Miniature 4P PA66 flame-retardant circuit breaker for commercial buildings, 400V AC 20A

Discover our miniature circuit breaker, an essential piece of equipment for the safety of your electrical installations. Its casing is made of PA66 material, offering excellent fire resistance for enhanced safety. It provides reliable protection against short circuits thanks to its electromagnetic tripping mechanism, which stably interrupts the current. Furthermore, its rapid arc extinguishing capability helps prevent fire hazards. Its installation is simplified by a double-clip locking structure, allowing for horizontal handling and easy mounting/dismounting even in confined spaces. Versatile, this circuit breaker is ideal for protecting electrical distribution systems in residential, commercial, and industrial environments. You will receive: 1 miniature circuit breaker. **Detailed Specifications:** **Item Type:** Miniature Circuit Breaker **Material:** PA66 **Rated Insulation Voltage (Ui):** 500V AC **Pollution Level:** 3 **Impulse Withstand Voltage (Uimp):** 6kV **Magnetic Tripping Curves:**
