Air break starters
for high voltage motors
Sa! This new air break c o n t a c t o r — a r o u n d which Allen-Bradley has developed a complete line of high voltage starters — is designed t o m a t c h your ΙουμΙιβίΙ applications. It features the same solenoid design — with only one moving part — that has made Allen-Bradley low voltage starters universally recognized for their tremendous operating life. These new contactors are available in full voltage and reduced voltage starters — nonreversing or reversing—for squirrel cage, part winding, slip ring, and synchronous motors u p to 1500 h p . 2300 volts: 2500 h p , 4600 volts. All starters are equipped with current limiting fuses and have an interrupting capacity of 150.000 kva at 2300 volts and 250.000 kva at 1600 volts.
