Overview
The General Electric TED134020 is a 3-pole molded case circuit breaker from GE’s E150 series, engineered for industrial and commercial electrical distribution systems. Rated at 20A with 480V maximum voltage, this breaker provides thermal-magnetic protection with long-time and instantaneous trip functions. The unit features load side lug terminals and standard interrupting capacity of 18kA at 480V, with bolt-on mounting.
Key Features
- Thermal-magnetic protection with long-time and instantaneous (LI) trip functions
- Fixed thermal and adjustable magnetic trip unit with line and load side lug terminals
- Bolt-on mounting compatible with A-Series and Spectra panelboards
- 18kA interrupting rating at 480V for short-circuit protection
- Compact E-frame design for industrial electrical cabinets and distribution panels
- Panel-mounted design without neutral pole, GFCI, or neutral protection
