Product details

Overview

The LUCD18BL: Housed in a 45.72 mm wide, 60.96 mm deep, 66.04 mm high IP20 enclosure, it mounts via plug-in front face and includes an extraction and locking handle, test button, and sealing of the locking handle.

Sizing and selection

The 24 V coil suits control circuits common in PLC-driven panels; the manual reset requires operator intervention after a fault, which is standard for unattended machinery where automatic restart is not permitted.

The LUCD18BL carries IEC 60947-6-2, UL 60947-4-1 (with phase barrier), and CSA C22.2 No 60947-4-1 (with phase barrier) certifications, plus UL 508 and CSA C22-2. It is in active production; an RFQ confirms current lead time.
