The ETU350 electronic trip unit gives you adjustable long-time pickup (Ir) from 0.5 to 1.0 × In (500–1 000 A), short-time delay (tsd) from 0.04 to 0.4 s, and instantaneous pickup (Ii) up to 10 000 A — so you can shape the curve for selectivity with downstream breakers. Current rating holds at 1 000 A up to 55 °C ambient; above that, derate to 955 A at 60 °C, 885 A at 65 °C, and 815 A at 70 °C. That thermal curve is the real-world limit for a hot panel — size your load accordingly. Dimensions are 320 mm high × 210 mm wide × 120 mm deep (12.6 × 8.3 × 4.7 in). Mounts in a standard panel cutout; the 210 mm width fits common MCCB footprints. Spring-cage or screw terminals accept cable sizes typical for 1 000 A class — verify lug kit compatibility with your bus bars.","metaTitle":"Siemens 3VA2510-5HN32-0HC0 SENTRON MCCB, 1000 A, 187 kA at 2","metaDescription":"Siemens SENTRON 3VA2510-5HN32-0HC0 molded case circuit breaker, 1000 A rated, 187 kA breaking at 240 V.
