Its interrupting capacity hits 187 kA at 240 VAC, 121 kA at 415 VAC, and 75.6 kA at 500 VAC, dropping to 3 kA at 690 VAC. The 63 A full-scale rating with a 16 A initial setting range (adjustable from 16 A to 63 A) gives you flexibility to tune the trip threshold to the actual load without swapping the breaker. The interrupting curve tells the real story: at 240 V it clears 187 kA, at 415 V it clears 121 kA, at 500 V it clears 75.6 kA, and at 690 V it clears 3 kA. That 3 kA at 690 V is a hard limit; if your system runs 690 V with fault current above that, this breaker is not the fit. That means it can report its status and trip events back to a PLC or BMS — useful for remote monitoring in a distributed line-up. No undervoltage release is fitted, so if undervoltage protection is required, it must be added externally. Maximum power loss is 5.4 W, so heat dissipation in a sealed panel is manageable; no forced cooling required for a single unit. ## Environmental limits and approvals The basic switch variant is 3VA20635JQ320AA0, which is the internal switching mechanism.","metaTitle":"Siemens 3VA2063-5JQ32-0KL0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5JQ32-0KL0 molded case circuit breaker, 63 A rated, 3-pole, 187 kA interrupting at 240 VAC.
