Frequently Asked Questions
Where does the RMSP-LX11 mount on the motor starter protector?
The RMSP-LX11 mounts to the left side of the RMSP motor starter protector body. It is a side-mount accessory, not a front-mount block. Only one RMSP-LX11 can be fitted per motor starter protector unit. Ensure you are ordering the correct orientation — if you need a front-mount auxiliary block, that is a different part number.
What is the difference between the RMSP-LX11 and RMSP-FX11?
The RMSP-LX11 is a side-mount auxiliary block (mounts to the left side of the RMSP unit), while the RMSP-FX11 is a front-mount auxiliary block (mounts to the front face). Both provide 1 N.O. and 1 N.C. contacts. The correct choice depends on your panel layout and which face of the RMSP protector is accessible for auxiliary wiring.
Which RMSP motor starter protectors is the RMSP-LX11 compatible with?
The RMSP-LX11 is compatible with the Benshaw RMSP-32H (up to 32A), RMSP-63H (up to 63A), and RMSP-100H (up to 100A) motor starter protectors. It is not compatible with other Benshaw soft starter or contactor accessories outside the RMSP series. If you are unsure which RMSP unit you have, check the nameplate on the motor starter protector body or call us at 1-800-222-5129.
Can I install more than one RMSP-LX11 on a single unit?
No — only one RMSP-LX11 can be installed per motor starter protector unit. The left side of the RMSP body accommodates a single auxiliary block. If your application requires additional contact points, consider combining the RMSP-LX11 with an RMSP-FX11 front-mount block to maximize available auxiliary contacts on a single unit.
What is the RMSP series used for?
Benshaw RMSP series motor starter protectors are manual motor starters designed for direct-on-line motor starting in industrial control panels. They provide comprehensive motor protection including overload protection, phase failure protection, short-circuit protection, and motor starter protection — all in a compact DIN-rail mounted unit. They couple directly to Benshaw RMSC series contactors to form a complete combination motor starter assembly.
