Cartridge pressure switch
Type ACB and CCB
Fixed setpoints
Pressure controls ACB and CCB are compact
disc type pressure switches with xed setpoints for long-standing use in refrigeration
and air conditioning systems. They provide
automatic or manual reset limit protection.
The small size, lightness and high degree of
protection means that it can be mounted
directly on the refrigeration systems.
The cartridge switch is available with dierent
pressure settings and pressure connections to
suit customer requirements.
All these features reduce installation costs and
save space.
Features:
• Wide range
• Fixed pressure set points
• Automatic or manual reset
• Various port ttings for soldering or direct
mounting
• Spades or cables
• Stripped ends or customer specic electrical
plug
• Open or water-proof (IP65) version
• Type ACB for use as high and low pressure cut
in and cut out as well as fan cycling
• Type CCB available for CO2 refrigerants
• Compact design and easy to install

SPST auto reset, Normally open
Pressure setting : max 3 MPa
As general rule, ACB pressure switches are capable to cover applications requiring cycling from 100000 to 1500000
cycles dependent on current load. The exact number of cycles in any of given application is to be determined by
appropriate testing.
Manufacturer reserves the right to change or modify specications at any time without prior notice.
SPST auto reset, Normally close – up to 100000 cycles
SPST manual reset, Normally close – 10000 cycles
SPDT auto reset – up to 100000 cycles
SPDT manual reset – 10000 cycles
