Electrical Fire Suppression Systems
Compact, rapid-response micro-environment protection engineered specifically for electrical switchboards, control panels, PCB components, and critical server enclosures.
- 3M™ NOVEC 1230 Agent: Non-conductive, clean, zero residue fire extinguishing gas.
- Automatic Thermal Actuation: Pre-calibrated glass bulb ampoules trigger at 68°C to 141°C.
- Integrated Electrical Cut-off: E-Bulb options immediately interrupt power to eliminate reignition risk.
- Autonomous 24/7 Protection: Operates independently without external power supplies or batteries.
Specialized Suppression Technologies
Our dual-tier electrical protection line covers everything from cabinet-wide enclosures to direct micro-component board protection.
AMFSS (Automatic Miniature Fire Suppression System)
The AMFSS range offers a compact, bolt-in direct or indirect response solution. Designed for internal switchboard cabinets, it discharges instantly upon thermal trigger, converting liquid suppressant to gas to isolate oxygen and cool the enclosure.
Fire Suppression E-Bulb
The E-Bulb is an ultra-compact fire suppression thermo-bulb mounted directly on electronic circuit boards or inside tight appliances. Filled with 3M™ NOVEC 1230, it stops electrical fires at the origin point while safely severing the circuit.
How AMFSS Suppression Works
4-Stage Instantaneous Automatic Thermal Suppression Mechanism
Thermal Detection
An abnormal temperature spike inside the electrical panel causes the calibrated glass bulb (ampoule) to rupture.
Plunger Actuation
The spring-tensioned internal plunger immediately pierces the cylinder disc, releasing the suppression fluid.
Head Assembly Distribution
Suppressant flows through the high-pressure cylinder opening into the precision brass discharge head assembly.
Gaseous Fire Knockdown
Agent exits via pre-drilled orifices, expanding into clean gas to extinguish flame through rapid cooling and oxygen displacement.
Applications & Protected Equipment
Engineered for high-risk electrical micro-environments across commercial, medical, and industrial sectors.
Installation Examples
