GENERALITIES
The three and four pole change-over switches, with Motorized operation,
allow remote control of change- Over/breaking/disconnection under
load of power circuits in low voltage systems.
COMPOSITION OF THE RANGE
The range of motorized change-over switches is made by 14 sizes of
switches of current rating from 160 A to 3150A, 3 and 4 poles are
available in the COVISYS-S series with switch laid one upon the other
and in the COVISYS-H series with switch horizontally interlocked.
The COVISYS-S series is made by 3 families:

Multi-Switch improves electrical supply continuity. The principle of operation guarantees a higher reliability level than that achieved using a single UPS (on-line with automatic bypass) or several UPS in parallel.
PRINCIPLE OF OPERATION
The Multi-Switch provides electrical distribution and remote management for up to eight network users, powered from either one or two direct mains supplies or UPS or a combination of both.
Multi-Switch can connect each user (up to eight, each with a maximum power demand not greater than 3A), to either of the two power sources (A and B). Load demand is shown on the LCD. See “principle of operation” diagram.
PROTECTION AGAINST POWER SUPPLY FAILURES
If one of the two power sources fails or falls outside specification, Multi-Switch will transfer the connected loads to the second power source (switching is instantaneous even if the two sources are in phase).
PROTECTION AGAINST FAULTS WITH THE LOAD
If a fault occurs with one of the loads (for example due to a short-circuit or overload), Multi-Switch will disconnect the load to prevent disruption to the others.
Multi-Switch protects sensitive installations from both power and hardware faults.

P1, P3 and P5 Switch Disconnectors up to 315 A –
For Absolute Safety
Like T rotary switches, P switch disconnectors are manually operated switching devices without any release or switch mechanism but with a direct link between manual operating element and the contact. The contacts are positively opened on de-energization, and the auxiliary contacts are interlocked opposing contacts.
Switchable "N conductors" and/or "HI21 auxiliary contacts" can be connected to the P1, P3, or P5 switch disconnector with a make and break contact. The auxiliary make contact is always switched as a load shedding contact for control of the contactor. In this manner, the contactor assumes the switching task and the switch-disconnector only needs to disconnect the main current circuit.

The Piller Apotrans takes care of critical loads by automatically and transparently providing an alternative power source whenever the preferred power source becomes deficient. This changeover, occurring within a few milliseconds assures that the load is always fed by the optimum power supply. With Apotrans, redundancy is engineered into the power system infrastructure, giving steadfast confidence in the performance of critical operations. Apotrans provides optimum power to secure the load for continuous operation. Every time the preferred power source fails or its voltage no longer meets specified quality requirements, APOTRANS intelligently switches to the alternate source. APOTRANS automatically or manually returns the load to the preferred source once it is sensed to be stable.
