Product FAQs
6 answersWhat panelboards accept the XT1NU3025AFF000XXX circuit breaker?
It is designed specifically for ABB ReliaGear neXT panelboards, ReliaGear SB switchboards, and Tmax XT enclosures. The ReliaGear neXT platform uses a modular bus stack that accommodates these breakers for rapid field modifications.
Which legacy ABB circuit breaker does the XT1NU3025AFF000XXX replace?
This Tmax XT1 breaker acts as a direct substitute for the legacy ABB T1N025TW molded case circuit breaker.
Is the XT1NU3025AFF000XXX suitable for solar or battery storage applications?
Yes. Because it carries a dedicated DC voltage rating up to 500VDC with a 35kA interrupting capacity, it is well suited for industrial DC control panels, solar installations, and battery storage systems.
Are the trip settings adjustable on the XT1NU3025AFF000XXX?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous protection parameters are factory set and do not require field calibration by the installer.
How does the XT1NU3025AFF000XXX mount into the panelboard?
It features a bolt-on connection. When paired with ReliaGear neXT panelboards, it utilizes spring-loaded primary disconnects that provide the speed of a plug-in installation with the security of a traditional bolted joint.
Does the XT1NU3025AFF000XXX support finger-safe installations?
Yes. When installed in ABB ReliaGear neXT panelboards, the system utilizes an IP20 finger-safe bus stack design to reduce the risk of accidental contact with live parts during maintenance.
