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 ...
