Cross Connection Accessories

Various functional requirements can be achieved with the aid of cross connecting systems. Techna offers different types of cross connecting accessories which includes a variety of temporary shorting links, permanent shorting links, shorting studs, shorting sleeves, multi-pole comb links and pre-assembled shorting assemblies.

When permanent shorting links are installed, TTEC Terminal Blocks are safe from accidental contact because the links rest below the top surface of terminal block.

Shorting / Comb Link's amperage is lower than the rated current of the respective terminal block, therefore the applied current must not exceed the maximum current value of the terminal block.

TTEC Shorting Links
In spring clamp type terminal blocks cross connections are achieved by using different type of push in type shorting links. The cross connecting shorting links need to be inserted into the rectangular slots provided in the current bar of the terminal block.

- 2 way insulated push in type Shorting Link is useful to short 2 consecutive Terminal Blocks.
- For shorting any two terminal blocks in between series of 10 terminal blocks, insulated push in type Wire shorting link is used.
- Alternate Shorting Links is convenient when cross connection is required between Alternate (non consecutive) terminal blocks.

TTEC Insulated Push-In Type Shorting Links are specially designed for use in TTEC Spring Clamp Terminals. Besides providing shock protection, these links simplify the task of cross connection.

The link has to be inserted into the slot provided in the current carrying part of the terminal to bridge with adjacent / alternate terminals. Choice of adjacent and alternate TTEC Shorting Links are available.

Pre Assembled Shorting Links are ideal choice for quick permanent cross connections of terminal. Simply insert the link assembly and tighten the screws for quickest cross connection. Available in 2 / 3 / 4 / 10 / 100 pole assembly, the Pre Assembled Shorting Links have following advantages :

- Eliminates possibility of losing sleeves / screws while cross connecting because of captive screws used
- Saves considerable time for cross connection
- Simplifies the task of cross connection, with ease of use.

The TTEC Pre-Assembled Shorting Links, with captive sleeves and screws, are recommended for quick cross connections. These 2, 3, 4 and 10 pole assemblies of links and sleeves have the following advantages:
Cross connection task is simplified.

Eliminates possibility of losing sleeves or screws while cross connecting.
Saves considerable time in cross connecting.

The TTEC Series Side Ways Shorting Links are used for cross connection wherever terminals in assemblies cannot be cross connected with the aid of conventional TTEC Shorting Links, Sleeves / Studs. The links are insulated which makes them shock-proof. TTEC Side Ways Shorting Links are available in 2, 3 and 4 pole lengths. Choice of temporary / permanent Side Ways Shorting Links are available.
