ESSAILEC sockets for voltage transformers – closed contact

Description
Closed contact principle:
x4
• The electrical connection is continuous. The circuit still closed during the testing operation.
• Closed contacts for measurement and distribution applications.
• By convention, grey coding is for voltage circuits blue coding is for polarity circuits and orange coding is for
trip circuits.
