That flat thermal curve simplifies panel design in warm enclosures; no need to upsize the frame for a 50 °C or 60 °C environment. Interrupting capacity is 187 kA at 240 V, 121 kA at 415 V and at 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. The adjustable thermal-magnetic trip range spans 95 A minimum to 756 A maximum, with an initial setting of 16 A. That wide adjustment band lets one frame cover multiple branch circuits, but the 63 A full-scale rating governs the continuous current limit — the trip range is the magnetic/instantaneous adjustment, not the continuous ampacity. Verify gland-plate clearance on the 86 mm depth; it fits most 200 mm deep enclosures but may require a spacer in shallow 150 mm boxes. The trip alarm switch provides a dedicated signal for the breaker's thermal-magnetic trip event, separate from the auxiliary position indicators. No undervoltage release is fitted. Communication function is present on this variant, per the designation. The basic switch assembly is order code 3VA20635JQ320AA0. Maximum power loss is 5.4 W at rated current.","metaTitle":"Siemens 3VA2063-5JQ32-0JL0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5JQ32-0JL0 molded case circuit breaker, 63 A, 3-pole, 187 kA at 240 V.
