It is a 3-pole unit rated 25 A at 40 °C, with a maximum breaking capacity of 75.6 kA at 240 V AC. The insulation voltage is rated 800 V, so it handles 480Y/277 V and 600 V panel feeds without issue.
Breaking capacity across voltages
This MCCB delivers 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 500 V and 690 V. That means it can clear high-fault currents on the secondary side of a 150 kVA transformer, but at 480 V the available fault current needs to stay under 32 kA — typical for most industrial panelboards. The 7.5 kA at 690 V covers 690 V drives or mining gear.
Rated 25 A continuous from 40 °C up to 50 °C. At 55 °C it derates to 24 A, and at 70 °C it holds 23 A. Ambient operating range is -25 °C to 70 °C; storage from -40 °C to 80 °C. Maximum power loss is 8.5 W.
Auxiliary and release configuration
The shunt trip allows remote tripping from a PLC or E-stop circuit — common for safety isolation in conveyor or HVAC systems.
The 3VA1025-3ED32-0JH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 76.2 mm width (3 inches) is a standard 3-pole MCCB footprint — fits existing busbar and enclosure cutouts without modification. The depth of 70 mm (2.76 in) leaves room for rear-access wiring in a 200 mm deep enclosure.
