Electrical fires are one of the most common causes of damage inside distribution boards, switchgear panels, CNC controller boxes, and box MCB enclosures. Traditional fire extinguishers are effective, but they require manual operation. What happens if no one is present?

The CNC Electric Aerosol Fire Extinguisher DIN Rail type is a compact fire extinguisher specially designed for electrical panels and enclosed cabinets. It automatically detects and suppresses fire at the source without human intervention.

What is an Aerosol Fire Extinguisher?

An aerosol fire extinguisher is an automatic fire suppression device that releases ultra-fine potassium-based aerosol particles to interrupt the chemical chain reaction of fire.

Unlike a pressurized water fire extinguisher or portable extinguisher, this unit:

• Does not use water
• Does not damage electrical equipment
• Leaves minimal residue
• Works automatically inside enclosed spaces

It is ideal for:

• Distribution boards
• Switchgear cabinets
• CNC controller boxes
• Solar DB boxes
• Voltage protection relay panels
• Under voltage relay enclosures
• Manual changeover switch cabinets
• Power supply voltage switch rooms

Why Electrical Panels Need Dedicated Fire Protection

Electrical panels contain:

• MCBs
• MCCBs
• Relays
• Busbars
• Changeover switches
• Voltage protection relay systems
• High current connections

Overheating, loose wiring, short circuits, or overload can cause internal arc faults. A standard fire extinguiser placed outside the room will not react fast enough.

That’s why modern fire equipment safety standards recommend cabinet-level fire suppression.

Key Features of CNC Electric Aerosol Fire Extinguisher

 DIN Rail Mounting Design

The unit is specially designed for easy installation on DIN rail inside switchgear or distribution boxes.

 Automatic Activation

Heat-sensitive trigger activates automatically when temperature rises beyond the threshold. No manual switch required.

 Compact Fire Extinguisher Size

Slim body design makes it suitable for tight electrical cabinets where space is limited.

 Safe for Electrical Fires

Perfect electrical fire fire extinguisher solution:

• Non-conductive
• No water damage
• No short circuit risk

 Clean Agent Technology

The aerosol compound interrupts combustion without damaging:

• Box MCB
• Voltage relay
• Power supply voltage switch
• CNC controller box components

 Zero Pressure Cylinder

Unlike traditional fire-extinguisher cylinders, this system operates without high-pressure gas storage.

 Minimal Maintenance

Long operational life with reliable activation mechanism.

How Does It Work?

When temperature inside the cabinet increases:

1. Heat trigger activates
2. Aerosol compound releases
3. Fire chemical chain reaction is interrupted
4. Flames are suppressed instantly
5. Equipment remains protected

It stops fire at ignition stage before it spreads.

Where Can It Be Used?

This aerosol fire extinguisher is ideal for:

• Industrial switchgear panels
• Solar distribution boxes
• Data center cabinets
• CNC controller box systems
• Telecom cabinets
• Power distribution rooms
• Commercial electrical panels
• Under voltage relay protection panels

If you are planning to buy a fire extinguisher for panel-level protection, this is the most advanced solution available today.

Why Not Use a Traditional Portable Extinguisher?

Traditional fire extinguishers:

• Require human presence
• May cause water or powder damage
• Cannot suppress fire inside sealed cabinet
• Are reactive, not preventive

The CNC DIN Rail Aerosol Unit is proactive fire protection.

Fire Extinguisher Price in Pakistan – What to Consider?

When searching for fire extinguisher price in Pakistan, don’t just compare cost.

Consider:

• Type of fire (electrical vs general)
• Installation location
• Cabinet volume
• Automatic vs manual system
• Supplier reliability

CNC Electric is a trusted fire extinguisher supplier providing certified fire safety fire extinguisher systems for industrial use.

What is Used in Fire Extinguisher Technology?

Different extinguishers use different agents:

• Pressurized water fire extinguisher – for Class A fires
• CO₂ – for electrical equipment
• Dry powder – multi-purpose
• Aerosol compound – advanced electrical fire suppression

The CNC system uses a potassium-based aerosol compound designed specifically for electrical fire protection.

Why CNC Electric?

CNC Electric is known for:

• Box MCB protection systems
• Voltage protection relay devices
• Manual changeover switch solutions
• Under voltage relay technology
• Switchgear components
