1sna116515r0000 – cover cpu42 (power blocks)

Why Choose the TE Connectivity 1SNA116515R0000 CPU42 Protective Cover?

The TE Connectivity 1SNA116515R0000, also identified as CPU42, is a purpose-designed protective cover for Entrelec power terminal blocks. Part of the established TE Connectivity / Entrelec SNA screw-terminal accessory range, it provides an insulating barrier for compatible power-block connections in industrial control panels, switchgear and electrical distribution assemblies.

Manufactured from grey plastic, the CPU42 is designed to cover exposed areas of compatible power terminals, helping reduce the risk of accidental contact while maintaining an organised terminal assembly. Its snap-on construction provides straightforward fitting as part of a compatible SNA power-block installation.

The CPU42 is specified for a 2-pole arrangement and is associated with compatible power terminal blocks requiring the larger CPU42 cover format. With a net weight of approximately 125 g and compatibility with SNA assemblies mounted on G32 and TH35 DIN rails, the 1SNA116515R0000 provides a dedicated protective accessory for professional industrial panel construction.

Purpose-Designed Protection for Industrial Power Blocks

Power terminal blocks can contain substantial conductors and accessible connection hardware, making suitable protective accessories important when completing an industrial terminal assembly. The CPU42 provides a dedicated insulating cover for compatible power blocks, helping shield the connection area from inadvertent contact while preserving access when maintenance is required.

Unlike a generic enclosure or barrier, the 1SNA116515R0000 is designed specifically as part of the Entrelec terminal system. Its 2-pole format, snap-on construction and insulating plastic body make it a practical accessory for completing compatible power-distribution, switchgear and industrial control-panel installations.

Typical Applications

• Industrial electrical control panels.
• Compatible Entrelec power terminal blocks.
• Power-distribution assemblies.
• Industrial switchgear.
• Machine-control cabinets.
• Automation equipment and electrical panels.
• OEM panel building and maintenance.
