General Electric | TJJ426125 | Circuit Breaker | 125A | 2-Pole | 600V

General Electric TJJ426125 circuit breaker is a 125A, 2-pole, 600V protective device designed for reliable interruption of fault currents in electrical panels. Built for maintenance, retrofit, and replacement projects where exact specifications matter, this GE component helps keep power systems safe and compliant.

What makes the TJJ426125 unique

• 125A single-trip rating provides robust protection for feeders and branch circuits while allowing normal load demands.
• 2-pole design ensures simultaneous disconnection of both conductors, improving fault isolation in 600V systems.
• 600V maximum voltage rating accommodates higher-energy distribution applications typical in commercial and light industrial settings.
• Part number as the best compatibility reference TJJ426125 is the precise identifier to match GE panels, enclosures, and bus configurations.
• Versatile use cases: maintenance, retrofit, and replacement in existing power distribution setups.

How to ensure a perfect fit Before ordering, verify the breaker fits your panel model and voltage/current specs. Use the exact part number (TJJ426125) to check compatibility with your GE equipment and any aftermarket upgrades.

Practical installation and safety tips This protective device should be installed by a qualified electrician. Steps to consider:

• Disconnect power and lockout/tagout the circuit before handling the breaker.
• Confirm the panel type and bus configuration match the TJJ426125's trip characteristics and mounting footprint.
• Follow local electrical codes and the panel's manufacturer guidelines during replacement.

Ideal for: facilities upgrading to GE protection devices, service panels requiring replacement for 2-pole 600V circuits, and retrofits where maintaining the original spec ensures warranty and performance continuity.
