Manual Transfer Switch
The manual transfer switch allows the user to start up a standby generator and restore power to pre-designated, critical circuits when the primary generator or utility power is not available. Our transfer switch, available in 3 or 4 pole (neutral switching) offers three stable positions which ensures isolation of the two asynchronous power supplies, eliminating any risk of short circuits. The transfer switch enclosure is encased is a tough, rugged roll cage to protect external components and accidental collisions with personnel or equipment. Designed to meet environmental and dynamic requirements of MIL-STD-810G.

UEC manual transfer switches can be configured to meet most requirements.

Available from 16 to 2500 Amps
Voltages up to 600 VAC, 50/60 Hz
