Integrator's spec recap — 3VA1032-3ED36-0JH0
Interrupting capacity reaches 75.6 kA at 240 V and 52.5 kA at 415 V — sufficient for high-fault points in industrial distribution panels where the upstream transformer or generator can deliver those levels.
The 32 A rating holds flat from 40 °C through 50 °C, then derates to 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. If the panel ambient inside the enclosure runs above 50 °C, the continuous load must be backed off accordingly — a 28 A continuous load at 70 °C still leaves margin, but a 32 A load at 55 °C would nuisance-trip on a warm day. Interrupting capacity at 440 V drops to 32 kA and at 690 V to 7.5 kA. For a 480 V wye service (277/480 V) the 440 V figure governs; verify the available fault current at the point of installation does not exceed 32 kA. At 690 V the breaker is still usable but only for systems with low prospective fault current — typically a step-down transformer secondary or a small generator. The integrated shunt trip (STL) release is specified as 3VA9688-0BL32 — order that separately if remote tripping is needed. No undervoltage release is present, so the breaker holds closed on loss of control power unless the shunt trip is wired to a supervision relay.
Deployment context — panel and enclosure
The 3VA1032-3ED36-0JH0 measures 76.2 mm wide, 130 mm high, and 70 mm deep, fitting the standard 3-pole MCCB footprint on a DIN rail or direct panel mount. The latching endurance of 15 000 cycles covers frequent switching in process lines but not continuous-duty motor starting; for motor circuits, pair this MCCB with a contactor rated for the load.
