MTL Process Junction Boxes

Eaton's Crouse-Hinds series MTL Process Junction Boxes are designed for mounting fieldbus wiring components, terminators, F30 Ex ic adaptor, 9320 spur connections, surge protection devices and MTL831 Multiplexer transmitters in order to meet the exacting requirements of process industry customers. They offer plenty of space for termination and wiring, making it easy to install and maintain the fieldbus system.

Our FCS-9000 Junction Box is manufactured from 316 stainless steel to provide the highest level of strength, durability and protection from corrosive chemicals and their vapors.

A wide choice of glands is available, ready fitted to the junction box: stainless steel, nickel-plated brass and plastic, enabling a high quality seal with standard or wire-armoured cables. All glanding is in the base of the enclosure with a minimum of 75mm of clearance between the base of the enclosure and other components. This makes glanding much easier, especially when terminating armoured cable.

FCS-9000 Process Junction Boxes are suitable for Zone 2 and Zone 1 intrinsically safe (Ex i) and increased safety applications.
