## Summary description

EATON motor protection circuit breaker, 3-pole, adjustable current range 25–32 A, rated for 15 kW motor protection (MPN 189870). Designed to protect electric motors from overloads and short circuits, it provides adjustable thermal-magnetic tripping and manual on/off control. Suitable for industrial motor starters, pump and conveyor protection, and maintenance panels.

## Long description

EATON motor protection circuit breaker, 3-pole device with an adjustable current range of 25–32 A, rated for protecting motors up to 15 kW. The unit integrates thermal-magnetic tripping elements and a manual on/off control to isolate and protect three-phase electric motors from overload and short-circuit conditions. Designed for installation in motor starter assemblies, control panels and industrial switchboards, this breaker offers selectable trip adjustment for coordination with motor full-load currents and thermal protection requirements.
Advantages
The breaker provides combined thermal and magnetic protection in a single compact 3-pole housing, enabling reliable detection of overloads and short-circuits. The adjustable current setting (25–32 A) allows precise adaptation to motor characteristics, helping to reduce nuisance trips while maintaining safety. Manual on/off control simplifies local operation and maintenance, and the design supports integration into standard motor starters and control circuits.
Suitable for
 Protection of three-phase motors in industrial applications
 Pump and conveyor motor protection
 Motor starter and contactor assemblies
 Maintenance and control panels requiring adjustable motor protection
Key specifications
 Poles: 3-pole configuration for three-phase systems
 Adjustable current range: 25–32 A
 Motor power rating: suitable for motors up to 15 kW
 Protection type: thermal-magnetic tripping (combined overload and short-circuit protection)
 Control: manual on/off operation
 Mounting: intended for panel or motor starter installation
How to use
Install the breaker in the motor starter or control panel following local electrical codes and the manufacturer’s mounting recommendations. Connect the three-phase supply and motor conductors to the appropriate terminals, verify tightness of connections, and set the adjustable current dial within the 25–32 A range to match the motor’s required full-load current. Perform insulation and continuity tests before energising. Use the manual on/off control for local disconnection during commissioning and maintenance. Ensure correct coordination with upstream and downstream protective devices to maintain selective protection.
Usage recommendations
For reliable operation, set the breaker’s current adjustment to the motor nameplate full-load current or to the value advised by the control design, and verify thermal trip coordination with ambient temperature and expected duty cycle. Periodically inspect connections and test tripping operation as part of routine maintenance. Replace the device if mechanical operation becomes stiff or if repeated nuisance trips indicate possible internal degradation.
