Introduction

Circuit disconnector boxes are introduced for HL-LHC circuits for the compliance with the electrical safety norms
imposed by CERN (Electrical Safety Code C1). These circuit disconnector boxes will allow the disconnection of the
warm to cold transition in the HL-LHC and will allow to connect the circuits to earth for proper intervention. A
programmable logic controller will allow to monitor the state of the circuit disconnector boxes. In addition, water
cooled and isolated heat sinks are added to this package to limit the heat penetration from the circuit
disconnector systems copper bus bars into the current leads.
