Section 9—Accessories and Auxiliaries
All PowerPact™ H-, J-, and L-frame circuit breakers and automatic switches have slots for the
electrical auxiliaries .
Circuit breakers equipped with Micrologic™ trip units may be equipped with a fault-trip indication to
identify the type of fault by installing
• one indication module with two outputs (see page 119)
— either an SDx module with Micrologic 3.x / 5.x A or E / 6.x A or E
— or an SDTAM module with Micrologic 2.x M.
This module occupies the slots of one auxiliary switch (OF) contact and an undervoltage trip
(MN)/shunt trip (MX).
All these auxiliaries may be installed with a motor operator.
Communication Network
Communication networks require specific auxiliaries.
Communication of status indications:
• 1 BSCM module
• 1 NSX cord (internal terminal block) for both communication and 24 Vdc supply to the BSCM.
Communication of status conditions is compatible with a standard motor operator.
Communication of status indications and controls requires, in addition to the previous auxiliaries:
• 1 communicating motor operator connected to the BSCM.
Communication of measurements is available on Micrologic 5/6. The system consists of:
• 1 NSX cord (internal terminal block) for both communication and 24 Vdc supply to the Micrologic.
Communication of measurements is compatible with a standard or communicating motor operator.
Communication of status indications, controls and measurements is available on Micrologic 5/6. The
system consists of:
• 1 BSCM module
• 1 NSX cord (internal terminal block) for both communication and 24 Vdc supply to the BSCM and
the Micrologic
• 1 communicating motor operator connected to the BSCM.
Installation of SDx or SDTAM is compatible with communication network.
