Overview
The General Electric TEY120 is a compact, bolt-on molded case circuit breaker designed for lighting and power distribution applications. This 1-pole thermal magnetic circuit breaker has a 20A current rating and 277VAC voltage rating. It delivers an interrupting rating of 14kAIC at 277V. This lot includes 5 units suitable for replacing worn or failed breakers in existing GE Q-Line panelboards.
Key Features
- Bolt-on connection type with long-time and instantaneous trip functions
- Thermal magnetic trip mechanism providing protection against both overloads and short circuits
- Secure installation in grounded 480Y/277V AC panelboards, supporting both copper and aluminum conductors
- Manufactured as part of the GE Q-Line series
- Non-interchangeable trip unit ensures consistent performance
- Single-pole (1P) configuration for single-phase applications
