No. This breaker features a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings for both long-time and instantaneous protection.
What frame size is the HDL26050?
It is part of the Square D PowerPacT H-Frame family. This frame size is standardized for 15A to 150A breakers, allowing for consistent mounting dimensions across different amperages.

Yes, all PowerPacT circuit breakers feature an integral push-to-trip button on the cover, allowing you to manually trip the breaker to verify the mechanism is working correctly.
What safety precautions are required when installing this breaker?
Always de-energize the switchboard or control panel before installation. Ensure all wire connections are torqued to the manufacturer specifications printed on the breaker label to prevent overheating.
