The ETU350 trip unit provides electronic overload and short-circuit protection with adjustable I²t curves — essential for selective coordination with downstream branch breakers. At 40 A continuous the breaker covers feeder and large motor circuits; the 60 A minimum adjustment range and 480 A maximum frame indicate the same physical frame accommodates higher-rated trip units if the load grows. ## Installation and Environmental Limits Dimensions of 86 mm depth × 140 mm width × 181 mm height fit standard SENTRON 3VA2 panel cutouts and busbar systems. Storage limits of -40 °C to 80 °C cover cold warehouses and shipping.","metaTitle":"Siemens 3VA2140-0HN46-0AA0 SENTRON MCCB, 40 A, 4-Pole, ETU35","metaDescription":"Siemens SENTRON 3VA2140-0HN46-0AA0 molded case circuit breaker, 40 A continuous, 4-pole, ETU350 electronic trip unit, 440 kA at 415 V AC.
