Why Choose the TE Connectivity CPP311 1SNA168204R1500 Protective Cover?
The TE Connectivity CPP311 1SNA168204R1500, also referenced as COVER 311P 1 BLOCK, is a transparent protective cover for Entrelec SNA power terminal blocks. Designed to cover a single compatible terminal block, the CPP311 provides a physical barrier over the terminal connection while retaining visibility for inspection and maintenance.
As part of the established TE Connectivity Entrelec SNA accessory range, the CPP311 is designed for compatible M70/31 series power terminal blocks with 31 mm spacing. Its transparent construction allows engineers to inspect the terminal and connection without removing the cover, making it particularly useful in industrial control panels, power distribution cabinets and switchgear assemblies.
The CPP311 is designed to cover one terminal block and is installed in conjunction with an ECP31 cover support. The cover snaps onto the supporting partition, which increases the assembly spacing by approximately 1.5 mm. With a net product weight of approximately 7 g, it provides a lightweight, purpose-designed protective solution for compatible high-current terminal assemblies.

Reliable Protection for Power Terminal Connections
Protective covers provide a physical barrier over exposed terminal connections within industrial electrical assemblies. The transparent TE Connectivity CPP311 allows the connection beneath the cover to remain visible, helping engineers carry out routine visual inspections while maintaining a purpose-designed protective arrangement around the terminal.
When installed with the appropriate ECP31 cover support, the CPP311 snaps onto the supporting partition above a compatible 31 mm terminal block. This makes it particularly useful in control cabinets, distribution panels and switchgear where power terminal connections require additional protection while remaining accessible for inspection and maintenance.
Typical Applications
- Industrial electrical control panels.
- Power distribution cabinets.
- Switchgear assemblies.
- Compatible M70/31 power terminal installations.
- Industrial machinery and automation panels.
- Energy and process industry electrical systems.
- Electrical distribution and power connection equipment.
- OEM panel building and machine construction.
