The 187 kA breaking capacity at 240 V and 121 kA at 415 V give it the headroom to handle high-fault scenarios typical of main feeders or large distribution panels — the 690 V rating of 9 kA tells you this is a line-protection device, not a motor-protection breaker, so verify your load type before specifying. Breaking capacity drops from 187 kA at 240 V to 121 kA at 415 V, then 55 kA at 440 V, 36 kA at 500 V, and 9 kA at 690 V — that steep curve means you size the SCCR for your actual line voltage, not the best-case number. Continuous current derates from 630 A at 40 °C to 520 A at 70 °C; at 70 °C ambient you lose roughly 17 % of the headline rating, so account for enclosure heat rise in the panel schedule. ## Integration and form factor The 3VA2463-5HL32-0DB0 measures 138 mm wide, 248 mm high, and 110 mm deep. IP40 on the front protects against tools and small wires. ## Trip unit and adjustability The ETU320 electronic trip unit offers adjustable long-time pickup (Ir) from 0.5 to 1.0 × Iu, with a configurable delay (tr) between 0.5 and 12 seconds. The 630 A maximum Ir setting matches the breaker's rated continuous current.","metaTitle":"Siemens 3VA2463-5HL32-0DB0 SENTRON MCCB, 630 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-5HL32-0DB0 molded case circuit breaker, 630 A rated, 3-pole, ETU320 electronic trip, 187 kA at 240 V.
