Quick guide from the manual
The ABB MS132-0.25K is a compact 45 mm wide manual motor starter designed to manually switch motors on and off. It provides reliable protection against short-circuits, overloads, and phase failures without the need for a fuse. This device is suitable for both three-phase and single-phase applications.
Product Overview
The device features a rotary handle with clear switch position indication (ON/OFF/TRIP) and is lockable to prevent unauthorized changes. It includes a built-in disconnect function and temperature compensation.
Technical Specifications
- Rated Operational Current (Ie): 0.25 A
- Rated Operational Voltage: 690 V AC / 250 V DC
- Rated Service Short-Circuit Breaking Capacity (Ics): 100 kA at 400 VAC
- Trip Class: 10
- Degree of Protection: IP20
- Electrical Durability: 50,000 cycles
- Mechanical Durability: 100,000 cycles
Installation
The device is designed for mounting on a DIN rail. Ensure the following conditions are met:
- Mounting Rail: Compatible with TH35-15 (35 x 15 mm) and TH35-7.5 (35 x 7.5 mm) rails according to IEC 60715.
- Wire Connection: Uses Push-in spring terminals.
- Connecting Capacity: Supports flexible wires with ferrules (0.5 - 4 mm²), solid wires (1 - 2.5 mm²), and stranded wires (1 - 6 mm²).
- Wire Stripping Length: 12 mm.
- Mounting Distances: Maintain specific distances from conductive boards and other devices to ensure proper operation (e.g., 0 mm to 1.5 mm for conductive boards depending on voltage).
Accessories
The MS132-0.25K supports a wide range of accessories, including:
- Auxiliary contacts (e.g., HKF1-11, HK1-20)
- Signaling contacts (e.g., SK1-20, SK1-11)
- Shunt trips (e.g., AA1-24, AA1-230)
- Undervoltage releases (e.g., UA1-24, UA1-230)
- Busbars (e.g., PS1-2-0-65K)
- Enclosures and door mounting kits
Practical help
Common problems
Device fails to switch or trips unexpectedly
Verify that the motor load matches the rated operational current (0.25 A) and check for short-circuits or phase failures in the circuit.
Difficulty mounting on DIN rail
Ensure the rail is a standard TH35-15 or TH35-7.5 type according to IEC 60715.
Before use
- Verify the motor's rated current is within the 0.16 - 0.25 A range.
- Ensure the supply voltage does not exceed 690 V AC.
- Check that the wire size is compatible with the Push-in spring terminals (0.5 - 4 mm² for flexible with ferrule).
- Confirm the DIN rail type is TH35-15 or TH35-7.5.
- Ensure proper clearance distances are maintained from conductive boards.
Specs in practice
- Ie (Rated Operational Current)
- The current the device is designed to handle continuously (0.25 A).
- Ics (Rated Service Short-Circuit Breaking Capacity)
- The maximum fault current the device can interrupt while remaining operational (100 kA at 400 VAC).
- Trip Class 10
- The time-current characteristic defining the tripping time under overload conditions.
Model compatibility
- Compatible with various ABB accessories including auxiliary contacts, signaling contacts, and shunt trips.
- Suitable for both three-phase and single-phase applications.
- Requires terminal spacer TS1-M3-K for UL508 Type E compliance.
