Product FAQs
7 answersDoes the MA3800FS include a trip unit?
No. The MA3800FS is a frame-only unit. It requires a separate, interchangeable MA-series trip unit to provide thermal-magnetic overcurrent protection.
What is the purpose of the Saf-T-Vue window on this frame?
The Saf-T-Vue window allows electricians to visually inspect the internal contacts of the breaker. This provides an extra layer of safety by confirming whether the circuit is physically open or closed.
Which panelboards are compatible with the MA3800FS breaker frame?
This bolt-on frame is designed for installation in legacy Westinghouse PRL4 panelboards, switchboards, and motor control centers, as well as compatible Eaton Series C enclosures.
What is the interrupting capacity (AIC) for this breaker frame?
When paired with a standard trip unit, the MA3800FS frame is rated for 42 kA at 240V AC, 30 kA at 480V AC, and 22 kA at 600V AC.
Can the MA3800FS replace older MA3800 or HMA3800 breakers?
Yes, this frame serves as an exact physical cross-reference for aging Westinghouse MA3800, MA3800F, and HMA3800 breakers, allowing you to maintain your existing electrical infrastructure.
What type of lugs does the MA3800FS frame accept?
The frame is compatible with standard MA-series lug kits, such as the T800MA1 or TA700MA1. Lugs are typically selected based on your specific wire gauge and conductor material requirements.
Is the MA3800FS compatible with Eaton or Cutler-Hammer systems?
Yes. Eaton acquired the Westinghouse distribution equipment business. The MA3800FS is physically and electrically interchangeable with equivalent Eaton and Cutler-Hammer MA-frame breakers.
