ABB TMAX T5N 630A 3-Pole Circuit Breaker PR222DS LSIG

ABB TMAX T5N 3-Pole 630A Moulded Case Circuit Breaker (PR222DS/P-LSIG)

The ABB TMAX T5N 630 is 3 pole Moulded Case Circuit Breaker (MCCB) that provides the greatest protection and dependability for demanding industrial power distribution systems and maritime electrical facilities. This 630 Amps unit comes with a very advanced PR222DS/P-LSIG solid state electronic release and has been designed by ABB as part of the world-famous SACE Tmax T series.

Unlike typical thermal-magnetic trip units, the integrated microprocessor based PR222DS trip unit offers completely customizable parameters for selective protection against overloads (L), short-circuits with delayed trip (S), instantaneous short-circuits (I) and ground faults (G). As such, it becomes an appropriate option in critical areas where power continuity, discrimination, and preventative machinery protection are of the utmost importance.

Installation and Maintenance Tips:

1. Check trip coordinates against dial settings: When placing this unit into a selective coordination arrangement, closely match the LSIG dip switch or display settings to your individual system coordination study. Setting the delayed short circuit ($S$) or instantaneous ($I$) thresholds incorrectly can cause premature tripping of upstream breakers.
2. Be Aware of Torque Values Always use a calibrated torque wrench while tightening front terminal bar connectors. Loose connections on a 630A circuit can cause thermal hotspots, which damage the MCCB housing and cause false thermal overload trips.
3. Megger (Insulation Resistance) CAUTION: To safeguard internal microprocessor circuits from static damage, disconnect or isolate the electronic PR222DS trip unit plug-in accessories during high voltage insulation resistance tests of your switchboard busbars.
