pl5 – transparent cover for 4mm terminals

Why Choose the TE Connectivity PL5 Transparent Safety Cover?

The TE Connectivity PL5 (1SNK900618R0000) is a transparent safety cover designed for compatible ENTRELEC SNK screw-clamp terminal blocks. This insulating accessory covers the screw-clamp area to help prevent direct access while retaining clear visibility of the terminal assembly beneath the cover.

Designed for terminal blocks with 5.2 mm spacing, including compatible 4 mm² ZS4 Series terminals, the PL5 provides a simple way to improve protection around terminal connections. Its transparent construction also allows covered circuits and terminal identification to remain visible during inspection and maintenance.

The PL5 is manufactured from clear polycarbonate and measures approximately 49.24 mm high and 25.05 mm deep, with a weight of only 1.5 g. It carries an IP20 protection rating, a UL 94V-2 flammability rating and an operating temperature range of -55 to +110 °C, making it suitable for professional industrial panel applications.

Key Advantages

• Protective safety cover helps prevent access to screw clamps on compatible terminal blocks.
• Transparent construction maintains visibility of the covered terminal assembly.
• Designed for compatible 5.2 mm spacing screw-clamp terminals.
• Suitable for compatible ZS4 Series 4 mm² terminal blocks.
• Can be used to help identify and protect live circuits within terminal assemblies.
• Durable polycarbonate construction provides a lightweight insulating barrier.
• Wide -55 to +110 °C operating temperature range supports demanding industrial environments.

Reliable Protection for Screw-Clamp Terminal Assemblies

The PL5 provides an insulating cover over the screw-clamp area of compatible terminal blocks, helping restrict access to connection points once the terminal assembly has been installed. This is particularly useful where additional visual and physical separation of selected terminal positions is required within an industrial control panel.

Its clear polycarbonate construction means protection can be added without obscuring the underlying terminal assembly. Combined with its compact 5.2 mm spacing, IP20 rating and broad operating temperature range, the PL5 provides a practical accessory for maintaining organised and protected ENTRELEC SNK screw-clamp terminal installations.

Typical Applications

• Protecting screw clamps on compatible terminal blocks.
• Covering selected live terminal circuits.
• Industrial control panels and automation cabinets.
• ZS4 Series terminal block assemblies.
• Switchgear and electrical distribution panels.
• Machine building and OEM electrical systems.
• PLC, process control and motor control cabinets.
