Secure Ignition Protection Categories

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.


An explosion occurs when oxygen (air), a flammable substance and an ignition source meet in a specific ratio to each other. Ignition protection categories counteract the origination of explosions; here, these categories designate measures with the goal of preventing ignition sources – for example, in production systems.

Principles of Explosion Protection

Everything worth knowing about Ex protection at a single glance.

Overview of the Ignition Protection Categories

In environments with an explosive atmosphere, ignition protection categories serve to prevent ignition by not reaching impermissibly high temperatures. The ignition protection categories are distinguished according to the type and function of the equipment and the probability an explosive atmosphere will occur.

Electrical equipment is subject to the provisions of IEC 60079-0 (gases and vapors), IEC 61241-0 (dust) and EN 13463-1 (non-electrical equipment). The equipment must be accepted by an approved testing office, for example by the Physikalisch-Technische Bundesanstalt [German national test authority] (PTB).

What happens during an explosion, which factors are important, and what protective measures are available? Everything you need to know about ATEX, Ex zones, ignition protection categories, etc.

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.

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.

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.

Ignition Protection 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.

Directives, Standards and Regulations

The requirements for electrical equipment for hazardous locations are multi-layered: National and international determinations, guidelines and standards must be complied with to achieve the highest possible level of safety. We give you an overview of the most important regulations and recommendations, such as the ATEX directive.
