Fixed type This type of ACB has no draw-out cradle and is designed to be directly mounted in the switchboard. Terminal arrangements ■ Main circuit terminals The ACBs come standard with horizontal terminals. The user can change horizontal terminals to vertical or front terminals using optional attachments for any last minute alterations. £Horizontal terminals £Vertical terminals £Front connections ■ Control circuit terminals Control circuit terminals are front located to allow easy wiring/access. • The terminal blocks (for auxiliary switches and control circuits) are positioned on the top of...

Spring Charged Operation Manual charging type For this type of ACB, the closing springs are charged by means of the spring charging handle. ON/OFF operation of the ACB is performed by means of ON/OFF buttons on the ACB. ■ Charging the closing springs Pumping the spring charging handle by hand charges the closing springs. ■ Closing the ACB Pressing the ON button on the ACB closes the ACB. ■ Opening the ACB Pressing the OFF button on the ACB opens the ACB. The ACB cannot be closed as long as the OFF button is pressed. Motor charging type For this type of ACB, the closing springs are charged...

[ Instantaneously-rated shunt trip device The instantaneously-rated shunt trip device allows the ACB to be opened when an external protection relay against overcurrent or reverse power is activated. Auxiliary switch 1C is used as the anti-burnout switch. This instantaneously-rated shunt trip can be fitted with undervoltage trip to the same ACB.

Over-current Releases (OCR) TemPower2 economical series are provided with the OCR, which can be operated with only two dials, one for selecting the rated current and the other for selecting a protection characteristic. Available characteristics include long time-delay trip, short time-delay trip, instantaneous trip, ground fault trip, pre-trip alarm (optional), and N-phase protection trip (optional). ©Ground fault trip function I GF| The peak value sensing is used (the residual current of each phase is detected). The GF pick-up current is set at 20% of the rated current [/n] with 0.2 sec....
