This 4-pole MCCB handles three-phase plus neutral for main feeder or large motor branch applications. The interrupting rating climbs to 187 kA at 240 V and stays at 121 kA at 415 V and 440 V — that's a high-fault MCCB, suitable for switchgear close to the transformer secondary. Compare that to a standard 65 kA MCCB at 480 V: this 3VA handles nearly double the fault current at 240 V, which matters when the upstream transformer is oversized or the service entrance has a high short-circuit capacity. ## Current derating — the real-world rating In a warm panel — say 50 °C — it's good for 593 A; at 60 °C, 557 A. If your panel runs hot (65 °C), you're down to 538 A. That derating curve matters when you're sizing the breaker for a continuous load in a non-air-conditioned enclosure. The breaker dissipates up to 162 W at full load. Footprint is 184 mm wide by 248 mm tall by 110 mm deep. That's a standard 4-pole MCCB form factor — it'll fit most existing MCCB mounting plates without redrilling. The shunt trip lets you remote-trip the breaker from a safety circuit or an emergency stop button — no separate undervoltage release needed. The I²t trip is adjustable (: design of I-trip / adjustable = Yes), so you can fine-tune the short-time pickup and delay to coordinate with downstream feeders.","metaTitle":"Siemens 3VA2463-5HL42-0JB0 SENTRON MCCB, 630 A, 4-Pole, Line","metaDescription":"Siemens SENTRON 3VA2463-5HL42-0JB0 molded case circuit breaker, 630 A rated, 4-pole, line protection.
