Description
Engineered for power distribution, the GE TJD432300 provides 300A of reliable overcurrent defense. It utilizes a fixed thermal-magnetic trip mechanism for long-time and instantaneous (LI) protection. Designed with a bolt-on mounting style, this 3-pole breaker integrates into GE Spectra and A-Series panelboards. The ABB Tmax XT5 serves as a substitute when paired with a retrofit kit. Featuring a 22kAIC rating at 240VAC, it effectively interrupts faults. The unit comes equipped with load lugs.Specifications
