Three poles, with a symmetrical breaking capacity of 187 kA at 240 V and 121 kA at 415 V, dropping to 75.6 kA at 500 V and 9 kA at 690 V. That 187 kA at 240 V is the headline number — it handles high available fault current on 240 V delta or 277/480 V wye services where the transformer is close.
Footprint: 138 mm wide, 248 mm tall, 110 mm deep. That 110 mm depth (4.33 in) clears most standard enclosures with room for the rear bus. The UVR is factory-installed; verify coil voltage against your control circuit before wiring. No ground-fault monitoring built in — that's an external add-on if needed. Maximum power loss of 66 W at rated load.
