The 4-pole configuration covers three-phase plus neutral, so it suits TN-S or TN-C-S systems where the neutral needs overcurrent protection. The 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. ## Mounting dimensions and panel integration The breaker measures 248 mm high, 184 mm wide, and 110 mm deep. The 184 mm width for a 4-pole frame means it occupies roughly 7.24 inches of DIN space — account for that when laying out the gland plate and busbar takeoffs. IP40 on the front protects against tools and solid objects larger than 1 mm; the enclosure sides and rear are open to the panel interior, so the overall panel IP rating governs.","metaTitle":"Siemens 3VA2463-7HL42-0AA0 SENTRON MCCB, 630 A, 4-Pole, ETU3","metaDescription":"Siemens 3VA2463-7HL42-0AA0 SENTRON molded case circuit breaker, 630 A continuous, 4-pole, ETU320 release, 330 kA at 240 V.
