That 3.7 kA figure at 690 V is the hard limit — if your motor circuit runs at 690 V and the available fault current exceeds that, this breaker is not the right fit. The adjustable thermal-magnetic trip range spans 189 A minimum to 945 A maximum, which covers motor FLA from roughly 75 A to 380 A depending on the tap setting. ## Starter protection and undervoltage release The starter-protection design (design code 7MS32) integrates an undervoltage release (UVR) that drops the breaker if control voltage falls below the dropout threshold — standard for motor control centers where a voltage sag should trip the starter rather than let it re-accelerate uncontrolled. The UVR is factory-fitted; no field kit required. Two HQ auxiliary switches are included for status feedback to the PLC or HOA station. Maximum power loss is 6.5 W, negligible for enclosure heat-load calculations.","metaTitle":"Siemens 3VA2163-7MS32-0CC0 SENTRON MCCB, 63 A, 3-Pole, Start","metaDescription":"Siemens SENTRON 3VA2163-7MS32-0CC0 molded case circuit breaker, 63 A continuous at 40-70°C, 3-pole, 330 kA at 240 V.
