Product FAQs
8 answersWhat panelboards are compatible with the HDA36100U33X?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It mounts directly to the internal bus stack using plug-on jaws, saving installation time compared to traditional bolt-on breakers.
What does the U33X suffix mean on this PowerPact breaker?
The U33X suffix indicates that the breaker is equipped with a Micrologic 3.2S electronic trip unit. This solid-state unit provides adjustable Long-Time, Short-Time, and Instantaneous (LSI) protection, allowing for precise overcurrent coordination.
Does this breaker provide ground fault protection?
No. The Micrologic 3.2S trip unit provides LSI protection only. If your application requires ground fault protection, you will need a breaker with an LSIG trip unit.
How do you wire the line and load sides of this breaker?
The line side does not require wiring, as it uses I-Line plug-on jaws that connect directly to the panelboard bus. The load side features mechanical lugs that accept 14 to 3/0 AWG aluminum or copper conductors.

No, this is a standard-rated circuit breaker. Per National Electrical Code (NEC) guidelines, it is rated for 80 percent continuous load operation.
Can this 3-pole breaker be applied in a single-phase system?
Yes. Manufacturer specifications state that 3-pole PowerPact H-frame breakers with standard Micrologic trip units can be used for single-phase applications on 240VAC circuits by utilizing any two poles.

This specific model is configured for a standard ABC phase connection on the I-Line busbar stack.
