Cartridge pressure switch

Type ACB and CCB

Fixed setpoints

Pressure controls ACB and CCB are compact disc type pressure switches with fixed 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 different 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 fittings for soldering or direct mounting

• Spades or cables

• Stripped ends or customer specific 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

Cartridge pressure switch, type ACB and CCB

Lifetime

Switch type:

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 specifications at any time without prior notice.
