Safely determine 3-phase sequence and rotation direction without exposed metal contacts using the Major Tech Non-Contact Safety Phase Indicator (MT936). Designed for industrial electricians, plant engineers, and maintenance technicians, this instrument utilizes insulated clip-on sensors to measure voltage fields directly through wire insulation. Featuring bright LED direction indicators, adjustable display brightness, and magnetic mounting capabilities, it offers maximum safety during phase verification on live distribution systems.
Key Features:
-
Non-Contact Insulated Testing: Measures 3-phase sequence over insulated conductors up to $10\text{ M}\Omega/1000\text{V}$, eliminating direct metallic contact with live wires.
-
Phase Sequence & Rotation LEDs: Clear visual LED indicators display active phases (L1/L2/L3) and clockwise or counter-clockwise phase rotation direction.
-
Broad Cable & Voltage Range: Accommodates conductor sizes from $\varnothing2.4\text{ mm}$ to $30\text{ mm}$ across a 3-phase voltage range of $70\text{V}$ to $1000\text{V AC}$ (continuous sine wave to earth).
-
Adjustable Display Brightness: Integrated Brightness Button enhances LED indicator visibility when working in dimly lit panels and electrical rooms.
-
Hands-Free Magnetic Mounting: Built-in rear magnet allows the unit to attach directly to metal distribution boards and enclosures.
-
Smart Power & Battery Protection: Features a low-battery warning (Power LED flashes at $7.2\text{V} \pm 0.2\text{V}$) and automatic power-off at $6.2\text{V} \pm 0.2\text{V}$ or lower.
Detailed Description:
The Major Tech MT936 simplifies phase rotation checks while prioritizing operator safety. By utilizing inductive crocodile clips, technicians can perform quick phase sequence tests on insulated supply cables without stripping wire insulation or coming into contact with live terminals.
Designed to meet CAT IV 600V and CAT III 1000V safety standards, the MT936 provides reliable rotation identification for motor wiring, generator synchronizing, and distribution panel installations.
