About Megger MS400 Non-Contact Voltage Detector Medium and High Voltages

Megger MS400 is a non-contact voltage detector designed for reliable live/dead AC voltage verification in medium- and high-voltage electrical systems. It allows technicians to check for voltage presence without making direct electrical contact, helping improve safety during inspection and maintenance work.

Robust Design for Demanding Applications

With a rugged ABS plastic housing and IP54 water and dust resistance, the Megger MS400 is ideally suited for tough work environments such as substations and overhead power lines. Its compact, lightweight design and included carrying case ensure easy transport and handling during onsite inspections.

Safe, Fast, and Accurate Voltage Detection

Detect voltage reliably in less than one second with the MS400's non-contact technology. Visual LED and audible alarms provide clear, immediate indications, helping reduce risk during critical electrical maintenance and troubleshooting tasks.

FAQ's of Megger MS400 Non-Contact Voltage Detector Medium and High Voltages:

Q: How does the Megger MS400 indicate the presence of voltage?

A: The MS400 visually alerts users with an LED and sounds an audible alarm when AC voltage within the 1 kV to 40 kV range is detected, ensuring quick and unmistakable indication of live circuits.

Q: What types of environments can the MS400 be used in?

A: This detector is designed for operation in ambient temperatures between -10C to +50C and storage from -20C to +60C, with humidity up to 85% RH (non-condensing), making it suitable for both indoor and outdoor industrial settings, including substations and overhead lines.

Q: When should I use the Megger MS400?

A: Use the MS400 whenever safe, efficient, and immediate voltage detection is needed for routine inspections or maintenance in medium and high voltage electrical systems such as switchgears or substations.

Q: What is the process for operating the Megger MS400?

A: Power the device with two AA batteries, activate it, and bring the forked probe tip near the conductor or equipment. The presence of voltage is rapidly signaled via LED and sound in under a second. An auto power-off feature conserves battery life after use.

Q: Where can the MS400 be safely stored and transported?

A: Thanks to its durable ABS construction and protective carrying case, the MS400 can be safely stored or transported to various worksites, and it is resilient enough for atmospheric pressures and environmental changes encountered in fieldwork.

Q: What benefits does the MS400 offer compared to contact voltage detectors?

A: As a non-contact device, the MS400 enhances user safety by allowing voltage presence to be checked without direct contact, minimizing electrical arc risk or accidental shocks, especially in high-voltage environments.

Q: How does the MS400 meet safety and accuracy standards?

A: The MS400 complies with EN 61010-1 and CAT IV 40 kV safety standards, delivers 10% measurement accuracy, and ensures reliable function within its designated power and environmental limits.
