Description
Product name: WBK-3 Thermal Release Device Fire Shutter Price in Bangladesh
Product Overview
The WBK-3 Electric Thermal Release Device is a heat-activated drop unit for fire-rated shutter systems. It combines a thermal glass bulb with an integrated electrical signal cable. As a result, one device handles both the mechanical release and the electronic status signal.
When the red thermal bulb reaches its rated temperature, it releases the spring mechanism through a cable-pull action. Moreover, it sends an electrical signal to the fire alarm panel or control board at the same time. This makes it a good fit for modern fire shutter systems that need both release and monitoring.
Key Features
- Heat-activated thermal glass bulb
- Integrated electrical microswitch for status feedback
- Automatic release at the rated temperature
- Cable-pull mechanical drop action
- Heavy-duty steel construction
- Suitable for single-phase and three-phase fire shutter motors
- Universal mounting plate included
- Signal output to fire alarm panel or control board

Applications
Use the WBK-3 on fire roller shutter motors, smoke and fire curtain systems, and emergency drop mechanisms. It also works with fire and smoke dampers and feeds status back to fire alarm control units. It is commonly used with Chinese, Asian and European fire-rated shutter systems, including Jie Long shutter motors and generic fire shutter motor assemblies. However, confirm the bulb temperature rating and the microswitch wiring against your shutter motor and control panel before you install.
Conclusion
The WBK-3 gives a fire shutter system a thermal release and a signal output in one steel unit. Its glass bulb activation, pull-cable drop action and universal mounting plate make installation and replacement simple. Therefore, it suits fire-rated shutter projects that need both mechanical release and alarm panel feedback.
