Product FAQs
8 answersWhat does the S2 suffix mean in the GHB3030S2 catalog number?
The S2 suffix indicates the breaker is equipped with a factory-installed 240VAC shunt trip. This accessory allows the breaker to be tripped remotely via an external control signal, which is commonly used for emergency shutdowns or automated safety interlocks.
Which Eaton panelboards accept the GHB3030S2 circuit breaker?
This G-frame breaker is designed to bolt directly into Eaton Pow-R-Line 2 (PRL2), Pow-R-Line 3 (PRL3), and Series C panelboards. It is not compatible with standard residential load centers.
Does the GHB3030S2 require a separate mounting kit for installation?
No, this is a bolt-on circuit breaker that mounts directly to the chassis of compatible Pow-R-Line and Series C panelboards. The bolt-on design provides a secure connection suitable for high-vibration commercial and industrial environments.
What are the wiring requirements for the terminals on the GHB3030S2?
The breaker comes with standard lugs that accept 10 AWG to 1/0 AWG conductors. The terminals are dual-rated for both copper and aluminum wiring, giving you flexibility during installation.
Are the thermal and magnetic trip settings adjustable on the GHB3030S2?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The Long-Time and Instantaneous (LI) protection parameters are factory-set and cannot be modified in the field.
Is the GHB3030S2 suitable for direct current (DC) control panels?
Yes, in addition to its AC ratings, this breaker is rated for 125/250VDC with a 14kA interrupting capacity, making it suitable for industrial DC control and distribution circuits.
How does the 240VAC shunt trip on the GHB3030S2 enhance facility safety?
The integrated shunt trip allows the breaker to be wired into facility fire alarms, emergency stop buttons, or other safety relays. When a hazard is detected, the system can automatically open the breaker to disconnect power without requiring an operator to manually flip the handle.
Can I install the GHB3030S2 in a panelboard designed for F-frame breakers?
No, the GHB3030S2 is a G-frame circuit breaker. It has different physical dimensions and mounting configurations than F-frame breakers and must be installed in panelboards specifically designed to accept G-frame units.

- MWMARK W.Verified BuyerReviewingEaton / Cutler-Hammer GHB1020 - 20A 1 Pole Molded Case Circuit BreakerRated 3 out of 5 stars7/21/26Good Product, but Disappointed With the Service
Good product, but I was disappointed with the service. I accidentally placed two separate orders and ended up paying freight on both. I had requested that they combine the orders, and had that been done with the freight waived, it would have saved me money.
Other than that, everything was good. I’m just disappointed that no one communicated this to me.
