TE Connectivity PC-DS-VL 1SNA166758R1500 is a blue ESSAILEC screw-clamp voltage transformer test socket with short-circuited contacts, designed for base or half-base mounting in electrical measurement, metering and protection circuits.
Why Choose the TE Connectivity PC-DS-VL ESSAILEC Voltage Test Socket?
The TE Connectivity PC-DS-VL 1SNA166758R1500 is a professional ESSAILEC voltage transformer test socket with short-circuited contacts, designed for measurement, testing and protection circuits in industrial electrical installations. Part of the established TE Connectivity ENTRELEC ESSAILEC range, it provides a dedicated interface for connecting test equipment while helping simplify commissioning, maintenance and diagnostic work.
The PC-DS-VL is a base / half-base mounting socket using reliable screw-clamp connections. Its blue coding identifies the short-circuited-contact configuration within the ESSAILEC voltage transformer range, helping technicians distinguish the appropriate test interface in complex metering and protection installations.
Designed around the ESSAILEC voltage transformer platform, the PC-DS-VL supports circuits rated up to 8 A and features a 25 A for 5 s short-circuit current capability. The system provides IP20 protection without a lid and IP40 with the compatible lid fitted, while the PC-DS-VL has an approximate product weight of 130 g.
