      What distribution board is required for the CH25843 chassis?

      For the customized distribution board for 72 pole (18 mm) and 12 pole (27 mm) chassis, you need to submit request for a quote to "au.estimating@schneider-electric.com". Our Standard distribution board only goes up to 60 pole (18 mm) and 12 pole (27 mm).

      What is the function of an SDX switch?

      What is the function of the SDX relay module for Powerpact H J and L circuit breakers?

      Product Line:
      Circuit Breakers

      Powerpact H, J, and L circuit breakers with advanced Micrologic trip units

      Circuit breakers equipped with Micrologic 3, 5, and 6 trip units can take the optional SDx Module.
      The SDx Module receives data from the trip unit through a fiber optic link.

      Default alarms are as follows
      • Micrologic 5 trip unit:
      — Output 1 is the thermal fault indication (SDT).
      — Output 2 is the long-time pre-alarm (PAL Ir).
      • Micrologic 6 trip unit:
      — Output 1 is the thermal fault indication (SDT) for electrical distribution applications.
      — Output 1 is None for motor-feeder applications.
      — Output 2 is the ground-fault indication (SDG).
      • For Micrologic 3 trip units, the SDx is nonconfigurable and indicates thermal trip alarm

      • For Micrologic 5 and 6, SDx can be configured for different alarms.
      Note that the SDX can be used for ground fault alarm on non configurable 6 (LSIG) trip units, but it will not provide ground fault alarm on a Micrologic 5 (LSI) trip unit.  Therfore, GF alarm without tripping is not possible.
      All alarms on a trip, failure, and maintenance event and all alarms associated with a measurement previously activated in the Alarms tab can be assigned to an SDx Module output.
       For complete list, refer to Alarms section of  manual 48940-312-01.
      To set alarms, access the SDx Module output settings using the RSU software under the Output tab.
