Trip relays possess a standard hand-reset flag and operate within 10 ms. Table 1 shows the trip relay versions availableSelf-reset relays reset when the initiating signal is removed, making them suitable for use as trip relays in auto-reclose schemes and also for general flagging purposes. Hand-reset relays require manual resetting, making them effective lockout relays which are commonly used to trip circuit-breakers associated with transformers. Electrical-reset relays require a voltage to be applied to the unit to reset the contacts. These relays may be used in auto-reclose schemes, or where remote resetting of the relay is required.When the break contact cuts off, the high burden is held until the time delay circuit switches it out. This time delay allows any flagging or auxiliary element in series with the tripping relay to operate before full cut off. The relay is reset by means of a pushbutton located on the front cover. For type MVAJ 20 relays, each element is reset separately.
