FHL36020 - 20 Amp Circuit Breaker

FHL36020 - 20 Amp Circuit Breaker

When your circuit breaker fails or begins nuisance tripping, getting the right replacement is about more than matching the amperage. The mounting style, voltage rating, trip characteristics, and pole configuration all need to align with the existing equipment to keep the electrical system operating as intended. The Square D FHL36020 is designed to provide the same form, fit, and function as the original breaker, making it a dependable replacement circuit breaker for maintaining compatible Square D I-Line panelboards and existing commercial and industrial electrical distribution systems without unnecessary modifications.
