  Phase Rotation and Continuity

PHASE ROTATION & CONTINUITY PC15250  £73.50


• Quickly and simply prove continuity of all 3 lines
• Identifies which are faulty and shows the sequence of phase rotation.

• Fast & effective method of identifying worn or unmarked cables, and ensuring 3-phase outlets and machinery are wired correctly.

• Retractable GS38 probe shields give a choice between long exposed tips for reaching inaccessible contacts and safer, shorter lengths for normal working.

• Fully compliant with GS38 and BS EN 61010.
• Proves continuity
• Identifies faulty lines
• Shows direction of phase rotation

phase sequence indicator
PHASE SEQUENCE INDICATOR PSI3000 PSI3300 - £119.00

The Martindale PSI3000 is the ultimate phase sequence (rotation) indicator. It combines an easy to follow rotating disc with fault indicators showing if any of the phases are down. The disc continues to rotate after disconnection, giving more time to identify the phase sequence.
