Overview

The ABB Installation Products SKU PAC79 is an Aluminum Type PAC Parallel Groove Clamp designed for reliable electrical connections in overhead and underground distribution systems. This clamp features a cast copper liner, engineered to accommodate a wide range of conductor sizes and types, ensuring optimal contact and conductivity. The main conductor range supported includes 336.4-1/0 AWG ASCR, 1/0-6 AR ASCR, 400-2/0 Stranded Aluminum, and 1/0-6 AWG Aluminum/Copper (AL/CU). For tap connections, it is compatible with ASCR conductors from 1/0 Stranded to 8 AWG Solid, as well as AL/CU conductors. Each clamp is prefilled with an oxide inhibitor, a critical feature for preventing corrosion and maintaining low resistance contact over the lifespan of the connection, particularly when joining dissimilar metals like aluminum and copper. The pressure-cast aluminum body effectively seals out moisture and resists corrosion, while the copper liner separates conductors to reduce the possibility of galvanic corrosion. The clamp includes a galvanized steel carriage bolt, nut, and lockwasher for secure assembly. The PAC79 is part of ABB’s corrosion-resistant groove clamp series, offering a robust solution for utility and industrial applications requiring secure and durable conductor terminations. Its high-strength, heat-treated cast aluminum alloy ensures long-term reliability in demanding power transmission and distribution networks. The clamp’s dimensions and bolt size are optimized for compatibility with standard conductor ranges, providing a dependable solution for both main and tap connections.

ModBus is a serial, asynchronous protocol. The ModBus protocol does not specify the physical interface. Typical physical interfaces are RS-232 and RS-485. The RMBA-01 provides a galvanically isolated RS-485 interface. ModBus is designed for integration with Modicon PLCs or other automation devices, and the services closely correspond to the PLC architecture. The RMBA-01 supports the RTU protocol only.

The FSO 12 safety functions module supports the following functions according to EN/IEC 61800-5-2:2007: Safe Torque Off (STO) (standard feature of the drive), Safe Brake Control (SBC), Safe Stop 1 (SS1), and, Safely-Limited Speed (SLS). Additional safety functions supported but not specified in EN/IEC 61800-5-2:2007: Safe Stop Emergency (SSE), Safe Maximum Speed (SMS), and, Prevention of Unexpected Start-up (POUS). The FSO 12 does not operate the drive, it only monitors the actions of the drive and commands safety functions to be executed. The request for safety functions can come from an external safety system, safety PLC or from an FSO 12 internal fault. The FSO module monitors that the drive operates within the configured limits, and if the limits are exceeded, activates the STO function in the drive within the response time. Activation of the drive STO function removes the torque and, if so configured, applies the brake. Commissioning and configuration of the safety functions requires Drive composer pro (DCPT-01-KIT). NOTE: The Safe Torque Off (STO) function does not disconnect the voltage of the main and auxiliary circuits from the drive. NOTE: This module does not support an encoder in safety applications.
