General description

The thermal overload relay TA 200 DU V1000 is offered in 6 different current ranges: 66 - 200 A.
The tripping function is ensured by 3 current-dependent, delayed overload triggers on bimetal basis.
The thermal overload relay can be set to the consumer rated current by a adjustment knob on the front.
The reset after a release is selectable between hand (Man) and automatic reset (Aut). The manual control reset button can also
be used to turn off.
The settings R and RO can be selected:
Safety note:

Transport, storage


ABB overload relays are accordingly packed ex factory for the in each case agreed upon transport mode.

Avoid blows and impacts.

Pay attention to possible damage of the packing or of the device.

Store the device dry and weather-protected.

Protect the device against dirt.

Installation

Mounting, electrical connection and start-up are only to be done by trained technical personnel. Adhere to the unit-referred con-
ditions and specifi cations of the manufacturer. In the case of violation the protection of the explosion proof motor/consumer is no
longer upright.
Devices of the series TA 200 DU are suitable for attachment to ABB contactors A145 and A185.
Detailed information on the individual combinations can be found in the co-ordination tables. These are available on the Internet.
To connect insert the angle brackets into the contactor clips, hook up the plastic hooks and tighten the locking screws.

Test before commissioning

Press reset – and switch off button for resetting of relay.
By pressing the test release slide, the device trips.
The contact 95-96 opens, the contact 97-98 closes.
Red contact position indicator indicates off position.

Operation


Setting of the motor rated current on the front adjustment knob. Adjust the desired rated current value on the head of
the arrow.

The tripping period at the coordinate points I
of the motor. Whether this requirement is fulfi lled, must be examined using the tripping characteristic.
The appropriate tripping characteristics are contained in this documentation. They can also be requested from the
manufacturer.

Motors for heavy starting (ramp-up time > 1.7 x t
Design Test Certifi cate for EEx e - motors by start up monitoring.

All 3 main current paths must be fl owed through by current, in order to achieve the indicated equipment characteristics.

Operate only in closed areas without less favourable operating conditions (e.g. dust, corrosive steams, damaging ga-
ses).

Suitable encapsulations are to be foreseen in dusty and damp rooms.

In the case of Ex applications proof of the effectiveness of the installed protection devices is required before start-up!
