Black US-plug socket tester with LED display, 59.5 by 57 by 57 mm, flame-retardant ABS

AUTENS

AUTENS GFCI Outlet Tester 48-250V LED Display US Plug

SKU CH-9ZSE-5W47A

Checks US socket wiring and GFCI trip function while displaying live voltage from 48 V to 250 V on an LED screen

  • Detects wiring faults instantly with seven clear LED patterns
  • Built-in GFCI trip test verifies protection at >5 mA threshold
  • LED voltage display reads 48–250 V so a separate meter is unnecessary
  • Flame-retardant ABS housing meets CAT II 300 V safety standards
  • Compact 59.5 mm US plug fits standard outlets and works from 0–40 °C

Socket Tester for Electricians and Homeowners

The AUTENS GFCI outlet tester checks wiring correctness and trips RCD or GFCI protection on US plug sockets. A built-in LED display shows measured voltage from 48 to 250 volts across 45 to 65 Hz. Seven distinct light patterns identify faults such as open ground, open neutral or reversed polarity. The unit meets EN61010-1 and EN61326-1 standards with a CAT II 300V safety rating.

Fits Directly Into a US Wall Outlet

The tester plugs straight into a standard US receptacle without leads or adapters. Flame-retardant ABS housing measures 59.5 by 57 by 57 millimetres. Bright red LEDs remain readable in sunlight and a built-in light aids use in dark locations. Operating range covers 0 to 40 degrees Celsius at 20 to 75 percent relative humidity. No external power source or separate meter is required for basic socket diagnostics.

Replaces Separate Polarity Tester and Voltage Meter

Combining GFCI trip testing above 5 milliamps at 110 volts with RCD trip testing above 30 milliamps at 220 volts eliminates the need to carry two instruments. Voltage accuracy is stated as ±(2.0 %+2) across the full 48 to 250 volt range. The jump is worthwhile when a single tool must verify wiring faults, confirm protection device operation and display live voltage simultaneously. Not suited for buyers who need logging, data export or three-phase measurements.

Questions about this item

What voltage range does the tester measure and display on its LED screen?

The LED display shows voltage from 48 V to 250 V at 45-65 Hz with an accuracy of ±(2.0 %+2).

How much heat or noise does the unit produce when left plugged in all day?

It draws only milliamp test currents and has no fan or moving parts, so it generates negligible heat and runs silently.

What must the building already have for the GFCI and RCD trip tests to function?

A live US-style receptacle supplying 110 V ±20 V for the GFCI test (>5 mA) or 220 V ±20 V for the RCD test (>30 mA).
