Penncat Corporation Automatic Transfer Switches Series TS 840

Thomson Technology TS 840 series of Automatic Transfer Switches employ two mechanically interlocked enclosed contact power switching units and a microprocessor based controller to automatically transfer system load to a generator supply in the event of a utility supply failure. System load is automatically re-transferred back to the utility supply following restoration of the utility power source to within normal operating limits. TS 840 Automatic Transfer Switches are certified for use in emergency power system applications for light industrial, telecom and agricultural markets that require automatic standby power. The standard TS 840 Automatic Transfer Switch is rated for 100% system load and requires upstream overcurrent protection. All TS 840 series automatic transfer switch models have been 3 cycle short circuit withstand current tested in accordance with UL 1008 & CSA 22.2 No. 178. All TS 840 automatic transfer switches are supplied with NEMA 3R outdoor weatherproof enclosures as standard.
