Product information

Description

The UNI-T UT07B-EU power outlet tester is an expanded version of the UT07A-EU model that combines standard socket wiring diagnostics with a built-in residual current device (RCD) test. The device identifies common wiring faults and additionally verifies the operation of RCD protection, providing a quick way to assess both wiring correctness and electric shock protection effectiveness.

Advantages

The built-in RCD test function generates a leakage current of approximately 30 mA to check whether the residual current circuit breaker operates correctly. Clear LED indications allow immediate identification of problems such as missing neutral or protective conductors, swapped phase and neutral wires, or incorrect grounding. The tester is designed for standard European mains (230 V, 50–60 Hz) and is compact and lightweight for easy use in homes, offices, and workshops.

Key specifications

  • Manufacturer: UNI-T
  • Model: UT07B-EU
  • Operating voltage: 230 V
  • Operating current: <18 mA
  • Frequency: 50 Hz ~ 60 Hz
  • RCD test current: ~30 mA
  • Indicator of correct connection: Yes
  • No grounding indicator: Yes
  • Indicator of no neutral wire: Yes
  • Weight: 80.5 g
  • Dimensions: 65 x 65 x 61 mm

How to use

Insert the UNI-T UT07B-EU tester into the mains socket to be checked. Observe the LED pattern to determine wiring status and whether grounding and neutral are present. To test RCD operation, press the built-in RCD test control to create a leakage current of about 30 mA and verify that the residual current device trips as expected. Remove the tester after completing checks.

Recommendations

Use the tester only on sockets with the same nominal voltage and frequency (230 V, 50–60 Hz). If the device indicates faults or the RCD does not trip during the test, consult a qualified electrician before using the circuit.
