Use cases and value

Install the TEY245 in panelboards and load centers that require reliable protection for 480V branch circuits. Its bolt-on mounting provides a secure connection in environments subject to vibration, while the thermal-magnetic trip ensures fast, predictable responses to overloads and short circuits. This makes it a smart choice for upgrading aging protection devices, expanding electrical capacity in commercial spaces, or reinforcing safety in light industrial facilities. By choosing a GE TEY245, you maintain system compatibility with GE OEM equipment and simplify maintenance with a known, widely supported protective device.

Practical installation and care

• Verify compatibility with your specific panelboard model and GE OEM lineup before installation.
• Use the bolt-on mounting method as designed to maximize connection rigidity and minimize movement under vibration.
• When replacing an existing device, match the amperage rating (45A) and voltage rating (480V) to preserve protection coordination across the distribution network.
• During installation, ensure the two poles trip together to maintain safe, simultaneous disconnection of both conductors.

GE TEY245 delivers a precise, dependable protection solution for 480V circuits, pairing proven thermal-magnetic protection with a rugged bolt-on design—so your panel distributions stay safer, more reliable, and easier to service.
