QF250A Siemens QPF Miniature Circuit Breaker 240 V 50 A 10 kA 60 Hz 2 Pole

Siemens GFCI circuit breakers are UL listed and CUL certified as class A devices. Current imbalances of 4-6 mA or more between load conductors will cause the ground fault sensor to trip the circuit breaker. These circuit breakers offer the self test feature as required by UL 943. UL suggests GFCI devices be tested every 30 days after installation to ensure they are properly working. Testing gfci's on A monthly basis is a good idea that is sometimes forgotten. The self test feature enables the GFCI to automatically and continuously test itself to ensure that it is working properly. If it is detected that the device has been compromised, the device trips itself. This will help guarantee the best protection is given to your home at all times. Note for the 2 pole GFCI: A load neutral is not required on the circuit. However, the white line neutral (pigtail) must be connected to the panel neutral for the device to function. The Siemens 2-Pole GFCI circuit breaker can be installed on A 120/240 V ac single phase, 3 wire system, the 120/240 V ac portion of A 240/120 volt, 3 phase, 4 wire system, or on A 208Y/120 volt, 3 phase, 4 wire system. When installed on these systems, protection is provided for 2 wire, 240 V ac or 208 V ac circuits; 3 wire, 120/240 V ac circuits. The Siemens 1-Pole GFCI circuit breaker is to be installed on A single-phase circuit rated 150 V to ground or less. Make sure you're protected around pools and spas. GFI breakers are commonly used around kitchens, bathrooms, laundry rooms, swimming pools and spas or anywhere you may come in contact with water. Gfci's are crucial to you and your family's safety at home. All products are new. A must use for kitchens, bathrooms, pools, spas, car wash, motor home, or around wet areas.
