Material Compliance and Certifications

Manufacturer specifications identify the LH36175 as UL Listed and CSA certified. These certifications provide useful reference points when confirming the breaker against the requirements of an existing installation.

Where It Works Best

The LH36175 175A 3-pole circuit breaker is best suited to existing and legacy I-Line electrical distribution equipment that requires this particular combination of electrical ratings, thermal-magnetic protection, connections, and physical dimensions.

A useful compatibility check starts with 175 amps and three poles, but it shouldn't stop there. Confirm that the application calls for an LH thermal-magnetic breaker and that the system requirements correspond with its 25 kA interrupting rating at 600VAC. Also check the manufacturer's specified magnetic characteristics—875A hold current and 750A tripping current—against the application requirements.
