Section 8—Accessories for Micrologic™ Trip Units
NSX Cord
Micrologic trip units are connected to the Modbus communication interface module (IFM) or front
display module through the internal terminal block for the NSX cord equipped with an RJ45 connector.
The NSX cord is available in two cable lengths:
•
4.27 ft. (1.3 m)
•
9.84 ft. (3 m)
Lengths up to 32.8 ft. (10 m) are possible using extensions.
•
For voltage V 480 V, available in 3 prefabricated lengths: 0.35 m, 1.3 m and 3 m.
•
For voltages V > 480 V, a special 1.3 m cable with an insulation accessory is required.
•
A set of cables with RJ45 connectors is available to adapt to different distances between devices.
Breaker Status and Control Module (BSCM)
Functions
The optional BSCM Breaker Status & Control Module is used to acquire device status indications and
control the communicating remote-control function. It includes a memory used to manage the
maintenance indicators.
Status indications
Indication of device status:
Auxiliary switch (OF), alarm switch (SD), and overcurrent trip switch (SDE).
Maintenance indicators
The BSCM manages the following indicators:
•
mechanical operation counter
•
electrical operation counter
•
history of status indications.
It is possible to assign an alarm to the operation counters.
Controls
The BSCM can be used to carry out communicating remote control operations using the
communicating motor operator (open, close and reset) in different modes (manual, auto).
Mounting
The BSCM can be installed on all PowerPact H-, J-, and L-frame circuit breakers and automatic
switches with Micrologic trip units. It simply clips into the auxiliary contact slots. It occupies the slots of
one auxiliary switch (OF) and one overcurrent trip switch (SDE). The BSCM is supplied with 24 Vdc
power automatically through the NSX cord when the communication network is installed.
