1. Comprehensive Protection Functions
Simultaneous 2-Pole Disconnect: Features an internal common trip mechanism. If a fault occurs on one line, both poles trip instantly. This safely disconnects both Live and Neutral (or two phases) simultaneously, achieving complete electrical isolation for maintenance personnel.
Overload Protection: Equipped with precision bi-metallic strips that accurately detect sustained overcurrents, cutting the power before wire insulation degrades or appliances overheat.
Short Circuit Quick Break: Utilizes an advanced electromagnetic tripping system to instantly extinguish massive fault currents, effectively mitigating the risk of electrical panel fires.
2. Premium Material & Robust Structure
High-Quality Flame Retardant Shell: Constructed from industrial-grade, impact-resistant thermosetting materials (V0-grade). It ensures excellent thermal endurance and completely prevents combustion.
Universal DIN-Rail Mounting: Features a heavy-duty pull-down clip at the base for effortless snapping onto standard 35mm DIN rails, ensuring a vibration-resistant fit inside the distribution board.
High Conductivity Copper Parts: Internal electrical contacts and sturdy screw terminals are forged from high-purity copper, minimizing contact resistance and preventing dangerous heat build-up under full 20A loads.
3. Superior Performance Advantages
Reliable 6kA Breaking Capacity: Confidently interrupts standard fault currents up to 6000 Amps, making it the perfect and highly cost-effective choice for residential, commercial, and light-industrial applications.
Clear Visual Status Indication: The distinctive teal-green toggle switches clearly display the 'O OFF' status, allowing facility managers to verify complete circuit safety instantly.
Global Standard Compliance: Fully CE certified, ensuring seamless customs clearance and market acceptance across Europe, the Middle East, and Asia.
