BENNING SDT 1
Socket tester with contact sensor for active PE error detection, and for testing the tripping function of a 30 mA RCD
Application
Quick and easy testing of shock-proof sockets, cable reels, and extension cables for proper connection. Wiring errors and high contact voltages at the PE connection are indicated directly. In addition, it is possible to test the tripping function of a 30 mA RCD by pressing the FI/RCD TEST key.
Testing Functions
- Indication of correct wiring via LEDs.
- Wiring errors such as missing PE, N, and L conductors, as well as an inversion of the L and PE conductors are clearly indicated via three LEDs.
- An active PE test by means of a contact electrode and the LCD provides a warning of a dangerous contact voltage (> 50 V) being applied to the PE connection.
- FI/RCD TEST key for testing the tripping function of 30 mA RCDs.
Features
- Safe and easy operation by trained personnel
- Status table provides information about the correct connection (OK, green), and the type of existing errors (red) at the shock-proof socket.
