty in a 3-phase distribution panel. Breaking capacity is the headline: 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V.
Built-in accessories and wiring
The auxiliary switches provide status feedback for PLC or indicator lamps; the shunt trip allows remote tripping from an E-stop or safety relay. No undervoltage release is included — if you need UVR for machine safety circuits, that would be a separate order. The basic switch is order code 3VA2163-6HN36-0AA0, which means the breaker core is a standard line-protection unit; the -0JH0 suffix adds the auxiliary and shunt-trip options. Power loss is 4 W maximum — negligible for thermal coordination inside a sealed enclosure.
