Industry Risk

Fire Exposure in Electrical Enclosures

Electrical cabinets contain power distribution systems, control components and sensitive electronics within confined spaces.

Overheating, short circuits or electrical faults can initiate ignition inside the enclosure. Due to the limited volume, fire can escalate rapidly before manual intervention is possible.

Consequences may include:

Early detection and residue-free suppression are essential in enclosed electrical environments.

Common Ignition Sources

Typical Fire Hazards in Electrical Cabinets

Electrical enclosures present concentrated ignition risks. Because cabinets are enclosed, fire intensity can increase quickly without immediate suppression. Primary ignition sources include:

Arc flash events caused by electrical faults

Overloaded circuits or thermal buildup

Short circuits and insulation failure

Component overheating in confined spaces

Protega Fire Suppression Systems

Non-Conductive and Compact Protection

Protega systems for electrical cabinets are typically configured using clean agent (FK-5-1-12) suppression.

How Our Systems Work

Direct and Indirect Detection Technologies

Protega fire suppression systems can be configured as direct or indirect systems depending on enclosure layout and suppression strategy.

Protega uses a heat-sensitive polymer detection tube as primary detection technology.

Operating Principle:

This configuration:

In a direct system, the pneumatic detection tube performs a dual function: it acts both as the fire detection element and as the discharge line for the extinguishing agent.

The heat-sensitive polymer tube is routed throughout the CNC enclosure, positioned near identified risk zones such as spindle assemblies, tooling areas and lubrication components. The tube is continuously pressurized (approximately 20 bar).

When exposed to flame or critical radiant heat:

Because discharge occurs exactly where the highest temperature is detected, suppression is highly localized and immediate.

In an indirect system, the pneumatic detection tube functions solely as the fire detection element. It does not discharge the extinguishing agent.

The heat-sensitive detection tube is routed throughout the CNC enclosure near identified risk zones. The tube remains continuously pressurized (approximately 20 bar).

When exposed to flame or critical radiant heat:

Unlike the direct configuration, the extinguishing agent is not released through the rupture point itself. Instead, it is distributed through strategically positioned discharge nozzles that are engineered based on enclosure geometry, airflow patterns and risk concentration areas.

This enables controlled and volumetric suppression within the protected compartment.

Agent selection

Suppression Agents for Electrical Enclosures

Agent selection is based on application-specific fire risk assessment.

FK-5-1-12 Clean Agent

In electrical cabinets and enclosed technical compartments, FK-5-1-12 is commonly applied where clean, residue-free suppression is required.

The agent suppresses fire primarily through rapid heat absorption, interrupting the combustion process without reducing oxygen concentration to unsafe levels.

Technical characteristics:

FK-5-1-12 configurations are engineered according to enclosure volume, electrical load profile and integration requirements. Agent selection is defined during technical assessment to ensure compatibility with safety and operational standards.

CO₂ (Where Applicable)

In specific enclosed technical compartments, CO₂ configurations may be applied where clean gaseous suppression is required and personnel exposure is controlled.

CO₂ suppresses fire by reducing oxygen concentration within the protected enclosure, interrupting the combustion process without leaving residue.

Technical characteristics:

CO₂ configurations are engineered case-by-case based on enclosure volume, accessibility and safety requirements. Application is defined during the engineering assessment to ensure compliance with operational and personnel safety considerations.

Compact Installation
