Square D LIP36500 Circuit Breaker

The LIP36500 utilizes a bolt-on connection. Bolt-on units are physically fastened directly to the panelboard busbars. This provides a highly secure mechanical and electrical connection, which is strongly preferred in heavy-duty industrial settings to prevent arcing and withstand vibrations.

This breaker features an exceptionally high interrupting rating of 200kAIC at 480V. This means it can safely clear a fault current of up to 200,000 amps without sustaining catastrophic damage, making it ideal for heavy commercial and industrial facilities with large service entrances.

This unit is a Square D L-frame molded case circuit breaker. When sourcing a replacement or planning a new installation, verify that your switchboard or enclosure is specifically configured to accept L-frame bolt-on breakers.

The long time function provides thermal protection by tripping the breaker during sustained overloads to prevent wire overheating. The instantaneous function offers magnetic protection, immediately opening the circuit when a severe short circuit is detected to minimize equipment damage.

Yes, the LIP36500 can often replace other 500A L-frame bolt-on breakers, provided the panelboard accepts its specific dimensions and the 200kAIC interrupting rating meets or exceeds your system requirements. Always verify lug compatibility and physical space before substituting.
