SENTRON 3VA2163-5JQ32-0CA0 — 63 A MCCB with ETU560 and UVR
It carries a continuous current Iu of 63 A at 40 °C, holding that rating through 50 °C before derating to 60.6 A at 55 °C and 53.6 A at 70 °C. Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V — giving it strong SCCR headroom for most industrial distribution panels. The ETU560 electronic trip unit handles the overcurrent protection logic. An undervoltage release (UVR) is integrated as the auxiliary release design, and the part includes a communication function for integration into higher-level monitoring or control schemes.
The 3-pole form factor fits 3-phase line protection duty. Maximum power loss is 6.5 W.
The ETU560 trip unit provides adjustable long-time, short-time, instantaneous, and ground-fault protection curves — not a fixed thermal-magnetic, so coordination studies can be fine-tuned.
