The maximum power loss is 7.9 W, which is modest for a 63 A electronic-trip MCCB; you won't need forced ventilation for a single unit, but stack several in a row and the cumulative heat matters. ## What the ETU350 trip unit gives you The ETU350 is an electronic overcurrent release that provides adjustable long-time pickup (Ir), short-time pickup (Isd) with adjustable delay, and instantaneous pickup (Ii). That adjustability is the main reason to pick this over a fixed thermal-magnetic MCCB — you can dial in the coordination with downstream breakers without swapping trip units. No communication function, no phase failure detection, no ground fault monitoring — this is a straight line-protection breaker, not a power monitoring device. If you need those extras, you'd step up to the 3VA2 with the ETU600 or add external modules.","metaTitle":"Siemens 3VA2063-5HN36-0DA0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-5HN36-0DA0 molded case circuit breaker, 3-pole, 63 A, ETU350 release, 187 kA at 240 V.
