The 3-pole construction handles three-phase feeders, and the integrated undervoltage release (UVR) drops the breaker if control voltage is lost, which is standard for emergency-stop or safety-shutdown circuits where loss of coil power must open the main contacts. 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 both 500 V and 690 V. That steep drop above 440 V means it is best suited for 240 V to 415 V distribution — at 690 V the 7.5 kA rating limits its use to low-fault-current subpanels or transformer-fed loads. ## Auxiliary contacts and trip indication That means you get remote status of the main contacts (open/closed) plus a separate signal for fault tripping — useful for PLC-based monitoring or annunciator panels. The undervoltage release is factory-fitted, so no field assembly needed.","metaTitle":"Siemens 3VA1063-3ED32-0CH0 SENTRON MCCB, 63 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1063-3ED32-0CH0 molded case circuit breaker, 63 A rated at 40 °C, 3-pole, line protection.
