Above that it derates linearly: 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C. ## Trip unit and auxiliary contacts The ETU850 electronic trip unit provides adjustable long-time, short-time, instantaneous, and ground-fault protection curves — typical for a line-protection MCCB that needs coordination with downstream breakers. Maximum power loss is 5.4 W per pole, which adds up to about 16 W total heat inside the enclosure — worth checking against your panel thermal budget.","metaTitle":"Siemens 3VA2063-5KP32-0AB0 SENTRON MCCB, 63 A, 3-Pole, ETU85","metaDescription":"Siemens 3VA2063-5KP32-0AB0 SENTRON molded case circuit breaker, 63 A rated continuous current, 3-pole, ETU850 electronic trip unit, breaking capacity 187 kA at 240 V.
