Siemens QE120 – 20A GFEP Miniature Circuit Breaker Popular

Engineered for reliable equipment protection, the Siemens QE120 is a 20A, single-pole miniature breaker. It utilizes a 30mA ground-fault trip threshold to defend machinery and heat trace cables against line-to-ground faults, avoiding the nuisance tripping of standard 5mA personnel GFCIs. This plug-on device mounts into Siemens load centers and P1 panelboards. It is replaced by the Q120EG in newer installations. Rated for 10kAIC at 120VAC, this breaker includes a pigtail neutral.
