It carries a rated continuous current Iu of 1 000 A, which is the current it can carry continuously without tripping — that's the number you match to your bus or cable ampacity, not a motor full-load current. The ETU350 electronic trip unit gives you adjustable long-time (Ir) from 0.5 to 1 000 A and short-time (tsd) from 0.04 s to 0.4 s, so you can set the pickup and delay for selective coordination downstream. Breaking capacity is what decides whether this breaker survives a bolted fault without welding or exploding. At 240 V it interrupts 187 kA; at 415 V it's 121 kA; at 690 V it's still 53 kA. Those are the maximum fault currents the breaker can safely clear at each voltage level — if your available fault current at the panel exceeds the rating at your system voltage, you need a current-limiting fuse upstream or a higher-rated frame. The 1 000 A rating holds flat from 40 °C through 55 °C ambient; it derates to 955 A at 60 °C and 815 A at 70 °C, so if your enclosure runs hot you'll need to account for that in the load schedule. ## Deployment context and panel fit This is a 3-pole MCCB sized for main or feeder protection in switchboards and distribution panels. It measures 210 mm wide, 320 mm high, and 120 mm deep — those are the envelope dimensions you need for the mounting footprint and door cutout. The front face carries an IP40 protection class, meaning it's protected against tools and wires greater than 1 mm but not against water ingress, so it belongs inside a panel or enclosure, not on a washdown floor. Rated insulation voltage is 800 V, which covers 690 V systems with margin.","metaTitle":"Siemens 3VA2510-5HN32-0KA0 SENTRON MCCB, 1000 A, 187 kA at 2","metaDescription":"Siemens 3VA2510-5HN32-0KA0 SENTRON molded case circuit breaker, 3-pole, 1000 A rated, 187 kA breaking at 240 V.
