E Improved Performances

In addition to the increased number of contact combinations, the NEW Gewiss

contactors guarantee high technical performance and electrical endurance for the

operating frequency according to the utilization category and power of the device.

24V AC/DC and 230V AC-220 DC control coil voltage versions available.

Additional Accessories

The NEW Range of contactors can be equipped with Gewiss auxiliary contacts to

enable remote indication of the contactors status. It is also possible to use sealing

terminal covers which prevent access to terminal connections and therefore

remove the possibilities of direct contact with live parts.

90 AM RANGE

Silent Operation

With thanks to the new technology of the coil the entire range is suitable for many

applications that require silent operation, for example: Hospitals, Hotels, Retirement

homes etc.

CIRCUIT IDENTIFICATION

every contactor has a clear label holder that enables circuit

identiication for each device.

MANUAL CONTROL VERSIONS

On the front of every device there is a mechanically

operated indicator that represents the position of the

internal contacts:

- neutral colour: un-switched contacts

- red colour: switched contacts

HARMONISED RANGE

The new CTr range can be perfectly integrated with the

other geWISS protection devices, providing a pleasant

aesthetic result.

VISUAL INDICATION

All manual control contactors have a lever switch on the

front of the device that enables manual control of the

operational functions:

- Automatic

- Isolate (permanently switched of)

- Temporary operation

UTILIZATION CATEGORIES

90 AM RANGE


In general, the technical data of Gewiss contactors refer to the AC-1 or AC-7a utilization category. If the type of electrical load

doesn’t belong to these categories, the current and as a consequence the power of the load, must be derated according the

following table.

START

A typical automatic control circuit for start-stop of an engine consists of a device

for the protection of overcurrents (MCB or motor protection switch), a contactor (to

allow opening and closing of the power circuit) and an auxiliary circuit consists of

buttons which energize and de-energize the contactor’s coil (typically a NO button

start and a NC stop button such as GW 96 565)

The choice of the contactor most suitable for this type of application must not only be inluenced by the power of the engine

but it’s important even to consider the utilization category in order to know its electrical endurance in reference to the number

and frequency of operations. In the EN 60947-4-1 standard there are 4 utilization categories regarding to motor control, exactly:

• AC-1 for switching of slightly inductive loads (e.g. electric heating, power distribution)

• AC-2 for starting, switching of, plugging, inching of slip-ring motors (e.g. hoisting, handling, crusher, rolling-mill)

• AC-3 for starting, switching of running of squirrel-cage motors (e.g. pumps, fans, air-conditioning, conveyors, presses etc…)

• AC-4 for starting, switching of, plugging, inching of squirrel-cage motors (e.g. hoisting, handling, crusher, rolling-mill)

The most common type of method to start and stop the running of a motor corresponds to the AC-3 category i.e. the control

device drives the starting current and stops the running of motor when the motor is supplied by the rated current.

In the case of AC-4 utilization category, the contactor must be oversized because it works under heavy-duty conditions since

switching of of running happens during start-up period of the engine instead during regular working period.

Below there is an example for the choice of the most suitable contactor considering every factor described previously:

• Squirrel-cage motor control (AC-3 utilization category)

• Operational voltage: 400V three-phase

• Motor power: 11kW

• No. of operations: 100 per day

There are two options for motor controlling:

1.CTR40: at max operiting power of 11kW, max number of operations is 150,000. Therefore the contactor’s lifetime is 150,000 /

100 = 1,500 days.

2.CTR63: from durability diagrams it’s possible to know the number of operations depending on motor power that is about

270.000 operations. Therefore the contactor’s lifetime is 270,000 / 100 = 2,700 days.

Versions with manual control have on the front face a built-in toggle handle switch which enables to set the operating mode of

contactor.

A: AUTOMATIC operating mode, working as normal contactor. Therefore the switching of contacts happens when the coil is

energized and is disenergized.

O: PERMANENT SWITCHED OFF control voltage mode, the contacts are locked mechanically.

I: TEMPORARY RUNNING mode. The contacts switch when the control voltage is not applied. When the control voltage is

applied the toggle handle switch is automatically set to position A maintaining the previuos contacts status.

Versions with manual control are used when it’s necessary to switch the contacts without considering their status and leaving

out the basic function of normal contactors. In fact it’s always possible to switch the contacts even when control voltage is not

applied.

Contactors with manual control enable switching depending on tarif (selection of most convenient tarif ). Moreover they are

suitable to test the working of product before starting or for maintenance operations (such as the replacement of lights) to ensure

the safety of the operator. In the end it’s possible to avoid the installation of change-over switch (manual/auto) or three-way line

switch (manual/0/auto) often required as accessory for the control of motor, pump and fans.
