• Type ms 61 c (lbs/bp) is a unique relay which recieves current input signals provided by sensors. Unique design ensures the relay settings that can be done directly in terms of primary current, thus avoiding complex ct ratio calculations. The value of fault current at the time of relay tripping is displayed in the backlit lcd display, till the relay is reset. The current and time settings are set using membrane keypads in a 2 line, 16-character backlit lcd display. This relay provides 6 types of standard idmt curves, a long time delay curve and also a definite time feature for both the o/c as well as the e/f relays. It is for use in circuit breaker feeder, a high set relay feature can be given for both o/c and e/f relays, which can be enabled or disabled. This entire relay settings are secured with password protection and is used for a load break switch feeder, then the relay offers only low-set idmt protection for both o/c and e/f relays. Leds are available for pick-up, low-set fault (o/c and e/f), high set fault (o/c and e/f), r/y/b phases and earth fault. Thus diagnosis becomes easier, during the relay pick-up as well as post trip conditions. The fully microprocessor based relay has two sets of output change over contacts each for the o/c and e/f relay. The over current settings are available from 5 to 200 a and earth fault settings from 1 to 80 a. Tms settings are available from 0.1 to 1.6. The high set o/c settings are from 20 to 2000 a and the high set e/f settings .
