The Siemens 3VA2510-5HL32-0KC0 is a SENTRON molded case circuit breaker (MCCB) rated for 1000 A continuous current across a 40 °C to 55 °C ambient range, with a 3-pole configuration and an ETU320 electronic trip unit for line protection. Its interrupting ratings reach 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V, making it a high-interrupting-capacity breaker suited for main or feeder protection in industrial power distribution panels.
At 240 V the breaker clears 187 kA; at 415 V it clears 121 kA; at 690 V it clears 53 kA.
Thermal derating and continuous current
At 60 °C the rating drops to 955 A; at 65 °C to 885 A; at 70 °C to 815 A. The adjustable long-time pickup Ir ranges from 400 A to 1000 A, so the breaker can be fine-tuned to match the actual load without swapping the frame. The ETU320 trip unit also offers adjustable short-time (tr: 0.5 to 17 s) and instantaneous pickup (li: 1500 A to 10 000 A).
Dimensions: 210 mm wide, 320 mm high, 120 mm deep.
