ABB PL702U-K30 Circuit Breaker

This breaker is exclusively designed for ABB ProLine UL 67 panelboards. It is not compatible with standard ABB miniature circuit breaker enclosures or standard load centers.

The breaker features separated electrical and mechanical connections. It plugs directly into the ProLine busbar for electrical contact and secures mechanically to the chassis using a non-energized bolt-on screw.

When installed in a ProLine panelboard, the system provides an IP20 touch-safe environment. The mechanical mounting screw carries no current, protecting installers from accidental shock during maintenance or installation.

The K-curve thermal-magnetic trip unit is optimized for loads with high inrush currents, such as motors, transformers, and specific industrial equipment. It prevents nuisance tripping during normal startup spikes while maintaining fast response times to short circuits.

Yes, the PL702U-K30 utilizes ABB current-limiting technology. It is engineered to clear short-circuit faults rapidly, reducing let-through energy and minimizing potential damage to downstream circuits and equipment.

ABB has transitioned the PL700U series to the PLU700M series under their life cycle management program. The PLU702M-K30 is the direct replacement and offers the same form, fit, and function for 30A, 2-pole applications.
