At 690 V the 9 kA figure limits application to lower-fault industrial networks or transformer-secondary positions. Continuous current rating derates with rising ambient temperature inside the enclosure: 630 A at 40 °C, 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. ## Auxiliary switches and release configuration The trip indicator confirms the breaker opened on fault vs. manual switching. No ground-fault monitoring version is included on this variant. ## Physical dimensions and panel fit Dimensions: 248 mm height, 138 mm width, 110 mm depth. The 3-pole frame fits standard MCCB mounting patterns in distribution panels. Depth of 110 mm is moderate — verify clearance for rear-connected busbars or cable terminations, especially in shallow enclosures.","metaTitle":"Siemens 3VA2463-5KP32-0BH0 SENTRON MCCB, 630 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2463-5KP32-0BH0 molded case circuit breaker, 630 A continuous at 40 °C, 3-pole, 187 kA breaking at 240 V.
