The ETU860 electronic trip unit gives you adjustable long-time (tr 0.5–25 s), short-time (tsd 0.05–0.5 s), and ground-fault protection with summation-current sensing on L+N. N-conductor protection is adjustable OFF, 50%, or 100%. ## Integration notes for the panel builder The 280 mm width means it occupies roughly 11 inches of rail space — plan gland-plate entry and cable bending radius accordingly.","metaTitle":"SENTRON 3VA2510-7KQ42-0AA0 MCCB, 1000 A, 440 kA at 240 V","metaDescription":"SENTRON 3VA2510-7KQ42-0AA0 4-pole molded case circuit breaker, 1000 A rated current, 440 kA breaking capacity at 240 V.
