Product FAQs
7 answersWhat panelboards are compatible with the Eaton GHQRD1030 circuit breaker?
The GHQRD1030 is designed for use in Eaton Pow-R-Command lighting control panelboards, as well as Pow-R-Line 1a and Pow-R-Line 2a panelboards.
How does the remote operation function on the GHQRD1030 breaker?
This breaker features a built-in 24 Vdc solenoid mechanism that interfaces with the Pow-R-Command system. This allows facility managers to remotely switch the circuit on and off for automated lighting and load management.
Does the GHQRD1030 require a specific control bus for remote switching?
Yes. When installed in a Pow-R-Command panelboard, the breaker connects to a Breaker Control Bus (BCB). The BCB acts as the interface between the system controller and the breaker solenoid to provide status monitoring and remote control.
Can the GHQRD1030 be manually overridden if the automated control system fails?
Yes. The breaker includes a manual override feature, allowing personnel to manually switch the circuit on or off at the panelboard regardless of the remote control status.
What types of loads is the GHQRD1030 designed to control?
As part of the Pow-R-Command system, this breaker is typically used for automated commercial lighting systems, plug load management, and other energy management applications requiring remote switching.
What is the difference between the GHQRD1030 and a standard GHQ circuit breaker?
While both provide thermal-magnetic overcurrent protection, the GHQRD series includes a factory-installed 24 Vdc solenoid operator for remote switching capabilities. Standard GHQ breakers are strictly manually operated.
Is there a newer smart breaker alternative to the GHQRD1030?
Yes, the GHQRD series is the predecessor to the newer GHQRSP series of smart breakers. The GHQRSP1030 is the updated equivalent for modern Eaton Pow-R-Command installations.
