Its interrupting capacity hits 242 kA at 240 V, stepping down to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. That 242 kA figure at 240 V means it can safely clear a fault with extremely high available short-circuit current — typical for transformer-secondaries or large motor control centers — without the breaker rupturing or cascading failure upstream. ## What the Ratings Mean for Fit The 63 A rating is the continuous current the breaker carries without tripping — matched to a 63 A feeder or load circuit. The 242 kA interrupting capacity at 240 V is the maximum fault current it can safely interrupt; if your available fault current at the panel exceeds that, you need a current-limiting upstream device or a higher-rated frame. The 800 V rated insulation voltage covers 480 V and 600 V class systems with margin. The 86 mm depth and 105 mm width fit standard MCCB panel footprints — verify the mounting pattern against your existing bus or base plate. ## Integration and Auxiliary Options The breaker ships with a factory-fitted auxiliary switch block: 2 auxiliary switches plus 1 trip alarm switch (HP design). That gives you two N.O./N.C. contacts for status feedback and a dedicated alarm contact that changes state only on a trip event — useful for remote annunciation or PLC input. No undervoltage release, no ground-fault monitoring, and no communication module are included on this variant. The supplied basic switch is order code 3VA20636HN320AA0 — that's the core switching mechanism inside the molded case. Power loss is 5.4 W maximum, negligible for panel thermal budgeting.","metaTitle":"Siemens 3VA2063-6HN32-0AJ0 SENTRON MCCB, 63 A, 242 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-6HN32-0AJ0 molded case circuit breaker, 63 A continuous, 242 kA breaking at 240 V. 3-pole line protection.
