Square D - 300 Amp, 3 Pole, Panel Mount Molded Case Circuit Breaker - Electronic Trip, Multiple Breaking Capacity Ratings


Item #: 56760887
Brand: Square D
Model #: MJL36300
Exact Tooling IR#: 04

Features and Benefits

MCCB (Molded Case Circuit Breakers) are designed to protect against overloads and short circuits in both low and high power applications. Trip settings are adjustable and they are thermal and thermal-magnetically operated. The current rating is up to 2,500 amperes.
Electronic tipping mechanisms provide overload and short-circuit protection with enhanced coordination capabilities and can include integral ground-fault detection.
