GE TEY315 - 15 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

GE TEY315 is a 15A, 480V, 3-pole bolt-on molded case circuit breaker from AmpState. Engineered for dependable branch-circuit overcurrent and short-circuit protection in panelboards and load centers, it pairs robust mechanical design with precise trip protection for demanding electrical environments.

Secure bolt-on mounting for a vibration-resistant connection

With a dedicated bolt-on mounting style, this breaker locks onto the bus with a rigid connection, reducing movement and arcing risk in installations subjected to vibration or equipment startup.

Reliable thermal-magnetic protection

The built-in thermal-magnetic trip unit continuously monitors temperature and magnetic fault currents, delivering stable and repeatable protection against overloads and short circuits. This dynamic response helps minimize nuisance trips while prioritizing rapid disconnection when a fault occurs.

OEM compatibility and installation simplicity

Designed to pair with matching GE OEM panelboards and load centers, TEY315 streamlines upgrades and replacements. Its bolt-on design is ideal for panel builders and field upgrades where a secure, serviceable connection matters most.

Ideal for a range of applications

This 3-pole, 15A, 480V breaker is suitable for protecting branch circuits in residential, commercial, and light industrial distributions. Use it to safeguard electrical drives, lighting, receptacle circuits, and other 3-phase loads that require reliable 480V protection.
