ESSAILEC sockets for voltage transformers - Break before make
Description
Opened type contacts for measurement and calibration applications.

Break before make principle:
• The connection is made thanks to the lid: the removing of the lid opens the circuit. So the device is isolated
from power supply to be tested.
• The circuit is closed only when the lid is reinstalled.
• By convention, grey coding is for voltage circuits blue coding is for polarity circuits and orange coding is for
