DIL3M80

What is this contactor used for?

This contactor is used for switching and controlling industrial power circuits, particularly motor loads. It is commonly selected for motor starters, pump panels, fan systems, compressors and conveyor applications where a robust electromechanical switching device is needed.

What current and motor size range is it generally suited to?

This model sits in the 100 to 160 amp class and is commonly associated with approximately 30 to 50 hp motor applications, depending on the supply system and duty requirements of the installation.

Is it suitable for three-phase motor control?

Yes. The unit is designed for use in three-phase control arrangements and is well suited to mains switching duties in motor control panels. The DIL3M80 is often used where dependable switching of higher-current motor circuits is required.

Can it be used in reversing or star-delta starter arrangements?

Yes. This frame size is commonly used in reversing and star-delta style assemblies when combined with the appropriate associated components, such as interlocks and timing devices, where the panel design calls for that arrangement.

How is it mounted?

The published mounting arrangement shows screw fixing with 2 x M5 x 20 screws. The mounting dimensions shown for this unit are approximately 80 mm and 110 mm for the referenced fixing layout, and the permitted mounting position is shown within a 30 degree inclination.

What conductor sizes can the terminals accept?

Terminal capacity depends on conductor type and termination method. Published connection data for this size includes conductor ranges such as 6 to 16 mm², 4 to 50 mm² and up to 16 to 70 mm², with a stated tightening torque of 6 Nm for the relevant terminal arrangement.

Can auxiliary contacts be added?

Yes. Side-mounted auxiliary contact blocks are available for this contactor family. Depending on the exact configuration, auxiliary modules can be fitted to expand signalling and control functions for status indication, interlocking and control circuit feedback.

Can it be mechanically interlocked with another contactor?

Yes. Mechanical interlock accessories are available for this frame size to create paired contactor assemblies, typically for forward and reverse motor control arrangements. When using a mechanical interlock, the final layout should be checked carefully because accessory placement can affect how auxiliary blocks are fitted.

What should be checked before selecting this contactor for a replacement job?

It is important to confirm the coil rating and control voltage version, required auxiliary contacts, terminal capacity, mounting footprint and the electrical duty of the application. Matching the existing panel layout and control scheme is especially important when replacing an older installed unit.

Is this a good choice for older panel refurbishments?

Yes, it can be a practical option for refurbishment or like-for-like replacement work in existing industrial control panels, especially where the original design already uses this style and size of contactor. The DIL3M80 is particularly relevant where maintaining a familiar mounting and wiring approach is helpful.
