The TE Connectivity ES4-SF 1SNK508960R0000 is a dark grey insulating end section cover designed for use with compatible ENTRELEC SNK screw clamp terminal blocks. Specifically suited to fuse and disconnect terminal assemblies, it provides the insulating closure required at the end of a terminal group, helping create a safe, organised and professional DIN rail installation.
Manufactured from durable polyamide, the ES4-SF is designed to complement compatible 4 mm² ZS4-series fuse and disconnect terminal blocks. Its slim 1.5 mm profile adds minimal width to the terminal assembly while covering the exposed side of the final terminal and maintaining the required insulating separation.
The ES4-SF measures 59 mm high and 31.9 mm deep, with an operating temperature range of -55–110 °C. Its IP20 protection classification and UL 94V-0 flammability-rated polyamide construction make it a practical accessory for industrial control panels, automation equipment and machinery using compatible ENTRELEC SNK screw clamp terminals.
End section covers are used to close the exposed side of a terminal block at the end of a DIN rail assembly. Because many modular terminal blocks have an open-sided construction, the correct end plate helps maintain insulation, provides a finished boundary for the terminal group and contributes to an organised panel layout without requiring another complete terminal block.
At only 1.5 mm wide, the ES4-SF provides this insulating closure while adding minimal space to the assembly. Its dark grey polyamide construction is specifically designed to complement compatible ENTRELEC SNK fuse and disconnect screw clamp terminals, making it an important finishing accessory for professional control panel and machinery wiring.

The ES4-SF is an insulating end section cover used to close the exposed side of compatible ENTRELEC SNK screw clamp terminal blocks, particularly compatible ZS4-series fuse and disconnect terminal assemblies.
No. The ES4-SF is an end plate / end section cover rather than an electrical terminal. It is installed alongside compatible fuse or disconnect terminal blocks to provide insulation and a finished end to the terminal assembly.
The ES4-SF is manufactured from dark grey polyamide and has a UL 94V-0 flammability rating, making it suitable for use in industrial electrical assemblies.
The ES4-SF measures approximately 59 mm high, 31.9 mm deep and 1.5 mm wide, with a product weight of approximately 1.8 g.
The ES4-SF has an operating temperature range of -55–110 °C and an installation temperature range of -5–40 °C.
TE Connectivity ENTRELEC SNK terminal block accessories help panel builders, automation engineers and machine manufacturers complete modular terminal assemblies with reliable insulation, protection and a professional finish for demanding industrial electrical installations.
