£3.39
The TE Connectivity 1SNA168208R2100, also identified as CPP421, is a transparent protective cover for one M300/42 power terminal block in the Entrelec SNA terminal block range. Designed for terminals with 42 mm spacing, it provides a physical barrier over the connection area while retaining visibility for inspection and maintenance.
The CPP421 is specifically suitable for M300/42.AF, M300/42.F and M300/42.FF power terminal blocks. It is designed to snap onto compatible ECP42 circuit separators, creating a purpose-built protective arrangement for Type I power terminal assemblies in industrial electrical panels.
Manufactured from transparent insulating material, the cover has a thickness of 1.5 mm and a net weight of approximately 13 g. Its single-block format makes it ideal where individual 42 mm power terminals require protection within switchgear, distribution equipment and industrial control installations.
Power terminal accessories help panel builders create organised and protected electrical assemblies. The CPP421 provides a transparent physical cover over a compatible single M300/42 terminal, allowing the connection area to remain visible while reducing direct exposure during normal panel operation.
The cover snaps onto the ECP partition used with compatible Type I power terminals and increases the assembly space by approximately 1.5 mm. CPP421 is the single-block version of the protective-cover family, with related CPP422 and CPP423 versions available for two- and three-block arrangements.
