Protection & Control for Low Voltage – Industry, Water, Oil & Gas

Motors and Generators Protection Control Relays

Fanox designs and manufactures the most reliable protection & control relays in the market. Products that efficiently prevent engine burnouts, saving costly repairs and preventing dreaded and unnecessary downtime in any important process.

Experience shows that motor protection is still a novelty, and still not a priority amongst users. The high numbers of faults that occur every day are mainly due to overloads, locked rotor, phase failure or imbalance, heavy bursts of long duration or high duty cycle of operations, or overheating.

Over 60% of failures are due to causes not detected by conventional protection systems, causing excessive heat in the windings, leading to a drastic reduction of the electrical life of the motor.

The most significant technical advantages of Fanox designed equipment is:

  • Continuous Thermal image memory of heating and cooling cycles of the engine’s starting cycles, work overload and stoppages.
  • The prompt detection of phase loss, even with the engine running at low loads, stopping quickly to avoid costly breakdowns.
  • Identification of trip cause. The relays indicate the reason for tripping instantly allowing you to identify and act quickly on faults.

Pump Protection & Control Relays

“HOW TO GET THE MAXIMUM PROTECTION FOR SUBMERSIBLE PUMPS WITHOUT LEVEL SENSORS AND WITH THE MINIMUM COST”

Fanox, one of the main specialists in the world on electronic protection engines, have designed a complete range of electronic relays for submersible and surface mounted pumps protection, that covers almost all the needs of the pumps without changing brand.

Fanox relays are much more reliable and affordable than the relays that are used with level sensors and are the only ones in the market that control the three phases of the motor supply, protecting from empty pump, cavitation, etc. Indeed, they are also the only ones on the market with thermal image, this is very important, because they control with accuracy the heating and cooling of the pump during all cycles, starting, working and stopping cycles. This feature makes almost impossible to burn up a pump.

“We have the authority to say this because we have tested and verified that the rest of the devices in the market only protect one phase, which in some cases can bring out serious problems. We have a complete and specific study on The advantages of electronic protection versus protection with level sensors available for all those customers who request it.”

The leading companies in this sector now use these relays with a high level of satisfaction, due to the good results that they are getting.

Pump Protection & Control Panels

Why protect your pumps and panels with electronic relays from Fanox?

  1. To avoid dry running of the pump without the use of level sensors.
  2. To avoid nuisance tripping. Motors are shut down in case of fault and automatically reconnected without having to go on-site to reset.
  3. The relays have Thermal image memory which allows total control of heating and cooling cycles  of the pump during start-up, operation and stopping,
  4. They offer added protection such as Phase Failure, Phase loss and Phase Inversion.
  5. Easy and quick installation. Maintenance free, and adaptable to already existing installations without downtime and removal of pump from its place.
  6. Cost savings.

CBM – Single Phase Panels

One of the most critical situations in pump operation is dry running. The solution offered by FANOX single-phase protection panels is based on measuring the undercurrent. In dry running situations a current decrease is detected. This reduction of consumed current is measured by the PS-R electronic relay fitted to the protection panel: when the preset undercurrent value is reached, it switches the pump off.

CBT – Three Phase Panels

The cosine of phi (Cos φ) is the value of the cosine of the phase angle between the voltage and the intensity of the electrical current. This oscillates from a value slightly below 1 for a full load operating motor to almost 0 when it is dry running.

Therefore, in dry running situations, cos φ falls significantly. This reduction is monitored by the PF-R relay installed in FANOX three-phase protection panels, meaning that when it falls beneath the adjusted value, the panel shuts down the pump and protects it from damage.

CBS – Three Phase Panels with Soft Starter

Fanox protection panels with progressive startup and shut-down are fitted with ES soft starters to prevent problems caused by water hammering or sudden start-ups and shut-downs.

Protection against dry running is provided by the PF-R relay that monitors the value of cos φ and shuts down the pump when it falls below the selected value.

Earth Leakage Protection Relays

Transient Overvoltage Protection (TVSS, SPD)

Renewable Energy

The surge protection relays protect installations and eliminate the effects of power surges. They offer the highest level of security in low voltage lines, continuous processes, domestic and tertiary facilities, etc.

The most visible and destructive power surges are often caused by atmospheric discharges (lightning strikes). However, this is not the most common source of such disturbances, as in most cases, the main sources of surges are within the facility installation itself, amongst others for the following reasons:

  • Performance of circuit breakers and fuses.
  • Connection and disconnection of inductive loads.
  • Switching of motorsand machines.
