Allen-Bradley TCS2P125-22M Automatic Transfer Switch

The TCS2P125-22M Automatic Transfer Switch from MTS / Kutai Electronics is a 2-pole, 125 A unit rated for 220 VAC single-phase operation (180–270 VAC range), designed to automatically transfer loads between utility power and a standby generator during outages or abnormal voltage conditions. It is electrically operated with mechanically held contacts and supports both automatic and manual transfer, guided by a TC-V2 digital controller that provides over-voltage and under-voltage protection, adjustable transfer delays from 0 to 99 seconds, and a generator exercise timer adjustable from 1 to 4 weeks with or without load. This switch is commonly used in residential backup power, telecom sites, and other generator systems requiring uninterrupted power, and features UL94V-0 flame-retardant plastic components, a rated short-time current of 3 kA for 1 second at 250 VAC, a short-circuit peak current of 7.5 kA, 50/60 Hz operation, a contact life of over 6,000 operations under load, and an approximate weight of 4 lb (1.8 kg); mounting options include switch-mounted or door-mounted controllers.
