Introduction
Pact Series
Future-proof your installation with Schneider Electric’s low-voltage and medium-
voltage Pact Series. Built on legendary Schneider Electric innovation, the Pact
Series comprises world-class circuit breakers, switches, residual current devices
and fuses, for all standard and specific applications. Experience robust
performance with Pact Series within the EcoStruxure-ready switchgear, from 16 to
6300 A in low-voltage and up to 40.5 kV in medium-voltage.
Intended Use
The EvoPact vacuum circuit breaker is intended exclusively as a switching unit in
air-insulated medium-voltage switchgear. It may only be used in the scope of the
specified standards and the switchgear-specific technical data. Any other use
constitutes improper use and may result in danger and damage.

3 Regulations and Provisions
Safety Provisions
The work described in this Technical Instruction manual may only be performed by
specialist electricians who have proved their experience with the EvoPact circuit
breaker and the EN 50110-1 standard.
Applicable standards and regulations:
• The locally applicable accident prevention, operating, and work instructions
must be complied with
• Installation: IEC 61936-1/HD 637 S1: 2010
• Operation of electrical equipment: EN 50110-1
Read these instructions carefully before you work on the circuit breaker, and
perform the work detailed in it according to the descriptions. Do not perform any
work on the circuit breaker which is not described in this Technical Instruction
manual.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Before starting work on the circuit breaker, de-energize the system, verify it for
zero voltage and earth the system according to the applicable safety rules
pursuant to EN50110-1.
Failure to follow these instructions will result in death or serious injury.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Before performing work on the circuit breaker, switch off the auxiliary voltage
and prevent it from reclosing.
Failure to follow these instructions will result in death or serious injury.
WARNING
HAZARD OF FAST MOVING PARTS
Before commencing work, release the energy-storing device by performing the
operating sequence OFF-ON-OFF.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.

Motor charging time ≤12 S
* Rated frequency according to specification on rating plate (50/60 Hz)
Auxiliary Switches
Auxiliary switches are always actuated directly by the switch shaft via an
intermediate linkage. Their position always corresponds to that of the main
contacts. As standard, the circuit breaker is equipped with two auxiliary switches
with 8 contact elements each.
The switching functions have been set in the factory according to the wiring
diagram.
Anti-pumping Relay (optional feature)
If an ON and OFF command is simultaneously and permanently present at the
circuit breaker, the latter returns to its initial position after closing. It remains in this
initial position until the ON command is issued a new. This helps preventing
continuous closing and opening (pumping).
