Product details

Overview

It mounts via a plug-in front face onto a compatible power base (LUB32, LUB38, LUB320, LUB380) and carries an IP20 enclosure rating. Manual reset is standard, and the unit provides overload, short-circuit, earth fault, and phase-failure protection.

Compliance & certifications

The LUCC18B holds CE, UL, CSA, CCC, EAC, ASEFA, ATEX, and Marine certifications, and complies with EN 60947-6-2, IEC 60947-6-2, UL 60947-4-1, and CSA C22.2 No 60947-4-1 (with phase barrier). These marks cover the majority of global panel acceptance requirements for industrial and hazardous-location installations.
