TeSys F Electromagnetic Switching Characteristics

The LC1F115 uses a mechanically actuated contact system controlled by a separately selected coil assembly. The main power poles provide three normally open contacts for switching motor and resistive loads. The coil drawer design permits installation of LX series coils and replacement without changing the main contactor body.

The contact path is rated for AC-3 motor duty with a 115 A operational current at 440 V AC. The contactor supports AC-1, AC-3, and AC-4 utilization categories according to IEC 60947-4-1. Power connections are provided through bolted terminals for bars, cables with lugs, or dedicated connectors.

Frequently Asked Questions

Q: Can the LC1F115 operate without an installed coil?
A: No. The LC1F115 is supplied as a contactor body without a coil. A compatible coil must be selected and installed before electromagnetic operation.

Q: What control circuit voltage ranges can be used with LC1F115 coils?
A: The compatible LX coil options support different AC and DC control voltage ranges, including 24 to 575 V AC, 24 to 460 V DC, and other specified LXE coil ranges.

Q: What are the main connection requirements for the power circuit?
A: The power circuit supports bolted connections using lugs, connectors, or bars. Terminal selection must match the installed conductor type and application requirements.

Field Installation Guidelines

Install the LC1F115 on a rigid mounting plate with sufficient clearance for power connections, coil access, and accessory installation. Verify that the selected coil voltage matches the control supply before energizing the contactor.

Power conductors should be routed separately from sensitive control wiring where required. Cable shielding and grounding practices should follow the installation requirements of the connected control system. Terminal tightening must follow the specified torque values to maintain electrical contact integrity.

For motor circuits, confirm upstream protection coordination, conductor sizing, and short-circuit protection ratings before commissioning. The contactor should be installed in an enclosure suitable for the surrounding environmental conditions.
