Interview with Benjamin Böhm on the Pro 2 Power Supply in the Ex Area

Small, efficient, communicative – these features describe the Pro 2 power supply. Greater networking, rising energy costs and growing customization require smaller, more economical, faster and more flexible solutions in control cabinets – especially in the Ex area. This is where the Pro 2 can be used in Zone 2. Benjamin Böhm, Global Industry Manager Mechanical Engineering at WAGO, reveals the advantages in the cav interview.

Topics and Solutions for Today and Tomorrow

Directives, Standards and Regulations

Electrical equipment for explosion-endangered areas must meet numerous criteria. WAGO will introduce you to the most important regulations and recommendations.


Zone Classification

Depending on the type of materials that occur, hazardous locations are not equally at risk. The frequency and duration of occurrence of one of these substances give rise to the different protective requirements for operating equipment.

Ex Protection Measures

Who needs explosion protection? To whom does explosion protection apply? What must be noted here? And what is constructive explosion protection? WAGO has compiled answers to the most important questions for you.

Device Groups

Like the devices, gases, vapors, and dust are divided into various groups according to their properties. This division simplifies the right selection of devices for the various gases, vapors, and dusts.

Types of Protection

Only equipment protected against explosion is permitted in Ex areas. Ignition protection categories are constructive and electrical measures for equipment and qualify as secondary explosion protection.

Ignition Sources

If an atmosphere subject to explosion cannot be prevented in a work area, secondary explosion protection is brought to bear. Secondary measures include prevention of any ignition sources in the Ex area.

What Is an Explosion?

Ex|plo|si|on; -s <lat.> (explosio) means "escaping under pressure." What happens during an explosion, which factors are important and what protective measures are available? You will learn everything you need to know about explosion protection right here.
