Primary Reactor, Reduced Voltage - Eaton Cutler-Hammer AMPGARD Technical Data Manual

Primary Reactor, Reduced Voltage Starters Catalog S510
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.
One vertically mounted current limiting power fuse 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
– Two interposing relays
One set of control circuit
terminal blocks.
Reduced Voltage Structure
One magnetic 3-pole vacuum run contactor with dc operating coil
and electrical interlocks.
Three current transformers.
One medium-duty starting reactor with 50 – 65 – 80% taps.
