It delivers 187 kA interrupting capacity at 240 V AC, dropping to 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That steep drop-off at 690 V means this breaker is sized for 400/480 V distribution panels where fault current stays under 121 kA; at 690 V it's limited to low-fault sub-distribution. At 415 V, the 121 kA breaking capacity (Icu) puts this MCCB in the high-range class for a 63 A frame — enough to handle most transformer-fed secondary distribution without cascading. The minimum rated current is 95 A (likely the adjustable thermal-magnetic range floor), with a maximum of 756 A (the short-circuit release setting). For selectivity studies, the 187 kA at 240 V gives headroom on the low-voltage side of a 480/277 V panel; coordination curves with downstream 10 kA or 18 kA MCBs should hold without upstream trip. The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint for 63 A frames. ## Ground-fault and auxiliary features This variant includes summation-current ground-fault monitoring on the line conductor — it measures the vector sum of phase currents to detect leakage, not a dedicated neutral-ground sensor. The basic switch is a 3VA21635JQ320AA0 internal mechanism. No undervoltage release or trip indicator is fitted on this order code; those are separate accessory options.","metaTitle":"SENTRON 3VA2163-5JQ32-0AB0 MCCB, 63 A, 187 kA at 240 V","metaDescription":"SENTRON 3VA2163-5JQ32-0AB0 molded case circuit breaker, 63 A rated current, 187 kA breaking capacity at 240 V.
