Its 160 A continuous rating holds flat from 40 °C through 50 °C (–), then derates to 150 A at 70 °C — useful when the breaker sits near other heat sources in a sealed enclosure. For DC applications, the rated operating voltage is 250 V DC; the manufacturer directs users to the 3VA device manual for DC switching power values.
Dimensions: 70 mm deep, 50.8 mm wide, 130 mm tall. Maximum power loss is 25.34 W — relevant for thermal budgeting inside a multi-breaker panel. The insulation voltage is rated 500 V, confirming suitability for 480/277 V and 400/230 V systems with margin.
