The adjustable thermal-magnetic trip unit covers 150 A to 1 200 A, so you set the actual protection point to match the downstream load, not the breaker frame. Interrupting capacity climbs with the voltage you're clearing: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V.
Auxiliary hardware onboard
Also includes an undervoltage release (UVR). That means you get remote status and shunt-trip capability without buying add-on modules — just wire the UVR coil and the alarm contacts into your control circuit. The basic switch supplied is order code 3VA20106HL320AA0.
Trip indicator is present, voltage trigger is not — the UVR handles undervoltage, but there's no separate voltage-trip coil. No ground-fault monitoring version on this order code, so if you need GF protection you step to a different suffix.
