LC1D09M7

What is this contactor used for?

This contactor is designed for switching and controlling electrical power circuits, particularly in motor control applications. It is well suited to panel builders and maintenance teams looking for a compact 3-pole device for AC motor duties and resistive loads.

Is this suitable for motor control applications?

Yes. It is intended for motor control and is rated for AC-3 and AC-3e duties, making it a practical choice for starting and switching three-phase motors within its electrical ratings.

What are the main electrical ratings?

The unit is rated at 9 A for AC-3 duty at up to 440 V AC and 25 A for AC-1 duty at up to 440 V AC. The power circuit is rated for up to 690 V AC and up to 300 V DC, depending on the application.

What coil voltage does it require?

This version uses a 220 V AC 50/60 Hz coil. If you are matching an existing panel design, the LC1D09M7 should be checked against the control voltage already present in the circuit.

How many main poles does it have?

It has 3 main poles with 3 normally open main contacts. This makes it suitable for switching three-phase loads in a straightforward non-reversing arrangement.

Does it include auxiliary contacts?

Yes. It includes 1 normally open and 1 normally closed auxiliary contact as standard. These can be useful for interlocking, status indication or basic control logic within a panel.

Can it be used for resistive loads as well as motors?

Yes. In addition to motor control, it can also be used for resistive loads. Its AC-1 rating of 25 A makes it suitable for applications where the load characteristics are less demanding than motor starting.

What motor sizes is it typically used with?

Typical motor power ratings include 2.2 kW at 220 to 230 V AC, 4 kW at 380 to 440 V AC, and 5.5 kW at 500 to 690 V AC under AC-3 duty. Actual suitability should always be checked against the full application conditions.

What type of terminals does it use?

It uses screw clamp terminals for both power and control wiring. This suits many conventional panel wiring layouts and allows connection of solid or flexible conductors within the stated cable size ranges.

How is it mounted?

This contactor can be mounted on a plate or on DIN rail, giving flexibility for new builds and replacement work in existing control panels.

What are the physical dimensions?

The contactor is compact, with approximate dimensions of 77 mm high, 45 mm wide and 86 mm deep. Its net weight is around 0.32 kg, which helps when space is limited inside the enclosure.

Does it have a built-in suppressor module?

No. This model does not include a built-in suppressor module as standard, so that should be considered if the application calls for additional control circuit noise suppression.

What is the front protection rating?

The front face has an IP20 protection rating. This means it is intended for installation inside a suitable enclosure or electrical assembly rather than exposed use.

What operating temperatures can it handle?

It is designed to operate in ambient temperatures from -40 °C to 60 °C, with derating up to 70 °C. This makes it suitable for a wide range of industrial environments when installed correctly.

Is it suitable for frequent switching?

Yes. It has a maximum operating rate of up to 3600 cycles per hour at under 60 °C, making it a good fit for applications that involve regular switching within the stated duty limits.
