Product details

The LC4D65B7 is a direct-on-line (DOL) starter from the TeSys LC4 series, combining a contactor and a fuse disconnector in one unit. It is rated for AC-3 duty at 65 A, which means it handles the high inrush of squirrel-cage motors during starting — the AC-3 category is the standard for motor switching under IEC 60947-4-1. At 380–400 V AC it drives a 30 kW motor; at 415 V that rises to 37 kW, and the same 37 kW holds at 440 V, 500 V, and 660–690 V. At 220–230 V the rating drops to 18.5 kW. The coil is 24 V AC, so it integrates into standard control-voltage circuits without a separate transformer.

This starter mounts to a plate — no DIN-rail clip. The footprint is 281 mm wide by 143 mm tall by 130 mm deep, so plan for a backplate or sub-panel that accommodates those dimensions. The contactor and fuse disconnector are factory-assembled, which saves panel-building time compared to wiring separate components.

Frequently asked questions

What is the price of LC4D65B7?

Pricing for the LC4D65B7 is confirmed at quote time against an RFQ. Submit a request for current market pricing.

Is LC4D65B7 available via RFQ confirmation?

Availability is confirmed at quote time. Submit an RFQ to check current stock position and lead time.

What is a DOL starter used for?

A DOL starter directly connects a motor to the supply line, providing overcurrent protection via the integrated fuse disconnector and switching via the contactor. It is the simplest motor starting method, suitable for fixed-speed applications like pumps, fans, and conveyors where the motor's starting current does not cause issues.

What size contactor for a 30 kW motor?

For a 30 kW motor at 380–400 V AC, the LC4D65B7 with its 65 A AC-3 rating is correctly sized. At 415 V the same unit supports up to 37 kW.

What is the difference between LC4D65B7 and LC4D65B6?

The difference is the coil voltage: LC4D65B7 has a 24 V AC coil, while the LC4D65B6 uses a different coil voltage. All other ratings (65 A, AC-3, motor power) are identical.
