The ETU350 electronic trip unit handles the overcurrent release, and an undervoltage release is integrated from the factory. Maximum power loss is 6.5 W. The 63 A continuous rating holds flat from 40 °C through 50 °C, then derates to 60.6 A at 55 °C and 53.6 A at 70 °C, so ambient temperature inside the enclosure matters when sizing for continuous load. The ETU350 overcurrent release provides electronic trip curves — not the fixed thermal-magnetic of the 3VA1 frame. That matters if you need adjustable long-time, short-time, or instantaneous pickup settings for selective coordination downstream. ## Deployment context The UVR coil draws from the control circuit; verify polarity and voltage rating before energizing.","metaTitle":"Siemens 3VA2163-7HN32-0CH0 SENTRON MCCB, 63 A, 3-pole, 330 k","metaDescription":"Siemens SENTRON 3VA2163-7HN32-0CH0 molded case circuit breaker, 63 A, 3-pole, line protection, ETU350 release, 330 kA at 240 V.
