Drummond MTL15 - CANS LTD

Drummond MTL15



The John Drummond MTL15 has a maximum working voltage of 1000V DC/AC rms and extended nominal voltage threshold indications of 50, 230, 400, 690C DC/AC rms. The CAT IV 1000V safety rating makes the MTL15 suitable for supply side applications in all installation categories as defined in BS EN 61010.

The robust design meets the recommendations of the Health and Safety Executive in their guidance notes on the electrician’s test lamp (GS38) as well as complying with the most recent changes to the voltage detector standard BS EN 61243-3 and the test equipment safety standard BS EN 61010.

Both the lamp housing and the probe have a finger shield and insulated probe tip with only 4mm of exposed metal. A two layer double insulated cable with white inner insulation gives a clear warning of abrasion that could compromise the user’s safety, and is resistant against heat and oil. The MTL Series of test lamps do not require batteries and have no ranges or switches to get wrong, ensuring reliable indication of hazardous voltages.

The MTL15 is supplied with six interchangeable test probes for safe and easy measurement in all types of application particularly where access is restricted. In addition to the standard 62mm straight and right angled probe, extended 130mm probes are included. For maximum ease of use, the right angled probes can be rotated through 90, 180 and 270 degrees and locked in position.

High intensity LEDs show four distinct bands of illumination for the different voltage thresholds up to 690V. The unique design provides a 360° viewing angle, even in bright sunlight. This allows reliable identification of potentially lethal voltages above 50V and enables the user to easily distinguish source voltages of different supply types.

The MTL15 test lamp is the ideal solution for safely proving dead in many high power applications including:

  • Wind turbines installations
  • Energy intensive process industries
  • High power variable speed drives
  • UPS systems
