Compressor Motor Starting Equipment Features
Trane can provide compressor motor starting equipment built to rigid Trane specifications. The types of starters available include:
Low Voltage (200 to 600 volts)
•Star
•Full voltage
•Autotransformer, closed transition
•
Medium Voltage (2300 to 6000 Volts)
•Full voltage
•Primary reactor, closed transition
•Autotransformer, closed transition
Medium voltage starters are provided as standard with a
All starters provided by Trane include the following standard features for safe, efficient application and ease of installation:
•NEMA 1 starter enclosure.
•120 volt, 60 hertz, 1 phase fused pilot and safety circuits.
•Control power transformer (4.0 KVA) with 120 volt, 50 or 60 hertz, single- phase.
•One pilot relay to initiate start sequence from CenTraVac control circuit signal.
•Starter enclosures capable of being padlocked.
•Automatic transfer from wye to delta on any
In addition, Trane offers a wide selection of optional starter features.
•Starters with standard or high interrupting capacity circuit breakers, to provide disconnect means and short circuit protection (low voltage only).
•Ammeters and voltmeters.
•Special function pilot lights.
•Special NEMA enclosures.
•Ground fault protection.
•Power factor correction capacitors.
•I.Q. Data Plus monitor device.
If the CenTraVac compressor starting equipment is provided by others, the starter must be designed in accordance with the current Trane standard engineering specification
systems. However, the responsibility for providing proper starting and control systems must remain with the system designer and the installer.

Benefits
•Reduces starter installation costs 20 to
35 percent:
•By eliminating
•By eliminating
•By eliminating field installed disconnect switch (when optional circuit breaker is used)
•By eliminating starter mounting pad and required equipment room floor space
•By eliminating control wiring from starter to control panel
•Electrical system reliability is enhanced:
•By reducing the number of field electrical connections
•By making
•By testing the entire chiller/starter combination, in the factory
•By providing control components designed to operate with the unique CenTraVac motor/compressor start and protection subsystem
•Single Source Responsibility
Trane retains complete responsibility for the starter and associated chiller/ starter interconnecting wiring.
