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.
