Built-in electronic trip unit type ET 1.0 provides better accuracy than standard thermal-magnetic trip units

The ET 1.0 trip unit cannot be field replaced, nor does it allow adjustment of the trip point setting

FIxed long time and adjustable instantaneous protection (2 to 10 times nominal ampere rating) is standard

Same dimensions, common mounting, bussing, cabling and door cut-out as PowerPact P-frame circuit breakers

Approximately 15% smaller installed volume than the MA/MH circuit breakers
