Material Compliance and Certifications

The supplied specifications for the LXL36300 G included no specific material-compliance information, certifications, or listings. For that reason, do not assume certifications or compliance with standards such as UL, IEC, RoHS, or REACH based on the part number, LXL designation, or other supplied specifications.

Where It Works Best

The LXL36300G 300A 3-pole circuit breaker is best evaluated for compatible existing or legacy electrical equipment that calls for an LXL, cable-in/cable-out, current-limiting molded case circuit breaker with matching electrical and physical specifications. It is especially important to match the 300A rating, three-pole configuration, voltage-specific A.I.C. ratings, MicroLogic™ thermal-magnetic configuration, and the supplied adjustable long-time, short-time, instantaneous, and ground-fault functions.
