Motor Protection
Historically, motor protection was provided in the starter by some type of monitoring system.
Starter manufacturers usually provide a full range of optional equipment mounted on the starter.
Eaton Cutler-Hammer
®
offers IQ metering and motor protection products for their starters.
Today,Trane provides most of the key motor protection and metering functions (see Table 2, first
column) within the chiller microprocessor control panel as standard. Having the motor control and
chiller control in one panel provides better integration and optimization of the two control systems.
For example, the chiller controller can unload the chiller when approaching an overload “trip”
point, so that the chiller stays online.
Table 2 and Table 3, p. 14 can be used to compare the standard electrical features of the chiller
controller with those of other common Eaton Cutler-Hammer
®
starter-only-mounted devices.
Additional starter-mounted metering and motor protection may not be required and could be
considered redundant.These devices are not available for AFDs.

(a)The MP 3000 features Intel-I-Trip overload protection, enhanced custom trip curve development, UL 1053 ground fault, and advanced data logging and
diagnostics.
(b)For low voltage, a Trane-supplied circuit breaker or non-fused disconnect is also required when ground fault is specified.
(c) The chiller controller monitors the motor temperatures of all three phases with one resistance temperature detector (RTD) per phase
(d)For this option, add one or two sets (three RTDs per set) of 100-ohm platinum RTDs to the motor. Contact La Crosse Field Sales Support.
(e) Under/over phase-voltage sensors include volts per phase, kW, power factor, kWh, and under/overvoltage. A required pick on medium-voltage starters.
(f) Three alarm levels are used: warning only, nonlatching (auto-reset), and latching (manual reset required).
