## Summary description

EATON motor protection switch, three-pole (3P), rated for 1.5 kW motors with adjustable current setting 2.5–4 A (model 189901). Designed to protect motors from overload and phase faults, it provides thermal/magnetic trip characteristics, manual operation and selectable trip range. Suitable for industrial and workshop motor control and protection applications.

## Long description

The EATON motor protection switch 3P for 1.5 kW motors features an adjustable thermal/magnetic trip range of 2.5–4 A and manual operation for reliable motor protection. Intended for use in motor control circuits, this three-pole device detects overloads and phase faults, isolating the motor circuit when trip conditions occur. The unit is designed for industrial and workshop environments where compact, selectable protection is needed for smaller motors.
Advantages
This motor protection switch combines thermal and magnetic tripping to protect against sustained overloads and short-circuit conditions while allowing adjustable current setting to match the motor full-load current. Manual operation provides straightforward isolation and reset, and three-pole construction ensures all phases are monitored and interrupted simultaneously. The device is engineered for durability in control panels and motor starters, providing precise, repeatable trip behavior.
Suitable for
Protection of single motors up to 1.5 kW in industrial machinery and workshop equipment
Motor starters and control panels requiring adjustable overload protection
Applications where phase failure or imbalance detection is required
Retrofit projects replacing older, non-adjustable motor protection devices
Key specifications
Poles: three-pole (3P) configuration for three-phase motors
Rated motor power: suitable for motors up to 1.5 kW
Adjustable current range: 2.5–4 A thermal trip setting
Trip type: combined thermal and magnetic tripping for overload and short-circuit protection
Operation: manual control for ON/OFF and reset
Mounting: panel or DIN-rail compatible control panel installation (industry standard footprint)
How to use
Install the switch in the motor control panel following applicable electrical standards and wiring diagrams. Set the adjustable current dial or selector to the motor’s rated full-load current within the 2.5–4 A range. Wire the three-phase supply and motor conductors to the corresponding terminals, ensuring secure connections and correct phase sequence. After installation, perform an insulation and continuity check, then energize the circuit and verify correct operation by starting the motor and observing that the switch does not trip under normal load. Use the manual control to isolate or reset the motor circuit when needed.
Usage recommendations
Use this protection switch with motors whose full-load current falls within the adjustable range, and coordinate settings with upstream protection devices. Periodically inspect terminal connections for tightness, and test tripping behavior during maintenance to ensure reliable protection against overloads and phase faults.
