GE TJD422300 - 300 A, 240 V, 2-Pole Circuit Breaker | AmpState

GE TJD422300 is a robust 2-pole molded-case circuit breaker designed to guard branch circuits in panelboards and load centers. With a 300A rating at 240V, it delivers reliable overcurrent and short-circuit protection for residential, commercial, and light industrial applications.

Designed for dependable, space-efficient protection

• Compact molded-case design minimizes space usage in crowded panels, making it easier to fit into existing enclosures without sacrificing protection.
• Thermal-magnetic trip unit provides stable, repeatable protection across varying temperatures and load conditions, combining slow-responding thermal sensing with fast magnetic actuation for a precise trip when faults occur.
• 2-pole construction simultaneously disconnects both live conductors, improving safety and reducing arc risk on high-current circuits.
• OEM-compatible with matching GE OEM load centers and panelboards, ensuring a seamless fit and straightforward replacement when upgrading or repairing panels.
