Fluke Mains Socket Tester, 230V Voltage, 300V Safety Category Voltage - ST240+/UK


This mains socket tester provides quick verification of 3-pin, 230V outlets and RCD-equipped sockets in commercial and industrial environments. It offers Visual LED indication and an optional audible signal to help identify common wiring faults and confirm the presence of hazardous voltage, enabling Rapid circuit identification and Basic safety checks on site.

Features & Benefits


• Detects six wiring conditions for fast fault identification
• Integrated switchable beeper aids circuit breaker tracing
• Performs single-button RCD test to verify trip operation
• Operates at 230Vac with 4mA test current for earth leakage detection
• Three LED indicators deliver clear Visual status at a glance
• Rated to 300V CAT II for use within defined safety category limits

Applications


• Suitable for electricians checking domestic and commercial outlets
• Ideal for verifying RCD function in healthcare and office installations
• Used for locating corresponding circuit breakers during maintenance
• Can be used for routine site safety inspections of 3-pin power outlets
• Used with portable tool kits for field fault diagnosis and verification

How does the audible function support fault finding?


The switchable beeper emits a tone whenever voltage is present, enabling you to trace the correct breaker at the distribution panel by listening for the tone to change as breakers are operated.

What wiring errors can be identified visually?


The three LEDs map to a quick-reference chart that distinguishes correct wiring, earth fault, NEUTRAL fault, live fault, live/NEUTRAL reversal and live/earth reversal.

What electrical rating should I expect when carrying out tests?


The tester is intended for 230Vac supply and uses a 4mA test current when performing earth leakage-related checks.

Are there options for carrying or protecting the instrument?


Accessories listed for use with the device include protective EVA hard cases and a tool organiser bag suitable for secure transport.
