Din Rail Series Hot Aerosol Fire Extinguishing Device
DIN Rail Fire Suppression — Direct Panel Integration, Zero Power Required
The EXFP7 Din Rail product is a thermal sensing aerosol fire extinguisher that directly mounts and installs on a TH35-7.5 DIN rail in a distributing board and control panel. There are two chemical weights — 10g and 15g — that provide coverage for 0.1m³ and 0.15m³ spaces and have super slim dimensions of 9mm, allowing it to sit among circuit breakers and contactors.

Product Information
Key Features & Typical Use
DIN Rail Integration — Direct Panel Installation
The EXFP7 Din Rail Series includes a specialized mounting clip that fits with standard TH35-7.5 DIN rails. So, no need for extra brackets, screws, or modifying panels to install.
Ultra-Slim 9mm Profile — Space-Saving Design
Din Rail Series has a minimal thickness of just 9mm, allowing it to take the same footprint as a miniature circuit breaker.
Thermal Sensing — Automatic Activation at 170±10℃
A thermal sensor line activates the device automatically at an enclosure temperature of 170±10℃. It doesn’t need any external power, control panel, or human intervention.
Multi-Hazard Coverage — Class A, B, C & E Fires
Designed for Class A, B, C, and E fires, a single device that can be mounted on a DIN rail is capable of providing total protection for a distribution enclosure.
EXFP7 Din Rail Series — Panel-Mount Aerosol Fire Extinguisher for Distribution Boards
The Din Rail Series is an aerosol fire extinguisher designed for installation in electrical distribution boards and industrial control panels. The device uses a solid aerosol-forming chemical with strontium nitrate and potassium nitrate as the active oxidizers to produce aerosol to suppress fire when heated above 170±10ΔC and does not cause damage to electronic components due to formation of residues. The Din Rail Series comes in two weight types: 10g and 15g covering the protected compartments of 0.1m³ and 0.15m³, which makes it fit for standard distribution cabinets. The device can be mounted on TH35-7.5 DIN rail without taking valuable installation space that can be utilized for other switches. Each device is tested in factories and sold with required documentation.
As a factory-direct manufacturer of safety devices we offer competitive prices and customized versions of fire safety devices.

Factory-Direct OEM / ODM Manufacturer
We Manufacture, You Brand
CE certified aerosol extinguishers · 10 years of assistance·
We provide the EXFP7 Din Rail Series manufactured in our own aerosol extinguishing devices factory to companies of the electrical sector worldwide. Your electric products can benefit from the din rail mounted aerosol extinguishers as they will allow for placing the fire protection in the panel without making panel layouts or redesigning it. Given a slim size of only 9mm the machine occupies the space of one single MCB, which is why it is very suitable for projects where every millimeter of rail space matters.

Frequently Asked Questions
What makes the EXFP7 Din Rail Series different from other aerosol extinguishers?
EXFP7 Din Rail Series is designed for direct snap-on DG-35-7.5 DIN rail mounting in electrical distribution, consumer units and control panels. Traditional fire extinguishers needed brackets and screws for mounting, but Din Rail Series seamlessly fits in beside circuit breakers, MCBs, RCDs, contactors, using only 9mm rail width at a time. This installation saves installation time and makes fire protection a part of electrical design.
How do I choose between the 10g and 15g models?
Selection depends on the internal volume of the distribution board or control panel. The EXFP7 Din Rail Series has an extinguishing density of 100g/m³. For the usual consumer units and small distribution boards (with internal volume up to 0.1m³), go with the 10g model (EXFP1/EXFP3/EXFP7 D0.01G/S-QR). For bigger panels, meter cabinets, and industrial eclosures (up to 0.15m³), go with the 15g version (EXFP1/EXFP3/EXFP7 D0.015G/S-QR). In both cases, the 9mm DIN rail footprint is constant which means the same layout can be used regardless of what the system’s capacity is.
What fire classes does the EXFP7 Din Rail Series cover?
The EXFP7 Din Rail Series has been approved for Class A (ordinary combustibles such as wood, paper and textiles) range of use, Class B (flamelike liquids such as fuels, oils and solvents), and Class C (flammable gases such as methane). This application of the Din Rail enables it to be widely used in distribution boards, consumer units and electrical cabinets, including in situations of fires from solid, liquid and electrical fire situations.
What is the service life and maintenance requirement for the Din Rail Series?
The EXFP7 Din Rail Series has a 10-year lifespan when used in typical environments at a temperature that ranges from -50°C to +90°C and a humidity of ≤95% RH. It does not require any maintenance at all during this time because it does not have any pressurized containers which need to be routinely checked, nor does it require charging of any chemical component nor cleaning of any filters nor replacing moving parts. We recommend a casual inspection of the thermal sensing line and case every 2-3 years.
Can the Din Rail Series be installed alongside other DIN rail components?
The EXFP7 Din Rail series is built with standard DIN rail products in mind and has an ultra slim 9mm profile which utilizes the same panel space as one MCB pole. This allows installation alongside circuit breakers, RCDs, contactors, terminal blocks, surge protectors and PLCs without additional need for panel space. The snap-on mounting clip permits easy installation and removal, thus making retrofitting into existing distribution networks easier.
What are the typical applications for the EXFP7 Din Rail Series?
The EXFP7 Din Rail Series is suitable for consumer units, distribution boards, control panels, meter cabinets, telecom power panels, renewable energy boxes, EV chargers, and building automation panels. The DIN rail is useful in applications in which there is little space and integrated fire protection is necessary and standard electrical components are used. The extreme temperatures (-50℃ to +90℃) and 10-year life make this product appropriate for outdoor or remote locations where maintenance is denied.
