• Overload Relays — Bimetallic Ambient Compen-
sated
Features include:
– Selectable Manual or Automatic Reset operation.
– Interchangeable Heater Packs ± 24% to match
motor FLA and calibrated for 1.0 and 1.15 service
factors.
– Heater packs for Size 00-0 overload relays will
mount in larger Size 1 and 2 overload relays —
useful in derating applications such as jogging.
– Single phase protection – Class 20 or 10 trip time.
– Electrically isolated NO - NC contacts (pull RESET
button to test).
– Visual trip indication
– Integral load lugs allows field wiring prior to heater
pack installation.
– NEMA Sizes 5-9 use Current Transformer with 32
Amp overload. Size 5 uses 300:5 CT, Size 6 uses
600:5 CT, Size 7 uses 1000:5 CT, Size 8 uses
1500:5 CT, and Size 9 uses 3000:5 CT.
• Magnet Coil — Encapsulated dual voltage/fre-
quency – color coded and permanently marked with
voltage, frequency and part number.
A two-piece spring latch contactor design makes coil
removal or replacement fast and simple for Sizes
00-2.
The NEMA Size 3-5 features a quick change coil
assembly which makes coil removal and replacement
fast and simple.
Coil terminals are located on top for easy accessibility.
The Size 00 and 0 contactor magnet coils have three
terminals, permitting either top or diagonal wiring —
European or U. S. style starters can be replaced
without changing wiring layout.
The NEMA Sizes 6-8 features a special DC feeder
group for coil feeding. This system allows AC or DC
applied voltage, low noise and low inrush and holding
consumption.
The NEMA Size 9 coil is 110V dc/120V ac (Rectified).
AC or DC magnet coils.
• Contacts — Long life twin break contacts provide
excellent conductivity and superior resistance to
welding and arc erosion. Generously sized for low
resistance resulting in extended life.
