GQRR-L0.01G Aerosol Fire Extinguishing Device 10~50L

caiyijie — Tue, 30 Dec 2025 06:07:21 +0000

GEYA GQRR-L0 Advanced Fire Protection for Critical Assets

The GQRR-L0.01G Aerosol Fire Extinguishing Device represents the cutting edge in miniature fire suppression technology. Designed exclusively for the UAE market, this device offers a robust solution for protecting small enclosed spaces such as electrical distribution boards, vehicle engine compartments, and server racks.

Unlike traditional extinguishers, this unit uses a solid-state Strontium Nitrate-based compound that transforms into a rapidly expanding aerosol upon activation, flooding the protected zone and neutralizing the fire chemically.

Lead wire length: 10cm(default), 20cm, 30cm, 50cm

Lead wire quantity: 2:2 wire(default), 1:1 wire

Scientific Fire Suppression Mechanism

The core agent utilizes Strontium Nitrate (Sr(NO₃)₂) (Content: 50%~58%). Upon thermal activation via the fuse, a chemical reaction occurs:

2Sr(NO₃)₂ → 2SrO + 4NO₂↑ + O₂↑

This process extinguishes fire through three main pathways:

Chemical Inhibition: The Strontium Oxide (SrO) particles interrupt the chain reaction of combustion radicals.
Suffocation: Inert gases released dilute the oxygen concentration around the flame just enough to stop burning.
Cooling: The endothermic decomposition absorbs heat from the fire source.

Note: Chemical inhibition and suffocation are the primary extinguishing methods.

Installation & Safety Features

Versatile Mounting

The device supports both Standard Rail Mounting and high-strength 3M Adhesive application, allowing for secure placement in any orientation.

Safety Warning

This UAE-specific model includes prominent warning markings on the side profile. The PA66 outer shell is durable and heat resistant.

Packaging Information

Quantity per Carton 100 Units
Weight per Carton 5.5kg / carton (10g model) 6.5kg / carton (20g model)

GYR9NE 1P+N Electronic RCBO

caiyijie — Thu, 25 Dec 2025 09:06:43 +0000

GYR9NE: Precision Electronic Protection for Modern Circuits

The GYR9NE 1P+N Electronic RCBO is the voltage-dependent version of our popular residual current circuit breaker series. By utilizing advanced electronic amplification technology, the GYR9NE provides a highly sensitive and economical solution for protecting personnel and equipment against electric shock and fire hazards.

Designed primarily for residential and standard commercial applications, this device integrates the functions of an MCB (Miniature Circuit Breaker) and an RCD (Residual Current Device) into a compact unit, saving valuable space in distribution boards.

Key Features & Benefits

1. Electronic Operation Mechanism

Unlike electromagnetic types, the GYR9NE uses an electronic amplifier board to detect residual currents. This technology allows for:

High Sensitivity: Rapid detection of leakage currents (30mA, 100mA, 300mA options).
Compact Design: Easier to manufacture in smaller form factors.
Cost Efficiency: A more affordable solution for general-purpose applications, covering over 90% of household needs.

2. Comprehensive Safety Assurance

The GYR9NE ensures complete peace of mind by monitoring for three distinct types of electrical faults:

Earth Leakage: Disconnects power immediately if a person touches a live wire or if insulation fails.
Overload: Prevents cable overheating when too many appliances are active.
Short Circuit: Instantly breaks the circuit (up to 6kA) during major electrical faults.

3. User-Friendly Design

The unit features a Leakage Fault Indication window, allowing users to quickly identify if a trip was caused by an earth fault or an overload. It supports a wide range of wiring capacities (1-25mm²), making it compatible with various installation requirements.

Electronic vs. Electromagnetic: Which should you choose?

The GYR9NE (Electronic) relies on line voltage to operate. It is the market standard for stable grid environments like homes and offices due to its high value-to-performance ratio.
Note: If you require a breaker that operates independently of line voltage (for environments with frequent voltage fluctuations or neutral line loss), please view our GYR9NM Electromagnetic RCBO.
