In Pakistan, phase loss, reversed phases and voltage swings are common causes of burnt motors. A phase relay watches the incoming supply and drops out the motor contactor before damage is done. Fotek's PR-1 phase relay detects phase faults on the supply; the PVR-3 adds adjustable over- and under-voltage limits.
The FR-1 floatless level relay controls pumps and tanks with simple electrode probes instead of mechanical float switches — ideal for water tanks, sumps and process vessels. FR-1L suits long cable runs and FR-1H high-sensitivity applications with low-conductivity liquids.
These relays plug into standard 8- or 11-pin sockets and are ordered with the supply voltage. Send your motor or tank application and we recommend the relay.

| Part number | Description | Key spec | Quote |
|---|---|---|---|
| PR-1 | Phase relay for three-phase supplies, reset delay 2 s (add the supply voltage when ordering) | Phase failure | |
| PVR-3 | Phase and voltage relay: phase protection with over/under-voltage limits ±20% (add the supply voltage when ordering) | Phase + voltage | |
| FR-1 | Floatless level relay, standard type (ON < 30 kΩ, OFF > 60 kΩ) (add the supply voltage when ordering) | Standard | |
| FR-1L | Floatless level relay, long-distance type (ON < 4 kΩ, OFF > 15 kΩ) (add the supply voltage when ordering) | Long distance | |
| FR-1H | Floatless level relay, high-sensitivity type (ON < 70 kΩ, OFF > 300 kΩ) (add the supply voltage when ordering) | High sensitivity |

FAQs
If one phase is lost or the voltage drops, a motor overheats and can burn out. A phase relay stops the motor before damage occurs.
Electrode probes in the tank detect the liquid by conductivity, and the relay switches the pump at the high and low levels — no moving floats to stick.
