The overcurrent release is an ETU310M electronic trip unit, and an undervoltage release (UVR) is integrated. The 63 A rating holds flat from 40 °C through 50 °C; derating begins at 55 °C (60.48 A) and drops to 56.7 A at 70 °C. For a panel that runs warm — say a motor control center at 55 °C ambient — the breaker still carries 60.48 A, so a 63 A feeder or motor circuit is safe. The 330 kA interrupting capacity at 240 V is the headline number, but the 242 kA at 415 V is the one that governs most 400 V-class industrial distribution. ## Panel integration and dimensions The 105 mm width fits a 3-pole MCCB footprint; adjacent breakers or contactors in a multi-unit lineup need that pitch respected. ## Environmental and endurance limits The latching endurance is rated at 20,000 operations — this is the mechanical life under no-load conditions, not the electrical endurance under fault.","metaTitle":"Siemens 3VA2163-7MS32-0CH0 MCCB, 63 A, 330 kA at 240 V","metaDescription":"Siemens SENTRON 3VA2163-7MS32-0CH0 molded case circuit breaker, 63 A rated, 330 kA interrupting at 240 V.
