EMOS VT‑310 Voltage Tester (Model M0014A / 2201012000)

The EMOS VT‑310 is a two‑pole voltage tester designed for both AC and DC circuits between 110 V and 400 V. It enables identification of the phase conductor, checks phase sequence in three‑phase systems (with neutral), and determines polarity in DC systems. It is suitable for installation and maintenance work in wiring systems belonging to over‑voltage category CAT III 400 V. :contentReference[oaicite:1]{index=1}

Key Features

Why Choose the VT‑310?

• Excellent tool for installation and maintenance work on 110‑400 V AC/DC circuits with the ability to detect phase, sequence and polarity.
• Simple, reliable design with optical indicators and powered by the circuit under test—no battery changes required.
• Complies with CAT III 400 V safety standard and IP54 protection making it suitable for installation environments. :contentReference[oaicite:12]{index=12}

Usage & Considerations

• Only indicates presence of voltage and polarity/phase sequence; it is **not** a full multimeter for measuring exact values of voltage, current or resistance.
• Ensure you follow safe working practices: use appropriate personal protection equipment, verify test leads/connectors are in good condition, and understand that this is a tester/detector rather than a precision measuring instrument.
