LC1DT25F7 - Telemecanique Contactor

LC1DT25F7  - Telemecanique Contactor

The LC1DT25F7 is a TeSys Deca contactor built for resistive and non-inductive loads, with four normally open power contacts and a 25A AC-1 rating at up to 440VAC at temperatures below 60°C. It uses a 110VAC 50/60Hz coil and already includes 1NO + 1NC auxiliary contacts. That's useful when you're trying to match a contact already in a panel—you can compare the coil, contacts, terminals, and footprint without relying on the catalog number alone. Connections are made through screw-clamp terminals, and the contactor can be mounted on a rail or plate.

Material Compliance and Certifications

Plenty of documented compliance information is available for the LC1DT25F7, so there's no need to make assumptions. The manufacturer identifies the product as Green Premium compliant, including RoHS and REACH compliance.

Where It Works Best

The LC1DT25F7 makes sense for equipment that calls for a 4-pole, 4NO AC-1 contactor handling resistive or other non-inductive loads within its stated ratings. The 110VAC coil is one of the first things worth confirming because a contactor with the right current rating but the wrong coil voltage isn't the right match.

After that, compare the contact arrangement and auxiliary contacts. This model has four normally open power contacts plus 1 NO and 1 NC auxiliary contacts. Check the screw-clamp connections as well.
