Product FAQs
6 answersWhat specific trip unit is included with the ABB XT4HU32501Y8000XXX?
This model is equipped with an Ekip DIP LSI electronic trip unit. It uses dip switches for configuring adjustable long-time, short-time, and instantaneous overcurrent protection settings.
What mounting style and connection type does this breaker use?
The XT4HU32501Y8000XXX is a fixed-mount circuit breaker configured with standard front terminals for line and load connections.
What is the maximum UL voltage rating for this XT4H breaker?
While its standard high-interrupting capacity is measured at 480V AC, the breaker is fully UL listed for a maximum operational voltage of 600V AC.
Can I use this breaker to replace a GE Tmax XT4 series component?
Yes. Following ABB's integration of GE Industrial Solutions, this circuit breaker is fully cross-listed. The catalog number XT4HU32501Y8000XXX functions as an exact replacement for both ABB and GE Tmax XT applications.
How does the Ekip DIP LSI trip unit support system safety and reliability?
The solid-state LSI trip unit allows for precise selective coordination in your power distribution system. By properly adjusting the pickup and delay settings, you can ensure that only the breaker nearest a fault trips, isolating the hazard without dropping power to the entire facility.
Where is this 250A XT4 frame typically applied within an electrical facility?
This breaker is suitable for main and feeder distribution roles. Its compact footprint and high breaking capacity make it ideal for low voltage switchboards, motor control centers, and secondary panelboards.
