Information About QF120A
The QF120A is a Siemens GFCI circuit breaker engineered to enhance personnel safety by detecting ground fault currents and interrupting power when leakage exceeds safe thresholds. It incorporates a self-test mechanism that automatically checks GFCI functionality during operation. The breaker is designed for installation in Siemens EQ, EQL, SEQ, EQG, PL, and ES series load centers and is suitable for branch circuits serving HACR equipment. Its thermal-magnetic trip mechanism also provides reliable overload and short-circuit protection.
Key Features
- Integrated GFCI Protection: Provides Class A ground fault protection with a 0–5 mA trip range.
- Self-Test Functionality: Automatically verifies proper GFCI operation for continuous protection.
- 20 Amp Rating: Suitable for standard 120 V branch circuits.
- Single-Pole Design: Intended for single-phase residential and light commercial applications.
- Thermal-Magnetic Trip Unit: Delivers combined overload and instantaneous short-circuit protection.
- HACR Rated Construction: Approved for heating, air conditioning, and refrigeration equipment circuits.
- Siemens Load Center Compatibility: Designed for use in specified Siemens panelboard series.
The QF120A delivers the reliability and precision required for ground fault protection in Siemens residential and commercial electrical distribution systems.
