ABB MS132 Motor Starters & Transformer Protection

• MS132: motor protection and manual switching with screw terminals.
• MS132-K: the documented motor starter version with Push-in Spring terminals.
• MS132-T: control transformer protection with different tripping characteristics; ABB states that it should not be used for motor protection.
• Keep the complete suffix and Article Number when identifying a unit; a common family name does not establish equivalent duty.

Motor or Transformer: Confirm the Duty First

For motor protection, provide the motor nameplate current at the actual voltage and connection, starting duration and load duty. Choose a documented current-setting range that covers the motor requirement and follow the relevant setting instructions. Motor kW alone is insufficient for selecting an exact unit.

For a T-version transformer application, identify the transformer primary voltage/current and inrush conditions. Use the dedicated transformer-protection data rather than transferring a motor selection table. The existing historical model names and codes remain unchanged; confirm their exact version using ABB documentation.

Breaking Capacity, Standards & Coordination

Check Icu and Ics for the exact product at the operating voltage, together with prospective short-circuit current and any required back-up protection. A maximum family breaking-capacity claim is not a rating for every code or voltage.

ABB’s motor protection catalogue supplies IEC/EN 60947-2, 60947-4-1 and 60947-1 data for the relevant products. Use the correct product function and standard when specifying a T version. North American applications require the matching listing and installation conditions. For a motor starter with a contactor, select an ABB-tested combination under its stated coordination conditions.

Terminals, Accessories & Requesting a Quote

Check screw versus Push-in terminals, conductor sizes, installation space, ambient conditions and required auxiliary/signalling contacts or releases. Accessories, connecting links and contactor interfaces must be matched to the exact main device; control voltage applies to the selected release or other accessory where relevant.

Send the complete model and ABB Order Code / Article Number, quantity and destination country. State motor or transformer duty, nameplate current/voltage, starting or inrush conditions, available short-circuit current, terminal preference and required accessories. For an existing assembly, add markings, photos and wiring details.
