Three-Phase Primary Interlock Switch for ISOVOLT HS
Application
•  Produced under ISO 9001 certified quality management system
A primary interlock switch is used in 
radiation protection cabinets and rooms 
in conjunction with doors and flaps that 
can be opened under regular operative 
conditions, if the power supply of the 
X-ray radiating unit must be interrupted 
in the primary current circuit and if this 
disconnection through an interlock circuit 
must be physically linked to said doors 
and flaps.
The primary interlock switch consists 
of two components which are designed 
in such a way that only one of them 
needs wiring. This component is usually 
mounted to the non movable part of the 
cabinet. The second component of the 
primary interlock switch is attached to 
the door or flap and does not need any 
electrical connections.
The switch is wired in such a way that 
upon opening it directly interrupts the 
primary current circuit of the X-ray 
equipment. An additional internal switch 
is available for status messages to the 
control.
