Product Description
The Square D KHL36175 is a high-interrupting capacity 3-pole molded case circuit breaker engineered by Schneider Electric for heavy-duty commercial and industrial electrical distribution systems. Designed for unit-mount installation with standard feed-thru lug connections, this elevated-interrupting K-Frame breaker utilizes a thermal-magnetic trip unit to provide critical overload and short-circuit protection. Its robust bolt-on construction allows for secure integration into custom enclosures, switchboards, and distribution panelboards, maximizing system reliability under elevated short-circuit current conditions.
Key Features
-
Bolt-On Unit Mount Construction: Delivers simple, secure mechanical and electrical connections for feed-thru unit mounting in control panels and switchboards.
-
Dual Protection: Thermal-magnetic protection mechanics handle both long-time overcurrent overloads and instantaneous short circuits.
-
High Interrupting Capacity: Rated for up to 65 kA at 240 VAC and 35 kA at 480 VAC to accommodate systems with higher available fault currents.
-
Industrial Durability: Fully HACR rated for heating, air conditioning, and refrigeration applications.
