Handheld phase sequence tester with three insulated clamp jaws and magnetic back

ETCR

ETCR1000D Non-Contact Phase Sequence Tester, AC 70-1000V, Wire 10-40mm

SKU CH-MPSM-5SHAS

Detects phase sequence on live AC lines from 70 to 1000V using insulated clamps that fit wires 10 to 40mm wide

  • Non-contact testing keeps hands clear of live conductors
  • Wide AC 70-1000V range covers most industrial supplies
  • LEDs and buzzer show rotation and missing phase instantly
  • CAT 1000V rating with 6000V overvoltage protection meets EN61010
  • Magnetic base and insulated clamps enable hands-free operation

Non-Contact Phase Sequence Tester

The ETCR1000D is a non-contact phase sequence tester designed for electricians and maintenance technicians. It detects phase rotation on insulated conductors without stripping insulation. The instrument operates on AC voltages from 70 to 1000V at 45 to 65Hz. Clamps accommodate wire diameters from 10mm to 40mm for versatile use.

Suited for live line checks and routine maintenance

This tool suits professionals who need quick phase orientation, live status, and breakpoint detection on energised circuits. Magnetic backing allows hands-free mounting on distribution boxes up to 800g. Buyers who require contact probes or measurements on cables thinner than 10mm should consider other instruments.

Stable indication during continuous operation

LEDs show clockwise or counter-clockwise rotation and missing phase status while a buzzer provides audible alerts. The meter draws power from two AA alkaline batteries and auto-shuts down after five minutes. It meets EN61010-1 and EN61010-031 standards with CAT 1000V rating and 6000V overvoltage withstand for sustained safety.

Questions about this item

What battery type does the ETCR1000D need before I can start testing?

Two AA alkaline LR6 cells power the unit; the POWER lamp lights at start-up and the LOW BATTERY lamp warns when they need changing.

Will the clamps fit the 10 mm and 40 mm insulated conductors I already have on site?

Yes, the jaws accept external diameters from 10 mm to 40 mm, covering both sizes you mentioned.

How do I confirm the tester is showing the correct phase rotation after clamping on?

The LEDs indicate clockwise or counter-clockwise sequence and live status, while the buzzer sounds for positive, negative or missing phase.
