DAB7-125 27mm Miniature Circuit Breaker (MCB) 10KA/15KA: Robust and reliable, engineered for high-performance electrical distribution systems.
Introduction
Perfectly tailored for industrial and commercial applications, ensuring unparalleled safety and efficiency.
Electrical distribution needs are continuously evolving across residential, commercial, and industrial sectors. With an increasing emphasis on improved operational safety, continuity of service, greater convenience, and reduced operating costs, Miniature Circuit Breakers have been meticulously designed to meet and surpass these dynamic requirements.
Advantages
- Trip-free mechanism: Guarantees reliable protection by preventing the breaker from being held in the ON position during a fault.
- High breaker capacity: 15KA, designed to handle significant overloads and ensure robust system protection.
- Positive contact indication: Provides clear and immediate identification of contact status to assure maintenance safety.
- Dual protection with thermal and magnetic trip functions: Ensures comprehensive safeguarding against a wide range of electrical faults.
- Current limiting design: Delivers enhanced short circuit fault protection by restricting fault currents and limiting damage.
- Compliance and certification: CE marking and Semko product certification, ensuring adherence to international standards.
- Specification: Adheres to IEC 60947-2 standard, guaranteeing top-tier performance and safety.
