Built for robust industrial applications, the Square D QDA222254 is a 2-pole, 225A molded case circuit breaker. As part of the PowerPacT Q-Frame series, it delivers dependable thermal-magnetic protection with fixed long-time and instantaneous (LI) trip functions. Designed for quick integration, it mounts into Square D I-Line panelboards and switchboards. It replaces older Q222254 models. This 240VAC breaker features a BC phase connection, Visi-Trip indicator, and is HACR rated.
What panelboards are compatible with the QDA222254 circuit breaker?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection and is not compatible with standard QO, Homeline, or NQOD load centers.
Does the QDA222254 replace any older Square D circuit breakers?
Yes, the PowerPacT Q-Frame QDA222254 is a direct replacement for the older legacy Q222254 circuit breakers used in I-Line panelboards.
What size wire can be used with the lugs on the QDA222254?
The factory-installed box lugs accept 4 AWG to 300 kcmil aluminum or copper conductors.
Can the QDA222254 be used on 208Y/120V systems?
Yes, while it has a maximum voltage rating of 240VAC, it is fully rated for use on 208Y/120VAC systems, providing a 25kA interrupting capacity at both voltages.
Does this breaker include a push-to-trip button for testing?
Yes, PowerPacT Q-Frame breakers feature an integral push-to-trip button in the cover to manually trip the circuit breaker. This allows for safe and easy testing of the tripping mechanism during regular preventive maintenance.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. Both the thermal and magnetic trip settings are fixed on this model.
How does the I-Line mounting system work on the QDA222254?
The I-Line mounting system uses a plug-in design where the breaker jaws snap directly onto the panelboard busbar stack. This allows for faster installation and eliminates the need for bolted bus connections on the line side.
Does the QDA222254 have a visual trip indicator?
Yes, the breaker handle assumes a center tripped position when a fault occurs, providing a clear visual indication that the breaker has tripped.
