Product FAQs
6 answersWhat is the difference between an Eaton GHBS1020D and a standard GHB1020 circuit breaker?
The GHBS1020D includes a factory-installed solenoid operator designed for remote switching in automated lighting panels. Standard GHB breakers rely strictly on manual operation and lack this internal solenoid.
Which specific panelboards is the GHBS1020D designed to fit?
While it shares the standard G-frame bolt-on footprint, the GHBS series is specifically engineered to integrate with Eaton Pow-R-Command automated lighting control panelboards.
How does the remote switching function operate on this breaker?
The breaker receives direct pulse-on and pulse-off signals from the Pow-R-Command system controller. This actuates the internal solenoid to open or close the circuit remotely, providing automated control without requiring external lighting contactors.
What is the recommended replacement for Pow-R-Command panels built after 2001?
Eaton superseded the GHBS style breakers for newer smart panels. If you are installing a breaker in a Pow-R-Command panelboard manufactured in 2001 or later, the GHQRSP series, specifically the GHQRSP1020, is the recommended alternative.
Is the GHBS1020D rated for daily commercial lighting control?
Yes. Because it is designed for automated lighting networks, this single-pole breaker carries an SWD (Switching Duty) rating. This signifies the internal contacts are built to withstand the repetitive daily switching of commercial fluorescent lighting loads without premature wear.
Can this breaker provide branch circuit protection for HVAC equipment?
Yes. The GHBS1020D is fully HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires inverse-time circuit breaker protection.
