Ludkounty, izennitting RA series Transfer Switches RA12 Transfer switch mechanism ................................................................ ................................................................. ................................................................ ........................... . . Specifications le A powerful and economical solenoid powers RA. Transfer Switches. ■ Independent break -before -make action is common for 2-pole. * Mechanical interlock prevents simultaneous closing of normal and emergency contacts. ® Electrical interlocks prevent simultaneous closing signals to normal and emergency contacts and interconnection of normal and emergency sources through the control wiring. ® Long -life, high pressure, silver alloy contacts resist burning and pitting. Contacts are mechanically held in both normal and emergency positions for reliable, quiet operation. Voltage rating Transfer switches up to 240 VAC 50 Hz or 60 Hz. Amperage rating Transfer switches rated for 100, 200 and 400 A continuous amperes. Arc interruption Multiple leaf arc chutes cool and quench the arcs. Barriers prevent interphase flashover. Neutral bar A full current -rated neutral bar is standard on enclosed 2-pole transfer switches. Auxlllary contacts Two contacts rated at 5A continuous at 100 VAC or 2.5A continuous at 200 VAC (one for each source) are provided for customer use. Wired to terminal block for easy access. Storage temperature -25" C -13" F to 55" C 131" Humldity Up to 90% @ 20'C Altitude Up to 2,000 m 6,561 ft without deratin Total transfer time (source -to -source) Will not exceed 100 msecs with normal voltage applied to the actuator. Manual operation handles Transfer switches are equipped with a removable operating handle which allows operation during servicing in order to facilitate troubleshooting with sources of power disconnected NAS-5810a-EN-S (10115) I RA13 UL 1008 withstand and closing ratings Transfer switch . ampere Coordinated molded case breakers 100A 22,000 200A 22,000 100A SE 10,000 200A SE 10,000 400A 35,000 400A SE 35,000 I I i 1 Enclosures Wire bend space complies with 2013 NEC.
