Industrial Motor Starter

The Schneider Electric SQUARE D LC1D80BD is a three-pole IEC magnetic contactor designed for non-reversing motor control and resistive load switching in industrial panels. It operates on a 24V DC coil and provides one normally open and one normally closed auxiliary contact for circuit logic. The unit mounts on DIN rail or plate without an enclosure.

Screw Clamp Terminals and Auxiliary Contacts

The screw clamp terminals accept standard wiring for power and control circuits without specialised tools. The 1NO/1NC auxiliary block enables immediate feedback to a PLC or relay logic, supporting interlocking or status indication in the same footprint. No extra accessories are required for basic installation.

Coil Voltage and Temperature Limits

The contactor drops out between 0.1 and 0.3 times rated coil voltage and operates up to 1.1 times rated voltage within a 55 to 70°C ambient range. Electrical durability is rated at 800000 cycles under defined conditions. It handles 80 A inductive and 125 A resistive loads with horsepower ratings up to 60 hp at 600V AC three-phase.

Questions about this item

How often will the auxiliary contacts on this 24V DC contactor need replacement?

Electrical durability is rated at 800000 cycles under specified conditions, so replacement timing depends on your actual switching frequency and load type.

What limits continuous operation of this 80 A inductive-rated contactor?

The coil must stay within 0.1 to 0.3 Uc for drop-out and up to 1.1 Uc for operation at 55 to 70 °C ambient, while the main contacts are rated 80 A inductive and 125 A resistive.

How much heat does this three-pole contactor produce when running all day?

The coil operates at 24V DC with drop-out between 0.1 and 0.3 Uc and continuous operation up to 1.1 Uc at 55 to 70 °C ambient; the open-frame design relies on natural convection inside the enclosure.
