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.

NOTE: Operating reliability and service life depend on correct operation.

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.

Information about the power consumption of solenoids and the motor is available

from the manufacturer. The auxiliary voltage data is required to this effect.

Times for solenoids and motor

Minimum command time OFF el. tripping 100 ms

Minimum command time ON el. closing 100 ms

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).
