Schneider Electric LUCD18FU Starter Control Unit

Product Description

The SCHNEIDER ELECTRIC LUCD18FU is a starter control unit designed as a direct accessory for compatible motor starter and control systems. This unit manages control-circuit logic within the starter assembly, allowing field technicians to configure or replace the control interface without replacing the entire starter body. It installs in commercial and industrial electrical panels where motor starters are used to manage loads such as pumps, compressors, fans, and conveyor systems. The LUCD18FU measures 4.1 inches in height, 2.1 inches in width, and 3.3 inches in length, and weighs 0.32 pounds, making it a compact, lightweight component suited for tight enclosure environments. Licensed electricians and industrial maintenance technicians are the primary installers.

The LUCD18FU is suited for use in industrial and commercial motor control applications where precise starter logic and control-circuit accessory compatibility are required. It pairs directly with a defined set of Schneider Electric control modules and function blocks, including the LUFC00, LUFDA01, LUFDA10, LUFDH11, LUFN, LUFV2, and LUFW10. These pairings make it relevant in both new-installation and replacement scenarios where a control unit within an existing starter assembly has failed or requires reconfiguration.

Key Features

• Compact form factor at 4.1 x 2.1 x 3.3 inches fits standard industrial enclosures without modification
• Lightweight at 0.32 pounds for easy handling during panel servicing
• Direct compatibility with seven Schneider Electric function block modules: LUFC00, LUFDA01, LUFDA10, LUFDH11, LUFN, LUFV2, and LUFW10
• Single-unit packaging supports one-for-one field replacement without surplus inventory

Compatibility

Designed for use with LUFC00, LUFDA01, LUFDA10, LUFDH11, LUFN, LUFV2, and LUFW10 Schneider Electric motor starter function blocks and control modules.

Installation Notes

Installation should be performed by a licensed electrician familiar with low-voltage motor control wiring and applicable NEC requirements. De-energize the motor starter and verify the absence of voltage at all control-circuit terminals before handling or replacing the control unit. Follow the manufacturer wiring diagrams for the specific function block pairing to ensure correct control-circuit connections. Do not force the unit into position; proper seating with compatible modules is confirmed by mechanical alignment and secure engagement.
