Chiller Starter (AMPGARD) Technical Data TD02003003E Effective: October 2006
Reduced Voltage Autotransformer Starters Catalog S610
Non-Reversing
Mounted in the Medium Voltage Section
●
Three incoming line connectors.
●
One drawout 3-pole gang-operated line isolation switch assembly
with isolating shutter, external operating handle interlocked to
prevent opening the medium voltage compartment door until the
isolating switch is open and grounded.
●
Three vertically mounted current limiting power fuses with pop-up
blown fuse indicators.
●
One magnetic 3-pole vacuum contactor with dc operating coils
and mechanical interlock to prevent opening the isolation switch
when the contactor is closed.
●
One control power transformer (115-volt secondary).
●
Two CPT primary current limiting fuses.
●
One control circuit secondary fuse.
●
One run-test circuit.
●
Four electrical interlocks (2NO, 2NC).
Mounted in the Low Voltage Compartment
●
One control panel with:
– One MP-3000 motor protection relay
– Three interposing relays
●
One set of control circuit terminal blocks.
Reduced Voltage Structure(s)
●
One magnetic 3-pole vacuum run contactor with dc operating coil
and electrically and mechanically interlocked with the starting
contactor.
●
One magnetic 2-pole vacuum start contactor with dc operating coil
and electrical and mechanical interlocks.
●
Three current transformers.
●
One medium-duty starting autotransformer with 50 – 65 – 80% taps.
●
Three distribution class lightning arresters for high voltage stress
protection on the transformer zero tap.
