TELE Protects Your Pump

Learn how we help make your components last longer


Founded in 1963, TELE has been the market leader for manufacturing and developing customized solutions for the industrial control panel industry. Products we manufacture consist of time relays, monitoring relays, alternating relays, and liquid level relays. For over five decades, specializing in the pump, motor, water, and wastewater industries has shown us how important it is for us to make our products as efficient and reliable as possible. We guarantee that we can match or exceed our competitor’s product and performance.

“Breaking the bank or dealing with faulty products is not in our playbook.”




Measuring motor power is a clever way to gain load feedback about machine and process performance. Our load and power monitoring relays check on the electrical power consumption via the real power and power factor values. TELE’s G4BM480V12ADTL20 offers a display with two independent output relays and works in 1- and 3-ph networks.

Additionally, up to 480V AC and current of 12A can be connected directly while you always have the chance to connect an external current transducer (CT). This product is ideal to look at the entire power range (via real power) of a pump and can detect under, over, and nominal load conditions. Power is linear and a change in load is a change in power (horsepower or kilowatts).

Another way to zoom into an under-load condition (e.g. dry-running or a slipping v-belt) can be the power factor (cosine phi) monitoring. Our G2CM400V10AL20 can be a great way to protect your equipment, especially in critical under load conditions. For a lightly loaded motor, the power factor can be close to zero. Both products offer a Sensorless solution that easily connects to every pump, fan, v-belt system, or conventional drive and can trigger alarms or disconnect over/under performing installations via the integrated monitoring relays.

You can think of this low power factor as electrical inefficiency. The current is flowing to the motor, but it is not doing useful work (Power). As the load increases, the power factor improves and is typically close to 1 for a fully loaded motor.
