TE Connectivity 1SNA163424R1400 CPP423 is a transparent three-block protective cover for 42 mm spacing ENTRELEC SNA M300/42 power terminal assemblies, designed to snap onto compatible ECP42 partitions.
Why Choose the TE Connectivity CPP423 Protective Cover?
The TE Connectivity CPP423, manufacturer part number 1SNA163424R1400, is a transparent three-block protective cover for ENTRELEC SNA power terminal blocks. Designed for terminals with 42 mm spacing, it provides an additional protective barrier over high-current connections while retaining visibility for inspection and maintenance.
The CPP423 is specifically designed for three adjacent power terminal blocks and fits onto compatible ECP42 partitions. The cover snaps onto the partitions to create a neat protective enclosure around the terminal connections, helping reduce accidental contact while maintaining straightforward access when servicing is required.
This protective cover is suitable for compatible M300/42-series power terminal blocks, including M300/42.AF, M300/42.F and M300/42.FF variants. Its transparent construction, dedicated 42 mm pitch and purpose-designed fit make the CPP423 a practical accessory for high-current industrial power distribution and control-panel assemblies.
