Overview
The General Electric THQP220 is a 2-pole, 20-amp molded-case circuit breaker designed for residential and light commercial electrical systems operating at 120/240V. This breaker combines thermal and magnetic trip elements to detect both overload and short-circuit conditions, disconnecting power instantly when faults occur. THQP breakers are a smaller, smarter solution that are half the width of standard breakers and allow the use of smaller load centers. The THQP220 delivers consistent, dependable protection with UL-listed thermal-magnetic technology.
Key Features
- Two breakers fit in the place of one full-size unit — compact 1-inch width design saves space in load centers
- Supports 14 to 8 AWG copper or 12 to 8 AWG aluminum wire for flexible installation
- Printed face designation simplifies circuit tracking and maintenance
- Plug-in mounting for quick, tool-free installation and replacement
- Internal common trip for synchronized 2-pole operation
- UL listed and CSA approved for safety compliance

Typical Applications
Ideal for heating, air conditioning, and refrigeration systems. The THQP220 is suitable for branch circuits in residential panels, light commercial installations, and renovations where space constraints favor compact breaker designs. Common uses include protecting circuits for lighting, receptacles, and small motor loads in 120/240V single-phase distribution panels.
