The indicator incorporates a number of fault indicating elements (target) in a casing. For fault in power plants or substation with complicated circuits, it generates alarm and indicates type of the faults by closing the fault circuit.
The indicator monitors fault in complicated circuits concentratedly and makes alarm output contact.
Up to 4 outputs can be connected, eliminating auxiliary relay circuit.
Module type is available in addition to element type. It reduces area requirements of distribution box.
The each indicating elements are Plug-in type, interchangeable, making circuit modification easy and simple.

Size is small, occupying a small space on the switch board and easy to handle.
Incorrect plugging-ins is eliminated for both VT and CT circuits by the device that prevents mistaken plugging-ins. The construction is such that both VT circuit and CT circuit can be tested by the test power source. The main contact is double-contact which assures secure contact. There is no possibility that CT circuit is opened while in use. The contact is of double spring type by the spring of its own and the coil spring, and has high reliability.
This TS Type Test Terminal is used with the test plug mounted on the switch board and make it a simple operation to test and make it a simple operation to test and calibrate matters, relays etc., on the switch board. It construction is small in made by molding and has good appearance. It has excellent electric properties and is most fitted for electric power switch boards. Test terminal and test plug for both VT circuit and CT circuit have the same structure except the front plug insert of test terminal and the tip of test plug. Four-pole and two-pole types are available. They can be applied to 3-phase 3-wire circuit, 3-phase 4-wire circuit, zero-phase circuit and single phase circuit.

MAGSIGN is not luminous type indicators like lamps or LED's.
MAGSIGN operates by magnetic-inversion-type indicators which invert permanent magnetic disks (indiction plates) by electrical pulse signals.
