Industrial motor control contactor

The Schneider Electric LC1D18B7 is a three-pole TeSys Deca contactor rated at 18A for AC-3 motor loads up to 690V. It targets panel builders and maintenance engineers who need reliable switching for pumps, fans or conveyors in commercial and light-industrial installations.

45mm DIN-rail unit with screw clamp wiring

The compact 45mm-wide housing mounts on standard DIN rail or via screw fixing, leaving more room in crowded enclosures. Screw clamp terminals accept power and auxiliary cables without special tools, while the built-in 1NO plus 1NC mirror-certified auxiliary contacts free up space that separate contact blocks would occupy.

3600 cycles per hour at up to 60°C

The contactor sustains operating rates of 3600 cycles per hour in ambient temperatures up to 60°C without derating. Its 24V AC 50/60Hz coil maintains consistent pull-in and drop-out behaviour during long duty cycles, and the multi-standard certification supports high short-circuit ratings when paired with approved breakers or fuses.

Questions about this item

What is the maximum operating rate before thermal limits are reached?

The contactor is rated for up to 3600 cycles per hour under normal conditions.

How much heat does the coil generate during continuous 24V AC operation?

The 24V 50/60Hz AC coil is designed for sustained duty in environments up to 60°C.

Which motor protection devices are required to achieve the published short-circuit ratings?

An 85kA SCCR requires a 480VAC 60A circuit breaker; a 100kA SCCR requires a 600VAC 40A Class J or CC fuse.
