OV Category Application Data
SCS controls are designed for use in applications
where the equipment is connected to the AC supply
using a plug and socket (OV Category II applications).
When applying the SCS controls in permanent wired
equipment (OV Category III applications), a 1A inline
fuse and MOV are required.
• Fuse 1A Littlefuse Type 3AG Slo-Blo
®
or similar.
• MOV 300V Littlefuse V300LA20AP or similar.
