The 110 mm depth and 184 mm width fit standard MCCB footprints; the 248 mm height means it clears most 600 mm tall enclosures with room for gland plates above. ## Interrupting capacity by voltage This breaker delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. The steep drop at 690 V means it's not the right choice for 690 V main feeders unless your fault current is well under 9 kA — but at 240–480 V it handles nearly any service entrance or subfeed.","metaTitle":"Siemens 3VA2463-5KP42-0AA0 SENTRON MCCB, 630 A, 4-Pole, ETU8","metaDescription":"Siemens SENTRON 3VA2463-5KP42-0AA0 molded case circuit breaker. 630 A continuous, 4-pole, ETU850 trip unit. 187 kA at 240 V.
