Type A Earth Leakage protection is essential for safety in electrical systems where both AC and DC currents are present. It safeguards against both sinusoidal and pulsating DC residual currents which are common in most modern electronic equipment. This protection prevents electric shocks, fires, and equipment damage caused by insulation ...

Alternating Relays can be used in various ways in applications that need to control and balance the wear between pumps, compressors and other rotating machines. The most basic of the relay family is the variant that simply requires one input to control the outputs which are connected to two loads. <...

Fundamentally, both timers are similar in that they provide a delay period that the relay remains energised for from an initial trigger. However, the trigger method for both is different. True Delay Off - This timer utilises storage capacitors internally which retain their charge when the power is ...

A phase loss fault is the condition caused by blown fuses, tripped circuit breakers, cable damage, open circuits, poor/loose connections and worn contacts. Allowing this fault to persist can lead to equipment failures and machine downtime. Read more

A phase reversal fault is a situation where two phases in a three phase system have been swapped. This typically occurs during equipment installation, upgrades or general maintenance. 3-phase motors and other rotating equipment rely on the order of the phases to be correct. That is, L1, L2 and L3 ...

Undervoltage is defined as a condition where the applied voltage drops to 90% of rated voltage, or less, for at least 1 minute. This condition if allowed to persist, can expose electrical devices to problems such as overheating, malfunction, premature failure and shut down, especially for motors (i.e. refrigerators, dryers and ...

Time delay relays are like normal relays however introduce a timing element in order to intentionally delay when the relay either turns on (energises) or turns off (de-energises). Used typically to control various types of equipment throughout many types of industries. Factory automation, production processes, lighting control, air conditioning, electrical ...

Overvoltage occurs when the supply voltage rises above the rated voltage of the motor or equipment and this can cause excessive current to flow as well as creating excessive voltage stresses. In both cases, the electrical insulation system inside the motor or equipment can be degraded reducing life and potentially ...
