Overview

The GE TJJ426250 is a 250-amp, 2-pole molded case circuit breaker rated for 480-volt systems. It belongs to GE's TJJ family, a line of breakers engineered for commercial and light industrial power distribution. With a 30,000-amp interrupting capacity, this breaker is built to detect and safely clear fault currents, protecting downstream wiring and equipment from damage caused by overloads or short circuits.

This particular unit is sold in used condition and has been inspected for operational readiness. For facilities managers or electricians sourcing replacement breakers for existing GE switchgear, a used TJJ426250 can offer considerable savings over a new unit while still delivering the same core protection. Buyers should confirm that their panelboard accepts TJJ-series breakers and should have any used electrical component professionally evaluated prior to energizing it in a live system.
