Model ZTSMV Medium Voltage Transfer Switches The Standard of Quality in Design and Manufacturing

Introduction ZTS Series Automatic Transfer Switches have been the preferred standard for quality and reliability in the electrical industry. The ZTSMV Model medium voltage automatic transfer switches pro- vides that same quality for installations from 5kV to 15kV. The ZTSMV Model is designed for use in the most critical applica- tions: hospitals, military sites, airports, communications facilities, and computer installations. ZTSMV Model switches fit the need for dependable continuity of power where emergency or standby ap- plications exist. Backed by over 75 years of experience in manufacturing auto- matic transfer switches, as well as extensive experience in the de- sign and development of paralleling switchgear systems, the GE ZTSMV Model provides the reliable answer to critical medium volt- age switching applications. Like all GE switches, the ZTSMV Model is supported by a nationwide network of field service facilities. Construction The switching elements consist of two vacuum circuit breakers in- terlocked to ensure that only one set of contacts can be closed at any one time. The control module for transferring operations of the power unit is the same reliable microprocessor control system that GE has designed, built and used on our low voltage auto- matic transfer switches. The control module is physically isolated from the power portion by an insulating barrier. The completed unit is enclosed in a NEMA1 cabinet (NEMA 3R optional) and is both front and rear accessible. —State-of-the-art vacuum breaker design —Electrically interlocked for secure operation —Over-current protection for the load —A drawout P.T. trunnion design on utility to facilitate removal of control fuses from rear of cabinet —The control module completely isolated from power section —Standard indication of source availability —MX250 control with MSPES Options provided for use with generator as an alternate source —A control circuit disconnect switch —Capable of supporting modules to allow remote communication to annunciators, modems and SCADA systems —Drawout vacuum breaker design —Dual electrical interlocks —Compliance with ANSI/IEEE spec C37 and NEMA spec SG5 —A drawout P.T. trunnion design on utility and generator side to facilitate removal of control fuses while the system is operating —The control module completely isolated from power section —Standard indication of source availability —One year warranty Model ZTSMV Medium Voltage Transfer Switches Standard Features The ZTSMV Features:
