LS Electric MMS Motor Protection Switch
The LS Electric MMS Motor Protection Switch is a combination motor circuit protective device that integrates motor starting, manual isolating, short-circuit protection, and thermal overload protection in a single compact unit — eliminating the need for a separate MCB and overload relay in motor control circuits. The MMS range covers motor ratings from 0.1 kW to 45 kW with adjustable current setting dials and magnetic short-circuit trip elements factory-set for motor circuit duty. This combination device philosophy reduces panel wiring complexity, saves DIN rail space, and cuts component count in motor starter panels, making the MMS particularly attractive for Saudi Arabia's panel builders who are working to tighter MCC panel footprint specifications on large infrastructure and industrial projects.
The MMS motor protection switch provides Class 10 thermal overload protection with manual reset, magnetic short-circuit protection with trip current set to motor circuit standards (typically 12–15x In), phase loss detection, and a built-in 1 NO + 1 NC auxiliary contact for circuit interlocking. Trip indication is provided by a clear visual trip flag, and the device includes a trip-free mechanism that prevents manual override of a tripped condition — a safety feature required by IEC 60947-4-1 for motor protective devices. The MMS is designed for direct DIN rail mounting or screw mounting in panels and can be fitted with auxiliary contact blocks, undervoltage trip attachments, and shunt trip accessories to expand its functional capability for specific application requirements in Saudi industrial projects.
In Saudi Arabia's industrial panel building sector, the MMS has established a strong market position as the preferred single-device solution for motor protection in compact MCCs, distribution panels, and packaged equipment control boxes. Saudi contractors and OEM machine builders value the MMS for its compact footprint, simplified wiring, and reliable IEC 60947-4-1 performance at a price point significantly below European combination motor protection devices such as ABB MS-116 and Siemens 3RV2 series. Razz Middle East supports the Saudi market for LS Electric MMS with Sourced to order, technical assistance for current setting calculations, and cross-reference support against competing products.
Razz Middle East supplies the MMS range across all standard current settings for prompt dispatch on arrival from our Saudi Arabia warehouse. Volume pricing is available for panel builder customers procuring quantities for MCC projects.
