The ETU350 electronic trip unit provides LSI protection — long-time (Ir adjustable 500–1250 A), short-time (Isd 1.5–10 × Ir), and instantaneous (Ii fixed at 10 × In). That means the breaker discriminates between sustained overloads and high-fault bolted shorts, holding coordination downstream. ## Integrated accessories for panel fit Factory-fitted with a shunt trip on the left side (208–277 V AC 50/60 Hz, 220–250 V DC), two changeover auxiliary switches (code H), and one changeover trip-alarm switch. The shunt trip lets a remote safety relay or PLC drop the main breaker without reaching the handle; the auxiliary switches report breaker position back to the controller.","metaTitle":"Siemens 3VA2612-5HN32-0KH0 Circuit Breaker, 1250A, 55kA @ 41","metaDescription":"Siemens 3VA2612-5HN32-0KH0 IEC frame 1250 circuit breaker, 55kA breaking capacity @ 415V, ETU350 LSI protection.
