Product FAQs
6 answersWhich panelboards are compatible with the B360GFHH circuit breaker?
This bolt-on breaker is designed for installation in Siemens P1, P2, P3, P4, and P5 panelboards.
How is the neutral connection handled on this GFCI breaker?
The breaker features a white pigtail neutral that must be connected to the panel neutral bus for the ground fault detection circuitry to function, even if the load does not require a neutral.
What level of ground fault protection does the B360GFHH provide?
It provides Class A 5mA ground fault protection for personnel safety, complying with UL 943 standards.
What does the "HH" suffix indicate in the B360GFHH catalog number?
The "HH" designates a high interrupting rating of 65kAIC at 208Y/120VAC, providing enhanced fault clearing capabilities compared to standard BL series breakers.
Does the load current need to be balanced across all three phases for the ground fault sensor to work?
No, the ground fault device does not require the load current to be balanced among phases for proper operation. It measures residual differential current to detect faults and mitigate false tripping.
What is the difference between Siemens GFHH and EGHH series breakers?
GFHH breakers, like the B360GFHH, provide 5mA Class A personnel protection. EGHH series breakers provide 30mA equipment protection.
