Tender specification sheets

Long specification
Base element can take a protected plug for up to four floating-ground powered paired cables. When the base unit is fitted, a simultaneous electrically conducting contact is made between the mounting rail (earth) and the reference potential (ground) of the protection circuit in the plug. With optional remote monitoring. Mechanical coding of the base element to the protected plug according to switching type and rated voltage. The base unit is coded itself by the first insertion of a protected plug. Possible to mark all terminals  
Short specification
Base element receives a protected plug for up to four floating-ground powered paired cables with direct earthing. With optional remote monitoring.
