Breaking capacity is the other headline: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. ## Panel fit and physical integration The footprint is 76.2 mm wide (3 in), 130 mm tall (5.12 in), and 70 mm deep (2.76 in). Three poles in a single compact block — no ganging required. Maximum power loss is 10.6 W. ## Auxiliary and release configuration The trip alarm switch gives a separate signal when the breaker trips on fault — useful for remote annunciation or a PLC input that triggers a shutdown sequence. The shunt trip lets you remotely open the breaker via a control voltage, which is common in emergency-stop circuits or fire-alarm interlocks. No undervoltage release on this build, so it won't drop out on a sag; that's a deliberate choice for processes that ride through dips. A voltage trigger indicator is present, and a mechanical trip indicator flags a fault locally. No communication function or ground-fault monitoring on this unit — it's a straight line-protection breaker with auxiliary signaling.","metaTitle":"Siemens 3VA1032-3ED32-0JH0 SENTRON MCCB, 32 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1032-3ED32-0JH0 molded case circuit breaker, 32 A rated at 40 °C, 3-pole, 70 mm depth.
