Danfoss Electronics ACB, CCB Data Sheet

Data sheet

Cartridge pressure switch
Type ACB and CCB

Pressure controls ACB and CCB are compact disc
type pressure switches with xed set-points 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 dierent
pressure settings and pressure connections to
suit customer requirements.

All these features reduce installation costs and
save space.
