Description

Megger PSI410 Phase Sequence Indicator

Product Details:

The new Megger PSI410 phase rotation indicator is a self powered unit that provides rapid indication of correct phase sequence using three dual-coloured LEDs and a specific audible tone. Clockwise rotation is indicated by green LEDs that light in a clockwise sequence with a continuous tone. Anti-clockwise rotation is shown by red LEDs lighting in a counter clockwise sequence and a warbling tone. The LED display of the PSI phase tester also indicates if all three phase are present, a green LED indicates a present phase, a red LED shows a missing phase connection. The dual phase colour coding means that the unit is simple to use on both brown/black/grey and red/yellow/blue colour coded supplies. The PSI410 has been designed to provide a slow rotational lighting speed to allow for easy identification and prevent the display rotating at the supply frequency.

The Megger PSI 410 phase sequence indicator has a tough, rugged case suitable for an industrial environment and comes supplied with long fused test leads with croc-clips and prods. The prods have insulated tips exposing less than 4mm of the tip. The PSI410 is an ideal addition to an electrician’s tool kit and provides a quick and simple means of checking phase sequence on motor, pump and air conditioning three phase supplies. Correct sequence of the phases is vital with many motors and pumps as damage to brakes and valves will occur in minutes with incorrect phasing.

  • LED clockwise and anticlockwise phase rotation indication

⏱ Dispatch & Delivery Timing

We aim to dispatch all in-stock orders promptly, but delivery depends on both when you order and which service you select.

  • UK orders: placed by 2:00 PM Monday–Friday are usually dispatched the same day.
  • International orders: placed by 2:00 PM Monday–Thursday are usually dispatched the same day.

Orders placed after these times are processed the next working day. This means delivery may occur the following day or later, depending on the courier and service selected.

Once dispatched, your chosen delivery service determines how quickly your parcel arrives:

  • Standard services We use Royal Mail Tracked 24 or DHL Parcel as our ‘Standard’ services. They are not guaranteed to arrive next working day.
  • Premium services (e.g. Royal Mail Special Delivery or DHL by Noon) offer guaranteed delivery windows.

If your order is time-sensitive, we strongly recommend choosing a guaranteed service or contacting us before ordering to confirm availability.

Please note: For logistical reasons, we may occasionally adjust the delivery method selected at checkout. For example, smaller items may be better suited to letterbox-friendly packaging or may be at greater risk of delay or loss via certain services. We actively monitor courier and postal service disruptions—including strikes and delays—and may modify shipping arrangements to help ensure timely and secure delivery.


📅 Busy Periods & Delays

We always aim to dispatch promptly, but delivery times may be affected by:

  • Seasonal demand (e.g. Christmas, bank holidays, or industry shutdowns)
  • Courier network delays outside our control
  • Supplier lead times or calibration requirements for certain equipment

If your delivery is time-critical, please contact us before ordering so we can confirm stock and courier availability.
