CONTA-CONNECT

Stud connection system HSK

The newest generation of stud terminals from CONTA-CLIP offers secure con-

nections for all energy-transmitting applications. Depending on the conductor

cross-section, stud terminals can be used with threaded studs from M5 to

M12. The rated current ranges from 76 A to 269 A with a rated voltage of

1000 V. The wire connection range is from 0,2 mm² to 120 mm². Wires with

crimped cable lugs are applied to threaded bolts and then connected securely

by tightening the hex nut. Optimal security is guaranteed by the low voltage

drop and by the use of self-extinguishing material with a V0 (UL94) flammabili-

ty rating.

Designed for mounting onto TS 35 DIN rails, the stud terminals can be adapt-

ed with accessories such as TW partitions and AD covers to suit application

requirements. These products are easy to use. They also stand out with their

cost-optimized line of accessories which results in reduced storage costs and

assembly times.

Base terminal HSK

CONTA-CLIP stud terminals can be arranged as

required on standard TS 35 DIN rails in accor-

dance with EN 60715.

a Partition plates TW

Special TW partitions can be securely snapped into

the terminal housing. This allows for good visual

and electrical separation of the terminals. In addi-

tion, they are ready for fitting with snap-on covers.

b

Covers AD

The AD covers can be snapped on, simply and securely, to

the matching clips in the partitions. In this quick and reli-

able way, touch-safe protection of the terminal points is

always guaranteed.

c End stop ES 35/K/ST

The ES 35/K/ST end stop grips both sides of the DIN rail

with steel clamps. They are a secure method of mechanical

attachment in terminal rail design. The plastic PA 6.6 hous-

ing of the brackets encapsulates the metal parts.

Labelling | Marking

The stud terminals have a labelling surface which is opti-

mally suited for our Pocket-Maxicard PMC (PMC BSTR

6/30) standard marking systems.

Handling

1 Stud terminals:

Up to four wires can be connected easily. Cable lugs are

crimped onto the wire ends to facilitate the connection. The

cable lugs should be aligned opposite each other when there

are multiple lugs per side. When the nut is tightened, the flats

of the cable lugs clamp together and a secure connection is

ensured.

2 Stud terminals:

Cable lugs are crimped onto the wire ends to facilitate the con-

nection. The cable lugs are placed on the studs between the

shake-proof washer and the busbar. The cable lugs should be

aligned opposite each other when there are two lugs per stud.

When the nut is tightened, the flats of the cable lugs clamp

together and a secure connection is ensured.

High-power stud terminals HSK

Handling and accessories

The use of TW partition plates

The HSK…B single-stud terminals and the HSK…B/B twin-

stud versions make use of two TW partitions. The partitions

can be adjusted to the rated cross-section by using the prede-

termined breakage points. For your further assistance, the

TW partitions list the cross-section range and additional

dimension lines. Remember that the clearance and creepage

distances for a rated voltage of 1000 V, dependent on the

corresponding cross-section, must be followed.

Snapping on the partition plates to the HSK high-

power stud terminals

You can snap on the TW partition plates and the HSK stud

terminals by using the locking pegs on the partition. The

pegs lock into the foot of the stud terminals.

Using the AD covers

An individual AD cover is available for each width of stud ter-

minal. Their length takes into consideration the creepage and

clearance distances on the twin-stud terminals. If the covers

are to be used with the one-stud versions, you can shorten

the cover by breaking it along the breakage points. For your

further assistance, the AD covers have additional dimension

lines on them. Locking pegs are used to mount the AD cover.

The cover snaps in securely from above to the TW partition

plates. Thus a high degree of touch-safety is guaranteed.

High-power stud terminals HSK B...B/B

192192

The newest generation of HSK B…B/B stud terminals from CONTA-CLIP offers secure connec-

tions for all energy-transmitting applications. Depending on the wire cross-section, stud terminals

can be used with threaded studs from M8 to M16. The rated current ranges from 192 to 415 amps,

with a rated voltage up to 1000 volts. The wire connection range is from 6 mm2 to 240 mm2. Wires

with crimped cable lugs are applied to threaded bolts and then connected securely by tightening

the hex nut. Optimal security is guaranteed by the low voltage drop and by the use of self-extin-

guishing material with a V0 (UL94) flammability rating. Designed for mounting onto TS 35 DIN

rails, the stud terminals can be adapted with accessories such as TW partitions and AD covers to

suit application requirements.

Cross-connections/Potential distribution

With neighbouring stud terminals, it is possible to implement

potential distribution over two-pole QS cross-connection

rails. The cross-connections are each designed for the rated

the cable lug over the stud. When using the cross-connection

rails, do not use the partitions between the individual termi-

nals. A cover over the terminals is not possible here.

Unlocking the DIN rails

The size of the terminal feet allows for a secure fit on a DIN

rail with a thickness of at least 1.5 mm. A spring slider in the

foot is used for a simple, quick snap-on and snap-off from

the DIN rail.
