The SENTRON 3VA2510-6HN32-0HH0 is a 3-pole molded case circuit breaker rated for 1 000 A continuous current at 40 °C, with an ETU350 electronic trip unit. The interrupting capacity at 240 V hits 242 kA, at 415 V it's 187 kA, and at 690 V it still holds 74 kA, so it handles high-fault scenarios across common industrial voltages.
Above that it drops: 955 A at 60 °C, 885 A at 65 °C, 815 A at 70 °C.
Dimensions are 320 mm high, 210 mm wide, 120 mm deep. The 210 mm width (8.3 in) and 120 mm depth (4.7 in) matter for enclosure back-panel layout — check gland-plate clearance and busbar reach.
Trip unit adjustability
The ETU350 release gives you adjustable long-time pickup (Ir) from 0.5 to 1 000 A, long-time delay (tr) from 0.5 to 17 seconds, short-time delay (tsd) from 0.04 to 0.4 seconds, and instantaneous pickup (Ii) up to 10 000 A. That range covers coordination curves for feeder and downstream branch protection.
