The CA 441 monitors leakage on either:
- up to four individual pumps with combined alarms (e.g. XFP pumps in the PE1 & PE2 series), or
- one individual pump with separate alarms for the cable connection chamber, the motor compartment, and the inspection chamber (e.g. a large XFP, AFLX, or VUPX pump)
It features a CAN-bus interface for managing a local or remote connection to the PC 441 monitoring/controller device.
