Model Industrial Transfer Switches

The Power Series Transfer Switch line features 3 different platforms with multiple technologies to offer the most flexible solutions up to 5,000 AMPs. All platforms are rated for 3 cycle operation with highly reliable mechanisms with safety interlocks. Service entrance models are 100 percent rated and available with integral overcurrent protection. These distinctive Generac models combine an automatic transfer switch with an isolation mechanism and a manual bypass switch to provide redundant power transfer and re-transfer capability for critical-need applications requiring consistent and uninterrupted power to the load.

Features

Features Double-throw, solenoid-operated transfer mechanism | Isolated Compartments for improved safety | Entry is top and/or bottom | Single motion rack-out with doors closed | Dual ATS capability – Bypass contactor can be controlled by the ATS controller in the bypass mode of operation. The design allows the switch controller to remain active in both the ATS and Bypass modes, thus providing control to either contactor. This ability of the controller to remain active to control the Bypass isolation contactor provides “N+1” redundancy of a second fully functioning ATS. | Field-selectable multi-tap transformer panel permits operation on a wide range of system voltages | Mimic diagram with Source Available and Connected LED indication | 4.3 inch Color Display | Event logging and recording 450 time-stamped events | System TEST pushbutton | Programmable plant exerciser | Modbus® RTU | 3-Phase under and over voltage sensing on normal and emergency sources, plus load | Under and over frequency sensing on normal, emergency and load | 3-Phase sequence sensing for phase sensitive loads | 3-Phase voltage unbalance and loss sensing | Source available: Source-1 Present, 2-N.O. & 2 N.C. / Source-2 Present, 2-N.O. & 2 N.C. | Switch position: Source-1 Position, 1-N.O. & 1-N.C. / Source-2 Position, 1-N.O. & 1 N.C. | Pre Transfer Contacts: 1-N.O. & 1 N.C. |
