Although the use of grounding resistors is quite consolidated in industrial systems, it is often difficult to identify where a fault has occurred. Even if the fault does not prevent the system from continuing to operate, its quick location allows to eliminate the problem and ensure greater safety.

USC-01C allows this identification without the operator having to interact with powered power panels, meeting the requirements of NR-10. In addition, individual identification units can be provided according to the customer's needs, and the installation of the equipment is extremely simple.

• The research of the place where the phase-earth fault occurred takes place from the current, already limited, that circulates to the earth in the electrical systems that operate in the philosophy of high ohmic value resistors.
• The system is quite simple, consisting only of a microprocessor electronic unit and a toroidal current sensor. The electronic unit signals the
  presence of the fault to ground through a red flashing LED and also the presence of auxiliary voltage through a yellow LED.
• If required by the customer, one or two reversible auxiliary contacts for remote signalling can be supplied on each unit.
• Universal power supply (VCA or VCC)

• Unit USC-01C mounted in ABS plastic housing of dimensions 75x55 mm and DIN rail mounting;
• The system is supplied in a metal enclosure for internal installation (IP40) with dimensions depending on the number of electronic units provided. This enclosure has a display that allows the visualization of the signaling of the units without the need to open the door.
• Toroidal sensors with internal diameter 40 and 90 mm;(*)
