MHL361000 - 1000 Amp Circuit Breaker

MHL361000 - 1000 Amp Circuit Breaker

When reliability and protection matter most, the MHL361000 molded case circuit breaker delivers. Engineered by Schneider Electric / Square D, this 3-pole unit supports up to 600V AC and carries a 1000A current rating. It’s built to handle demanding electrical systems, offering a high interrupting capacity (e.g. 65 kA at 480V, and 25 kA at 600V) to safely break high fault currents without damage. This breaker is designed to integrate cleanly into your distribution panel or industrial switchgear. With feed-through lugs on both line and load sides, installation is streamlined and wiring flexibility is enhanced. Thanks to its built-in thermal-magnetic trip mechanism (with long-time and instantaneous protection), it shields circuits from both overloads and short circuits. Its solid construction gives you dependable performance day in and day out.
