Adjustable Thermal Overload Relay 17-25A

This adjustable thermal overload relay protects motors and circuits from excessive current. It suits industrial electricians and maintenance engineers who need reliable overload protection for three-phase systems operating at standard frequencies. The unit covers a 17 to 25 ampere trip range within the JR28-36 frame size.

DIN rail mounting simplifies installation

The relay clips onto standard DIN rails for quick panel integration. Wiring requires correct torque on power terminals to prevent overheating at the connection points. A common issue is selecting the wrong trip band; verify the motor full-load current falls within the 17 to 25 ampere range before fitting. Incorrect frequency setting for 50 or 60 hertz supply can also cause nuisance tripping.

Questions about this item

How do I confirm the JR28-36 LR2 D23 is protecting a 23 A motor correctly after installation?

Set the dial to 23 A, run the motor at full load, and verify the relay holds without tripping; a sustained overload above 23 A should cause a trip within the thermal curve.

What comes in the box with the JR28-36 LR2 D23 and what must I source separately?

The relay unit itself is supplied; you must provide a compatible contactor, mounting rail, wiring, and any required control-circuit fuses.
