Product Description
This Q-Line Type THQC molded case circuit breaker provides reliable overcurrent protection for residential and commercial branch circuits. Rated 20A at 120/240 VAC single phase with a 10 kA interrupting capacity, it features long-time and instantaneous trip functions in a compact, lug-lug configuration for line and load terminations. The unit supports copper or aluminum conductors from 14 to 8 AWG (12 to 8 AWG on load where specified) and mounts via plug-in or 35 mm DIN rail depending on panelboard configuration. A quick make/quick break toggle actuator, common trip bar design, and clear trip indication enhance safety and serviceability. The breaker is UL 489 listed with HACR rating and aligns with GE panelboard applications requiring THQC frame devices. Dimensions are approximately 3-9/32 in H x 1 in W x 2-3/8 in D, enabling dense installations while maintaining accessible wiring space. Use where non-interchangeable trip thermal-magnetic protection and THQC compatibility are required.
