Explosion Proof Push Button

Explosion Proof Push Button

Our explosion proof push button is used in almost all hazardous areas where machine functions are activated by means of a button. The Exd push button is flexible and in addition to a large number of actuating elements it offers a junction box to facilitate a safe and convenient installation of the module into a control panel. All contacts in the switch modules are self-cleaning and the opening contacts have positive opening operation. The conductors are connected by means of terminals on the back of the module which have an increased safety level. The easy installation of the actuating elements without tools ensures conformance to the high IP degree of protection. Use in Zone 1 and 21.

Our wide range of explosion-proof pushbuttons is designed to warrant they meet the usage requirement. The explosion-proof push buttons ensure that they can maintain the power distribution requirement, signal, and monitor other electrical functions that they should perform inside the hazardous environment of the factories.
