Megger PSI410 Phase Rotation Tester
Protect motors, pumps, compressors, and HVAC systems with the reliable Megger PSI410. Designed for electricians, contractors, and maintenance engineers, this professional phase rotation tester provides fast and accurate phase rotation checks on three-phase electrical systems.
Incorrect phase rotation can quickly damage motors, valves, and pumps. The Megger PSI410 helps prevent costly downtime by making it easy to verify the correct phase sequence before equipment is energised.
Fast and Reliable Three-Phase Testing
The Megger PSI410 is a rugged and easy-to-use phase sequence indicator built for commercial and industrial environments. With bright LED indication and clear audible alerts, this advanced phase rotation meter makes checking phase sequence simple and reliable.
Reduce installation errors, protect three-phase equipment, and complete every phase sequence test with confidence using the trusted Megger PSI410.
Why Choose the Megger PSI410?
This unit is designed to quickly identify clockwise and anti clockwise rotation on three-phase circuits. This professional phase rotation tester gives instant visual and audible confirmation, helping electricians safely commission motors, pumps and air conditioning systems.
Megger PSI410 Key Features:
- LED clockwise and anti clockwise indication
- Audible rotation alerts
- Triple LED phase presence indication
- CAT IV 600 V safety rating
- IP54 rugged housing
- Long fused test leads included
- Crocodile clips and prods supplied
- Dual phase colour identification
- Self-powered operation — no batteries required
The Megger PSI410 supports both Brown/Black/Grey and Red/Yellow/Blue phase colour systems, making it ideal for modern and older electrical systems.
Clear and Simple Phase Rotation Testing
The PSI410 is designed to make checking phase sequence quick and easy.
Easy-to-Read Rotation Display
- Green rotating LEDs with a continuous tone indicate clockwise rotation
- Red rotating LEDs with a warbling tone indicate anti clockwise rotation
The display rotates slowly by design, making the direction easy to see during a phase sequence test.
This makes this unit an ideal motor rotation tester for industrial electrical testing and commercial electrical installation work.
Accurate Phase Presence Detection
The PSI410 not only checks the correct sequence, but also confirms that all three phases are connected properly.
- Green LED = phase present
- Red LED = missing phase
This intelligent phase sequence indicator can also help identify a phase with lower voltage than the others, improving fault finding on three-phase electrical systems.
Built for Industrial Environments
The PSI410 has a tough IP54-rated case designed for demanding site conditions. Fused test leads and insulated probe tips help improve operator safety during electrical maintenance testing.
