Description
Engineered for demanding electrical systems, the LA36250-1021 provides 250A of thermal-magnetic protection. This L-frame device comes equipped with a 120-240VAC shunt trip, enabling remote disconnection for enhanced facility control. The breaker mounts into Square D I-Line panelboards and switchboards. When transitioning to newer equipment, substitute this legacy component with the LJA36250U31X. Rated 30kA at 480VAC, it features an adjustable magnetic trip for precise short-circuit tuning.Specifications
