Description

The inverter motor starter Atex & IECEx has been designed to inverter the turn of motor with guarantee and protection in high explosion risk zone.
It’s used to control the electric motor switching, with two turns and switching off, besides to protect it against overloads thanks to the thermal relay.
This is achieved with two phase contactors and a thermal relay to protect the starting power peak.
The Ex motor starter components, are protected inside of an Atex & IECEx enclosure, IP66 made with stainless steel 304L.
This enclosure has a specific design, being antirust, waterproof and with IP66 protection. It has a protection “Ex e” and “Ex d”, being possible to use it in zones with high explosion risk outdoor and rust.

The rated voltage is 690V and the rated current is from 12A to 38A.
The power for which the Ex motor starter has been designed is between 4 and 18.5 kW.
It can work between two temperature ranges, which give it a higher use capacity.

-20°C≤ Ta ≤60°C
-20°C≤ Ta ≤40°C

Regarding the enclosure Atex & IECEx :

The joint between the cover and body, is designed to secure a really high degree protection IP66.
It has a “Ex e” protection, to use it in zones 1, 2, 21 and 22 with explosive atmospheres with dust and gas.
It includes three cable glands in nickel plated brass with “Ex e” in M25.

Discover the advantages

Selecting of the motor turn with safely.
This Ex motor starter allows a faster switching on after a thermal relay’s trip.
It will have a longer use thanks to thermal relay, which avoids sudden motor stops and therefore machine stops.
It’s possible to get the coil with low voltages, controlling high capacity motors with a low tension circuit.
There are so much voltage and current possibilities to choose the Ex motor starter. 12A to 38A.
It can be manufactured with AISI 316L for marine atmospheres.
Great versatility and possibilities.
