3 Phase - Phase Changer Over with Timer
A 3-phase motor starter with automatic phase changeover, dry-run, overload, and single-phase failure protection, along with a digital meter and timer.
₹4299.00
During power outages, the phase sequence on your incoming 3-phase supply can shift when power comes back — which normally means manually rewiring the connections to keep your motor running correctly. This starter handles that on its own. Using two relays, it automatically detects the change and switches over within a few seconds — no manual rewiring needed, no waiting around after every outage.
On top of that, it protects your motor from the most common causes of damage: running dry, drawing too much current, and losing one of its three phases. Dry-run protection detects when your pump has no water to draw and shuts the motor off automatically, before it can damage itself running empty. A side switch lets you bypass dry-run detection if you're using this for a motor other than a water pump. Single-phase failure protection watches all three incoming phases and stops the motor if any one of them drops out. Overload protection is set automatically — the first time you install the panel, just hold the "Set" button for 2 seconds, and it detects and sets the right trip current for your motor on its own.
A digital timer lets you set a running duration — anywhere up to 5 hours, adjustable in minutes — and once that time is up, the motor switches off on its own; your last setting stays saved. A separate digital meter shows running current by default, with a button to check incoming voltage. Indicator lights for Motor On, Overload, Dry Run, and 3 Phase On keep you informed at a glance. Starting is a simple push-and-hold, and a dedicated Stop button gives you an instant, deliberate way to cut power.
Everything sits inside a solid, powder-coated metal body built for daily use.
