The ABB MS132-2.5 1SAM350000R1007 is a compact, entry-level industrial manual motor starter engineered for simple control, overload protection, and short-circuit prevention of small AC motors—specifically optimized for low-power applications requiring ease of use, space efficiency, and basic safety (e.g., small fans, pumps, laboratory equipment, and household appliances in commercial, residential, and light industrial settings). It functions as an "all-in-one small motor manager," combining manual on/off control with thermal overload protection and magnetic short-circuit tripping, eliminating the need for separate breakers and relays. Designed to comply with global electrical standards and fit tight installation spaces, it balances simplicity, affordability, and reliability for low-current motor applications. Below is its detailed specification:

| Protection Features | - Overload Protection: Class 10 thermal protection (trips within 10s at 6× rated current)
- Short-Circuit Protection: Magnetic tripping (10×~14× rated current, instantaneous)
- Reset Type: Manual reset (prevents automatic restart after faults)
- Auxiliary Contacts: 1 Normally Open (NO) + 1 Normally Closed (NC) (2A, 250V AC) | Class 10 protection matches small motor thermal characteristics; magnetic tripping safeguards against wire insulation failure |
- Mechanical & Operational Specifications:
- Mounting Type: 35mm DIN rail (EN 50022)
- Housing Material: Flame-retardant thermoplastic (UL 94 V0)
- Operating Mechanism: Toggle switch (on/off/reset positions)
- Weight: Approximately 60g | Ultra-narrow 22.5mm width enables dense mounting (up to 17 units per meter of DIN rail); compact size fits in mini control cabinets |
| Environmental Ratings | - Operating Temperature Range: -25℃~+60℃ (-13℉~140℉)
- Storage Temperature Range: -40℃~+85℃ (-40℉~185℉)
- Humidity Tolerance: 5%~95% RH (non-condensing, 40℃)
- Vibration Resistance: 10~500Hz, 1g acceleration (IEC 60068-2-6)
- Shock Resistance: 20g (11ms half-sine, IEC 60068-2-27)
- EMC Compliance: EN 61000-6-2 (immunity: Level 2) | Wide temperature range suits indoor commercial/residential environments; vibration tolerance prevents accidental tripping near small machinery |
- Compliance Standards: CE, UL 508, CSA C22.2 No.14, IEC 60947-4-1, RoHS |
- Ultra-Compact Design: 22.5mm width (1/5 the size of standard starters)—fits in space-constrained locations (e.g., mini control panels for laboratory equipment, under-counter appliance enclosures) and enables dense DIN rail mounting, saving cabinet space.
- All-in-One Functionality: Combines manual control, Class 10 overload protection, and magnetic short-circuit protection—eliminates the need for separate circuit breakers and overload relays, reducing system cost and complexity for small motor applications.
- Adjustable Current Range: 0.6A~2.5A dial-adjustable rated current—accommodates multiple small motor sizes (e.g., 0.6A for 0.25kW pumps, 2.5A for 1.1kW fans), simplifying inventory for facilities with diverse low-power machinery.
- Manual Reset Safety: Requires manual intervention after tripping—prevents automatic restart of motors after faults (e.g., fan jams, pump blockages), enhancing operator safety and avoiding unexpected equipment activation in residential/commercial settings.
- Built-In Auxiliary Contacts: 1NO+1NC contacts (2A, 250V AC)—enable basic status feedback (e.g., "motor running" LEDs) or interlock control (e.g., stopping a pump if a tank is empty) without additional modules, supporting simple control logic.
- Flame-Retardant Housing: UL 94 V0 thermoplastic—meets strict fire safety standards for electrical enclosures, critical for residential (e.g., household pumps) and commercial (e.g., office HVAC) applications where fire risk must be minimized.
- Easy Installation: Tool-less DIN rail mounting and push-in wire terminals—enables fast setup (3 minutes per unit) by electricians or maintenance staff, reducing installation time for small motor systems (e.g., retail display coolers).
- Commercial & Residential Appliances: Small motor control:
- HVAC Auxiliaries: Controls small fan motors (e.g., 0.37kW bathroom exhaust fans, 0.75kW air purifiers)—compact size fits in wall-mounted fan enclosures; manual reset prevents restart after power outages.
- Household Pumps: Manages 0.25kW~0.55kW water circulation pumps (e.g., boiler circulators, aquarium pumps)—adjustable current range fits diverse pump models; flame-retardant housing meets residential electrical safety standards.
- Light Industrial & Laboratory Equipment: Precision small-motor control:
- Laboratory Machinery: Controls 0.55kW~1.1kW motors for centrifuges, stirrers, and small mixers—narrow width fits in bench-top equipment enclosures; auxiliary contacts trigger "equipment on" indicators for lab safety.
- Printing & Packaging Auxiliaries: Manages 0.75kW~1.1kW motors for label dispensers and small conveyor belts—EMC immunity resists interference from nearby printers; vibration tolerance ensures reliable operation in busy workshops.
- Retail & Office Equipment: Light-duty motor management:
- Retail Display Coolers: Controls 0.37kW~0.55kW compressor fans—manual reset avoids automatic restart after cleaning cycles; compact size fits in under-counter cooler control panels.
- Office Equipment: Manages 0.25kW~0.37kW motors for shredders, laminators, and small air conditioners—adjustable current range matches equipment power ratings; flame-retardant housing enhances office safety.
- Agriculture & Hobby Applications: Small-scale motor control:
- Hydroponic Systems: Controls 0.25kW~0.55kW water pumps and air blowers—wide humidity tolerance (5%~95% RH) suits damp growing environments; manual reset prevents pump restart after nutrient line clogs.
- Hobby Workshops: Manages 0.55kW~1.1kW motors for small drills, sanders, and lathes—easy toggle operation simplifies use for hobbyists; DIN rail mounting fits in workshop utility panels.
- Motor Compatibility (Critical): Ensure motor power/current matches the starter’s range (0.6A~2.5A, up to 1.1kW/400V)—overloading causes frequent tripping or starter damage; use ABB’s motor-starter sizing tool to verify (refer to the motor nameplate for rated current, not full-load current). Do not use for DC motors (AC-only design).
- Installation & Wiring Safety:
- Current Setting: Adjust the current dial to exactly match the motor’s rated current—setting too high bypasses overload protection (risks motor burnout); setting too low causes nuisance tripping (e.g., during motor startup).
- Wiring Terminals: Use push-in terminals for 0.5mm²~2.5mm² copper conductors—ensure wires are stripped to 8mm length (no exposed conductors); torque screw terminals (if used) to 0.5Nm to prevent loose connections and overheating.
- Grounding: Connect the starter’s PE terminal to a dedicated protective ground (resistance ≤1Ω)—ungrounded installations increase electric shock risk; do not share the ground with non-motor equipment (e.g., lighting, outlets).
- Operation & Maintenance:
- Reset Procedure: After tripping, first identify and fix the fault (e.g., clear a blocked pump, reduce motor load) before resetting—resetting without resolving the issue damages the motor or starter; allow the starter to cool for 3 minutes after thermal tripping.
