Control Units

Test Kits

Every control unit is equipped with a test receptacle that can be used with a test kit. Tests

performed by test kits are only functional tests designed to electrically test the operating integrity of

the control unit, the flux transfer device and the mechanical operation of the circuit breaker. Tests

are not designed to calibrate the circuit breaker. Calibration can only be done at the factory.

Load monitoring (R)

Option R provides two independent static contacts which operate when the current exceeds

adjustable pickup limits:

n When the current exceeds the limit Ic1 (or Ic2), the contact C-R1 (or C-R2) closes following an

inverse time characteristic A.

n When the current drops below the limit Ic1 (or Ic2), the contact C-R1 (or C-R2) opens with

constant time delay (10 seconds) B.

These contacts can be used for load shedding, alarms, indications, etc.

Voltage 240 Vac max.
