We Specialize in  ATEX, Ex, Explosion Proof  & flame proof  Terminal Box . we enable any build according to user specification with optimal fit to any application requirements.  Terminal box comes with suitable ingress protection and wide ambient temperature ranges. Their distinctive construction features facilitate easy installation and maintenance.

Here terminal block is a screw-type electrical connector where the wires are clamped down to the metal part by a screw. It is a connector which allows more than one circuit to connect to another circuit. It often contains two long aluminum or copper strips that are designed to connect different components. Terminal blocks are used to secure and/or terminate wires and, in their simplest form, consist of several individual terminals arranged in a long strip. Terminals are useful for connecting wiring to a ground or, in the case of electrical power, for connecting electrical switches and outlets to the mains. Another terminal type are terminal blocks with screws for holding an inserted cable on one end and a plug on the other end so that the block can be inserted into a female connector (this allows for hot-swapping)

Terminal blocks for “e” increased safety protection in Ex Zone 1 and 2 or 21 and 22

When the installation instructions are followed, the terminal blocks satisfy the requirements for “e” increased safety protection. The terminal blocks are therefore approved for installation in Zone 2 and, in particular, Zone 1, i.e., in the actual Ex area. The latter, however, is only on condition that the terminal blocks are installed in connection boxes. The connection boxes must also be approved for “e” protection and must have at least IP54 protection.

Terminal blocks for “i” intrinsic safety protection in Ex Zone 0, 1, and 2 or 20, 21, and 22

No special approval is required for terminal blocks in applications with “i” intrinsic safety protection. In addition to Ex e approved terminal blocks, standard terminal blocks can also be used here, taking IEC/EN 60079-11 into consideration.

Ex e and Ex i terminal blocks in the same housing

For  ATEX, Ex, Explosion Proof & flame proof Terminal boxes, both intrinsically safe circuits (Ex i) and increased safety circuits (Ex e) can be combined. Safe mechanical isolation and, if necessary, visual separation are prescribed here It must be ensured that individual conductors do not come into contact with conductive parts of the other circuits when the wiring is disconnected from the terminal block.
