Description
Short-circuited type contacts for measurement, calibration and distribution applications.
Make before break principle:
• The circuit is automatically shorted with the insertion of the plug.
• The circuit closes automatically when the plug is removed.
• This system guarantees a complete safety.
• By convention, green coding is for current circuit.
