The electronic trip unit is an ETU550, which provides adjustable long-time, short-time, instantaneous, and ground-fault protection curves. No undervoltage release or voltage-trip accessory is fitted as standard; the communication function is present, so it can report status and trip events over a bus system if the panel is wired for it. ## Mounting and integration notes The motor-drive accessory option (product extension optional) allows remote reset or operation via a motor operator, useful for panels in hard-to-reach locations.","metaTitle":"Siemens 3VA2140-5JP42-0AA0 SENTRON MCCB, 40 A, 4-Pole, ETU55","metaDescription":"Siemens SENTRON 3VA2140-5JP42-0AA0 molded case circuit breaker, 40 A, 4-pole, ETU550 release.
