Siemens Q220EG Circuit Breaker – QEB Series – 20A – 2 Pole – 120/240VAC – Plug-On – GFEP (30mA) – Thermal Magnetic

The Siemens Q220EG is a QEB Series molded case circuit breaker designed for dedicated equipment protection where standard GFCI devices may cause nuisance tripping. Rated at 20A and 120/240VAC, this 2-pole breaker provides ground-fault equipment protection (GFEP) with a 30mA trip threshold, making it suitable for industrial and commercial applications such as heat trace systems and pump loads.

Unlike standard 5mA GFCI breakers used for personnel protection, the Q220EG is engineered specifically for equipment protection, allowing greater tolerance for normal leakage currents while still providing reliable fault detection. Its plug-on design allows direct installation into compatible Siemens load centers and serves as a replacement for legacy QE220 models.

This breaker includes thermal-magnetic protection with Long-Time, Instantaneous, and Ground Fault (LIG) trip functions, along with a pigtail neutral connection for proper system integration.
