ProductsSwitch-disconnectors OT

OT switch-disconnectors are available from 16 A to 600 A up to

1000 V DC. OT series from 16 to 40 A are an ideal solution for string

boxes in residential applications and/or residential inverters where

reliable isolation is required and safety is a must.

OT series from 200 to 630 A are a cost-effective solution either for string

boxes in commercial/large-scale installations or inside central inverters

where they provide reliable isolation while simplifying maintenance and

improving overall safety.

Main features include:-Reliable position indication

-Contact opening non-dependent on speed of operation

-Wide range of accesories

Product noteTmax PV: photovoltaic rangeT Generation

Tmax PVincludes all the advantages of the T Generation:

excellent performance-dimensions

vast and complete range of accessories for all requirements

complete remote control

The average generating capacity of photovoltaic installa tions

is increasing every day, in all parts of the world.

When it comes to large photovoltaic production installations

(over 200 kWp), the power installed has continued to increaseat an incredible pace over the last period, and at a higher rate

than that of small and medium-sized installations.

When the power generated by a photovoltaic production sys-

tem exceeds a certain level and use of a low voltage switch-

disconnector is required, Tmax PVmoulded-case switch-

disconnectors are suitable for the purpose.

Tmax PVis the latest T Generation product: from 0 to 1600

A , up to 1100 V DC.Tmax PVpossesses IEC 60947-3 certification.

Tmax PVincludes 6 different sizes: from the compact T1(which can be mounted on DIN rail) to the high-performance

T7, avai lable in the two versions, wi th lever operating mecha-

nism and motor operator.

Tmax PVoperating devices are the first moulded-caseswitch-disconnectors for high direct voltage available on the

market.

They are of certa in interest for all types of photovol taic instal-

lation, where they are the ideal answer for every disconnect-

ing requiremen.

Tmax PVmoulded-case switch-disconnectors can be used in

both parallel switchgears and inverter switchgears.

When used in inverter switchgears, Tmax PVmakes it abso-lutely simple to coordinate the direct side and the alternate

side: the same circuit-breaker can be used for both the DC

and AC sides.

Moreover, Tmax PVequipment, which are manufactured

and tested in accordance with Standard IEC 60947-3, can

be used for mixed resistive-inductive loads in all low voltage

installations with 1100 V DC and 1600 A rated current.

Tmax PV: photovoltaic range

T Generation

The widest choice, thanks to Tmax PVfordisconnecting the DC side of the inverter, fromjust a few Amperes to 1600 A rated current.ABB is already a partner of some of the mostimportant inverter manufacturers in the world.

5/6

Examples of other applications in which Tmax PVswitch-

disconnectors can be efficiently used:

Electric traction

at the present time, public urban transport vehicles (trolley-

buses, streetcars, subway trains) often run on DC power at

600 to 1000 V voltage ratings

UPS applications

use of uninterruptible power suppliers is becoming more

Since it is small in size, T1D PVcan be

easily installed in the parallel switchgear(also called combiner box).

T1D PV

From T1D PV to T7D PVUp to 1100 V DC

Inverter

From T1 to T7(also with residual current protection)

Transformer

and more widespread in various types of installation: hospi-

tals, for emergencies (lights, alarms), servers, data cent-

ers...

Special industrial applications

such as: electric arc furnaces, electric welding systems,

metal refining plants (aluminium, zinc)

The order codes for TMAX PV are listed in the table

below:

As described, the switch-disconnectors are always sup-

plied with front terminal clamps for copper cables or copper/

aluminium cables: moreover, depending on the size, they are

also complete with accessories, such as insulating plates,

terminal covers or phase separators.
