Breaking capacity is the headline: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 9 kA at 690 V. Continuous current derates with ambient temperature: 630 A at 40 °C, 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. Physical envelope: 110 mm deep, 138 mm wide, 248 mm tall. That 138 mm width across three poles is standard for this frame size; verify the gland plate cutout and busbar spacing before committing the panel layout. ## Auxiliary hardware and release configuration The UVR ensures the breaker trips on loss of control voltage — standard for safety disconnects or emergency-stop chains where you want fail-safe opening. Trip indicator is present, no voltage trigger function, no communication module, and no ground-fault monitoring. This is a straightforward line-protection breaker — not a metering or GFCI variant. The storage maximum exceeds the operating range — that governs shipping and warehousing, not running conditions.","metaTitle":"Siemens 3VA2463-7HL32-0CH0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens 3VA2463-7HL32-0CH0 SENTRON molded case circuit breaker, 630 A continuous at 40 °C, 3-pole, line protection, 110 mm depth.
