ASCO 300 Series Automatic Transfer...

Description

ASCO 300 Series Automatic Transfer Switch

The ASCO 300 Series ATS is perfect for applications where power interruptions are not an option. The 300 series switch has proven its dependability in critical industries such as telecom, agriculture, municipal and medical. The equipment is listed to UL standard 1008 to comply with safety and NEC installation requirements. The ASCO 300 Series switches are also the most compact designs for automatic power transfer switches in the industry. The following features set these switches apart.

Electrical Features

Standard Selectable Features

• Inphase monitor to transfer motor loads, without any intentional off time to prevent motor inrush currents from exceeding normal starting levels.
• Engine exerciser to automatically test backup generator each week. Includes control switch for testing with or without load.
• Selective load disconnect, double-throw contact to operate at an adjustable 0 to 20 second time delay prior to transfer and reset 0 to 20 seconds after
• 60 Hz or 50 Hz selector switch.
• Three-phase/single-phase selector switch.

Voltage & Frequency Sensing 

• Adjustable three-phase, close differential voltage sensing on normal source.
• Normal source pickup voltage is adjustable to 95% of nominal; drop-out is adjustable from 70 to 90% of nominal.
• Frequency sensing on emergency source. Pickup at 95% and dropout at 85% of nominal.

Time Delays:

• Adjustable time delay to override momentary normal source outages to delay all transfer switch and engine-starting signals.
• Transfer to emergency time delay. Adjustable from 0 to 5 minutes for controlled timing of load transfer to emergency.
• Retransfer to normal time delay. Adjustable to 30 minutes.
• Five-minute unloaded running time delay for emergency engine generator cool down.
• Four-second time delay to override momentary to ignore momentary voltage and frequency transients during initial genset loading.
