Siemens GFCI circuit breakers are UL Listed and CSA Certified
as Class A devices. Current imbalances of 4-6 milliamps or
more between load conductors will cause the ground fault
sensor to trip the circuit breaker.
These circuit breakers offer the new Self Test & Lockout
feature as required by UL 943. UL suggests GFCI devices be
tested every 30 days after installation to ensure they are
properly working. Testing GFCIs on a monthly basis is a good
idea that is sometimes forgotten. Now, the new Self Test
and Lockout 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 and locks out the homeowner from resetting
the device, reducing the possibility of the homeowner
incorrectly assuming that the device was tripped to prevent a
ground fault. This will help guarantee the best protection is
given to your home at all times.
Note: 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 120/240V AC single phase, 3 wire system, the 120/240V
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, 240V AC or
208V AC circuits; 3 wire, 120/240V AC circuits.
The Siemens 1-pole GFCI circuit breaker is to be installed only
on a single phase 120/240V AC system.
