Power-Operated Pad-Mounted Gear

S&C offers power-operated pad-mounted gear in Remote Supervisory and Source-Transfer PMH and PME Models. PMH models utilize directly accessible components, as shown on pages 38 and 39. PME models use elbow-connected components, as shown on pages 40 and 41. Both can be furnished with S&C’s unmatched choice of tap protection provided by S&C Power Fuses and Fault Fiter® Electronic Power Fuses; see pages 42 and 43.

All models reflect S&C’s uncompromising design and quality for ease of installation, operator convenience, and years of maintenance-free service.

Remote Supervisory PMH and PME Models

Remote supervisory models feature power-operated Mini¬Rupter® Switches which respond to opening and closing signals from a remote location. These models can be specified with a communication and control equipment group, for a completely integrated and self-powered automated switching and protection package.

The communication and control equipment group includes a battery and battery charger; voltage sensor for single-phase voltage sensing and control power; three-phase current sensing on power-operated switches; user-specified remote terminal unit or 5800 Series Automatic Switch Control, which supports the IntelliTEAM II® Automatic Restoration System; and communication device.

No external wiring or control power is required. Just connect the power cables, configure the RTU, and the gear is ready for service.

Source-Transfer PMH and PME Models

Source-transfer models use power-operated Mini-Rupter Switches to provide fully automatic three-pole switching of the sources serving critical loads, which require a high degree of service continuity. A field-programmable S&C Micro-AT® Source-Transfer Control continuously monitors the status of the two sources and, if voltage on the source serving the loads is lost, automatically initiates switching to transfer to the alternate source, thus restoring power to the loads.

Source-transfer models are totally self-contained switching and protection packages. Each is completely factory-assembled and ready for installation. No external wiring or control power is required.
