That 187 kA figure drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 9 kA at 690 V — so the real-world SCCR you spec depends on your system voltage, not the headline number. The trip unit is adjustable between 945 A minimum and 5670 A maximum, giving you selectivity headroom downstream. This is a 3-pole design built for line protection, with a communication function onboard — no separate module needed for basic connectivity. At 45 °C it carries 600 A, at 50 °C it's 570 A, and it steps down to 450 A at 70 °C. Maximum power loss is 162 W. Minimum trip setting is 945 A. This breaker suits a main or large feeder. For loads under 600 A, a smaller frame like the 3VA1 series may be a tighter fit.","metaTitle":"Siemens 3VA2463-5JQ32-0AA0 SENTRON MCCB, 630 A, 187 kA","metaDescription":"Siemens 3VA2463-5JQ32-0AA0 SENTRON molded case circuit breaker, 630 A continuous at 40 °C, 187 kA breaking at 240 V. 3-pole line protection with communication.
