160 A MCCB with ETU850 — selectivity and SCCR headroom
The communication function onboard allows integration into a power monitoring or control system, so the breaker can report status and trip events without additional interface modules.
At 105 mm wide, 181 mm tall, and 86 mm deep, this 3-pole MCCB fits standard panel-mount cutouts for the 3VA2 frame size. No undervoltage release fitted, so if your design requires UVR for emergency stop or undervoltage protection, you'll need the accessory version or an external relay. Maximum power loss is 19.7 W — relevant for thermal management inside a sealed enclosure; ensure adequate ventilation or derating if multiple breakers are ganged. The continuous current rating holds at 160 A across the full 40–70 °C range (–), so no thermal derating is needed within that band — a useful feature for warm panel environments.
