Description

When selecting a circuit breaker for your industrial or commercial applications, it's crucial to consider the technical specifications that align with your operational needs. This particular circuit breaker offers robust features designed to ensure safety and reliability in demanding environments. Rated for a current of 20 A, this device is suitable for medium-load applications. It operates efficiently within a voltage range of 400/690 VAC, making it versatile for various electrical systems. The rated impulse withstand voltage stands at an impressive 8 kV, providing strong protection against transient overvoltages. With a breaking capacity of 4 kA and short circuit capacity reaching up to 25 kA, this breaker is engineered to handle unexpected surges effectively. Its electrical durability is rated at 10,000 cycles, ensuring long-term performance and reducing maintenance frequency. The unit adheres to high standards as evidenced by its compliance with IEC/EN 60947-2, IEC/EN 60898-1, and UL 1077 certifications. These approvals confirm its suitability for both local and international markets. Designed with practicality in mind, the breaker features a screw clamp terminal type requiring a tightening torque of 3.5 N-m. This ensures secure connections under varying conditions. The device's dimensions are compact yet substantial—54 mm in width, 95 mm in height, and a depth of 82.5 mm—allowing it to fit snugly into standard enclosures while maintaining accessibility. Safety is further enhanced by its IP20 degree of protection which safeguards against solid objects larger than 12 mm but does not provide water resistance; therefore installation should be considered accordingly based on environmental exposure. The Curve Type K characteristic allows it to handle slightly inductive loads without nuisance tripping—a valuable trait when dealing with motors or transformers that have higher initial currents upon startup. Temperature resilience is another highlight; operating smoothly between -25°C and +60°C while storage temperatures can range from -40°C to +70°C without compromising integrity or performance. Finished in RAL 7035 Grey housing color gives it a neutral appearance suitable for any professional setting without drawing unnecessary attention away from other equipment components within the system layout. Overall this circuit breaker represents an excellent balance between functionality durability compliance flexibility across multiple applications especially where consistent reliable power management solutions are required ensuring peace of mind through rigorous testing adherence industry standards Manufacturer Part Number not applicable here due duplication context elsewhere
