Description
Engineered for industrial power distribution, the ABB XT4HU3150AFJ000XXX is a 3-pole, 150A molded case circuit breaker from the SACE Tmax XT family. It utilizes a fixed thermal-magnetic trip unit to deliver consistent overload and short-circuit protection. This unit-mount MCCB installs into ABB SACE Tmax XT panelboards and enclosures. It serves as a seamless replacement for legacy T4H150 breakers. Rated for 150kAIC at 240V, the XT4H frame provides robust current-limiting performance.Specifications
