Product FAQs
5 answersWhich panelboards and switchboards are compatible with this 1200A XT7 breaker?
This breaker is designed for integration with ABB ReliaGear neXT Panelboards, ABB ReliaGear Switchboards, and ABB SACE Tmax XT7 Enclosures.
What does the H in the XT7H frame designation indicate?
The H stands for High interrupting capacity. This specific frame provides a 65kA interrupting rating at 480V AC and up to 100kA at 240V AC.
What does the LSI designation mean on this electronic trip unit?
LSI stands for Long-Time, Short-Time, and Instantaneous trip functions. This adjustability allows panel builders and electricians to fine-tune the breaker's response curve for optimal selective coordination.
Can the trip settings on this 1200A breaker be adjusted in the field?
Yes, the Ekip DIP LSI electronic trip unit is fully adjustable. You can configure the pickup and delay settings for overloads and short circuits to match your specific load requirements.
Why use an electronic LSI trip unit instead of a standard thermal-magnetic breaker?
Electronic LSI trip units offer greater precision and repeatability than traditional thermal-magnetic breakers. They allow for exact adjustments to the trip curve, which is critical for protecting sensitive equipment and isolating faults in complex distribution systems.
