Terminal box alternatives

01 Main terminal box.

02 Adapters, Flange with glands; cable sealing end units.

Optional adapters

There is a broad selection of cable termination accessories available to allow termination of one or several cables. The most common ones are explained below.

How to order?

– Check first that the teminal box itself allows mounting of the desired cable and cores (refer to motor type and terminal box type cross reference on previous page)

– If very large cables are used it might be necessary to use a larger terminal box than standard. Select the right cable gland(s) or cable sealing end unit(s) that match outer diamater of the cable(s)

– Select appropriate adapter or flange

– Note that turning the terminal box to a nonstandard position might limit the use of some adapters.

Main terminal box and maximum single core

cross-section

You can select one size larger than standard terminal box if a larger single cross-section is needed.

The standard sizes of the main terminal box are listed in the following table. The terminal box is named according to its current-carrying capacity, from 120 to 1200. Check also the capacity of the cable entry to make sure that the cables fit.

A larger terminal box can be ordered with variant code 019.

Optional adapters

To allow easy termination of cables entering the terminal box from above or below, an angle adapter is recommended. These are available for motor sizes 280 and above and can also be used to allow the mounting of several cable sealing end units or gland plates. For exact suitability on a certain motor size, refer to the ‘terminal box opening’ column in section Standard terminal box.

Cable sealing end units

As an alternative to flanges and cable glands, cable sealing end units can be used. These allow more space for spreading the cores for easy termination.

Cable sealing end units have rubber-sealed entries for one of two main cables. In addition, there are two plugged M20 holes for auxiliary cables.

Auxiliary terminal box

You can equip motors from frame size 160 upward with one or several auxiliary terminal boxes for connection of auxiliaries like heaters or temperature detectors. The standard auxiliary terminal box material for motor sizes 280 - 450 is aluminum and for 160 - 250 cast iron. For 280 - 450, cast iron as box material is also available as an option.

Connection terminals are of spring-loaded type for quick and easy connection. These are suitable for up to 2.5 mm2 wires.

Auxiliary terminal boxes for 280 - 450 are equipped with an earthing terminal. The first auxiliary terminal box is located on the right-hand side at D-end as standard.

The standard cable entry size is M20 for the aluminum box and M16 for the cast iron box, and the number of entries depends on the terminal box type and the number of selected auxiliaries.
