General Electric TEF124030 30A 2-Pole 480 V Circuit Breaker

General Electric TEF124030 is a 30A, 2-pole 480V circuit breaker designed to protect electrical circuits in commercial and industrial environments. This GE device interrupts fault currents and ensures safe shutdown when overloads occur, safeguarding wiring and connected equipment.

Key specifications

• Part number: TEF124030
• Current rating: 30 amperes
• Poles: 2
• Voltage rating: 480 volts
• Brand: General Electric

Why this two-pole design matters

With a two-pole configuration, this breaker disconnects both hot conductors in a 480V circuit, providing complete circuit isolation and reducing the risk of arc-related hazards during maintenance or fault events.

Ideal use cases

• Industrial equipment feeders operating at 480V AC
• Commercial power distribution where a 30A branch circuit needs reliable protection
• Replacement for GE TEF-series breakers in compatible panels and assemblies (verify fitment for your setup)

How to use and install

Install only in a power-off state and follow all applicable electrical codes. Ensure the system voltage aligns with the 480V rating and the load requires up to 30A protection. Keep the part number TEF124030 on hand for ordering replacements or additional spares.

Practical tips

• Before replacing an existing breaker, confirm that the electrical panel or distribution board accepts TEF-series devices.
• Label circuit details clearly after installation to simplify future maintenance or troubleshooting.
