HAC Series
AC Load Solid State Contactors
FEATURES
PART NUMBER NOMENCLATURE
The HAC Series Solid State Contactors (SSCs) are designed for control of high power AC loads
such as heaters, motors, lights, pumps, solenoids, transformers, etc., where long life and
reliable AC switching are required and traditional mechanical contactors or relays don't provide
the required life, performance or service levels. The HAC Series offers the latest in AC Solid
State Power control by virtue of Crydom's proven AC power switching technology and control
circuitry. Advanced thermal design provides superior performance for loads rated up to 150
Amps rms from 48 to 660 VAC.
150 Amp AC Load Ratings @ 40ºC ambient with 0.25ºC/W heat sink
Single Pole Single Throw Normally Open operation (SPST/N.O.)
LED Input Status indicator standard
UL & cUL recognized
Required for valid part number
For options only and not required for valid part number
(A) See compatible accessories in TABLE 1.
(B) For maximum ratings use heat sink ratings shown in HAC series derating curves (see product
datasheet).
(C) Load can be wired to either terminal L1 or terminal L2.
MOUNTING INSTRUCTIONS
Mounting on Heat Sink
Mounting on Panel
Please read all installation instructions before using your HAC Series Solid State Contactor (SSC).
Choose one of the two mounting options and follow the instructions.
Locate the panel section on which the HAC Series SSC will be mounted. Panel mount
surface must be clean, bare metal and provide adequate heat sinking capability. (B)
Be sure to use thermal pad or thermal compound between the SSC and the panel.
HAC Series Contactor mounting slots have a diameter of 0.2 in (5.0 mm). Four screws are
needed (not included) to mount the SSC onto panel. Choose screw length considering the
mounting surface and that HAC Series baseplate thickness is 0.125 in (3.2 mm).
Before applying full torque, tighten down all 4 screws until they contact the baseplate.
Then, tighten them to 20 in-lbs (2.2 Nm) starting with one immediately followed by the one
in the diagonally opposite corner. After the first 2 screws are completely tightened,
proceed tightening the remaining 2 screws.
Select adequate heat sink (see thermal derating curves).
Be sure to use thermal pad or thermal compound
between the SSC and the selected heat sink.
HAC Series Contactor mounting slots have a diameter of

Wire Size
Maximum wire size capacity: Input 12 AWG (3.31 mm 2 ) through suggested
mating connector (see TABLE 2), Output 2/0 AWG (67.4 mm 2 ).
Connections
First install Lug Terminal (Item 1 on fig.2) followed by Washer Int. Tooth-Lock
(Item 2 on fig.2) and finally Nut Hex (Item 3 on fig.2)
Terminals
For maximum ratings, for 150 Amp models use Crydom lug terminal TRM3/0 or
other lug terminal with a diameter of 0.375 in (9.52 mm), 2/0 AWG (67.4 mm 2 ) 75ºC
insulation wire installing capable.
Important Considerations
WARNING! Do not try to unscrew Terminal Studs from Product.
Be sure to use input and output voltages within operating ranges.
