Fuse Direction Detection Device for Technicians – DMT-PS255

The Dumatec DMT-PS255 is an essential diagnostic tool for engineers and technicians to ensure the integrity of three-phase electrical systems. It provides high-accuracy detection of rotation direction and identifies open phases, protecting equipment from damage caused by incorrect wiring. Featuring long, flexible leads and a compact design built for harsh environments, its clear indicators make testing both fast and safe.

 Key Features

• Dual Monitoring: Simultaneously checks phase rotation sequence and identifies open phases in one unit.

• Wide Voltage Range: Operates effectively on systems from 200V up to 600V AC.

• Standardized Coding: Features color-coded leads (Red, White, Black) for precise (R, S, T) phase identification.

• Operational Reach: Equipped with 1.1m long cords for easy access to various testing points.

• Portable & Durable: Lightweight design (approx. 530g) with a compact build suitable for field use.
