The 45 mm width is a key panel-fit spec: it occupies a single 45 mm DIN-rail module, matching the footprint of the ABB MS116 series and most IEC motor starter components. If you're swapping an existing MS116-1.0 (10 A max) for a higher-current motor, the MS132-20 drops into the same slot without re-drilling the panel or moving the rail. ## Protection logic and what it covers The MS132-20 integrates short-circuit protection and phase-failure detection into the same 45 mm housing. Phase-failure detection means the protector opens all three poles if one phase drops out — a common cause of single-phasing damage in delta-connected motors. This is a step above basic thermal-magnetic protectors that only respond to overload current. Rated at 600 V, it covers 480 V and 600 V nominal systems common in North American industrial panels, as well as 400 V IEC installations. The 16–20 A FLA range suits motors in the 5–10 HP range at 460 V, or 7.5–15 HP at 230 V — typical for pumps, small conveyors, and fans.","metaTitle":"ABB MS132-20 Manual Motor Protector, 20 A, 3-Phase","metaDescription":"ABB MS132-20 manual motor protector, 20 A, 3-phase, 16-20 A FLA range, Trip Class 10, 45 mm wide.

This is the full-load ampere setting for the motor it protects — set the dial to match the motor nameplate FLA."},{"question":"Will MS132-20 drop into a panel that was specified around MS116-1.0 without rewiring?","answer":"Yes, the MS132-20 shares the same 45 mm width and DIN-rail mounting as the MS116-1.0. It fits the same panel slot and rail clip. The wiring terminals are in the same positions. The key difference is the current range: the MS116-1.0 maxes out at 10 A, while the MS132-20 covers 16–20 A. If your motor draws more than 10 A FLA, the MS132-20 is a direct drop-in replacement."},{"question":"What compliance documentation does ABB provide for MS132-20?","answer":"ABB supplies the MS132-20 with standard documentation including a datasheet, installation instructions, and declaration of conformity for applicable directives (typically IEC/EN 60947-2 and 60947-4-1). RoHS and REACH compliance statements are available on request. Specific UL/CSA file numbers should be confirmed against the nameplate marking on the unit received."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/abb/MS132-20","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/MS132-20 when reusing this data.
