Product FAQs
7 answersWhat hardware is required to install this withdrawable circuit breaker?
The ABB XT7HU310DEWW000XXX is the moving part only. It requires an ABB SACE Tmax XT7 Fixed Part, also known as a cradle, for a complete withdrawable installation.
What does the H in the XT7H frame designation indicate?
The H signifies a High interrupting capacity. This frame provides up to 100kA at 240VAC and 65kA at 480VAC for demanding industrial power distribution systems.
What protection functions are included in the LSI trip unit?
The electronic Ekip trip unit provides adjustable Long-Time, Short-Time, and Instantaneous protection. This allows panel builders to fine-tune the trip curve for precise selective coordination with downstream devices.
What is the advantage of a withdrawable mounting style?
A withdrawable configuration allows the breaker to be quickly racked in or out of the fixed cradle. This enables rapid maintenance, testing, or replacement without disconnecting the primary power cables.
How does the withdrawable design enhance operator safety?
The withdrawable design allows the breaker to be racked out to a disconnected or test position. This provides physical isolation from the live bus before maintenance is performed on the circuit.
Can the XT7H series replace older GE Spectra breakers?
Yes, the ABB Tmax XT7 series is engineered as a modern upgrade path for discontinued General Electric molded case circuit breakers. It can replace legacy 1000A GE frames when paired with the appropriate retrofit hardware.
Can communication modules be added to this XT7 breaker?
Yes, the Ekip electronic trip units support optional communication modules for protocols like Modbus, Profibus, and Ethernet. These modules connect directly to the circuit breaker terminal box for integration into facility energy management systems.
