The SENTRON 3VA2063-5JQ32-0HH0 is a 3-pole molded case circuit breaker (MCCB) rated for a continuous current of 63 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling. The adjustable thermal-magnetic trip unit covers a 95 A minimum to 756 A maximum setting range, so it can be tuned to protect a feeder or a large motor branch without swapping the breaker frame. Breaking capacity hits 187 kA at 240 V AC and still delivers 121 kA at 415/440 V, dropping to 75.6 kA at 500 V and 3 kA at 690 V.
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard SENTRON 3VA frame footprint that fits the same DIN-rail or screw-mount pattern as other 3VA2 breakers. The breaker includes a communication function, so it can integrate with a bus system for remote monitoring or trip-event logging.
