LC1-DT40 25A 4 Pole AC Contactor

The GOTOELE LC1-DT40 25A 4 Pole AC Contactor is a compact low-voltage switching device designed for applications requiring multiple controlled circuits within limited cabinet space.

Compared with conventional 3-pole contactors, the four-pole configuration provides an additional contact path, allowing engineers to control auxiliary circuits, power distribution lines, and electrical loads with greater flexibility. This makes it especially suitable for automation machines, control panels, HVAC equipment, packaging machinery, and customized OEM electrical systems.

The contactor supports AC applications up to 660V and 50/60Hz frequency conditions. Combined with thermal overload relays, auxiliary contacts, and timer modules, it can build complete motor control and electrical switching solutions according to different equipment requirements.

4 Pole Contactor vs Traditional 3 Pole Contactor

In many industrial control systems, 3-pole contactors are mainly selected for standard three-phase motor switching. However, some applications require simultaneous control of additional circuits, neutral switching, or auxiliary power paths.

The LC1-DT40 25A 4 Pole AC Contactor provides four independent normally open contacts, offering several advantages:

· More flexible circuit configuration compared with standard 3-pole models.

· Better suitability for machines requiring separate auxiliary power switching.

· Reduced installation space by integrating multiple switching functions into one component.

· Easier maintenance for OEM control cabinet builders.

For equipment manufacturers designing compact electrical cabinets, this structure helps simplify wiring and improve overall system integration efficiency.
