Main Features and Advantages
Unmatched protection for semiconductors: The Eaton Bussmann 170M5715 features a high-speed, current-limiting design that is essential for protecting power semiconductors. Its extremely fast clearing time and low arc voltage prevent the destructive thermal and mechanical stresses that can instantly damage sensitive components like diodes, thyristors, and IGBTs. By effectively limiting let-through current, the Eaton Bussmann 170M5715 ensures the longevity and reliability of your drive and power conversion systems.
Superior power dissipation and efficiency: With a power loss of only 110W, the Eaton Bussmann 170M5715 is engineered for high efficiency . This low watt loss translates to reduced energy consumption and heat generation within the electrical enclosure, contributing to lower operating costs and improved overall system performance. The unique square body geometry and high-quality materials used by Bussmann ensure excellent heat dissipation, allowing the Eaton Bussmann 170M5715 to operate reliably even under high ambient temperatures.
Robust construction and global compliance: Built to the highest industry standards, the Eaton Bussmann 170M5715 is a robust and durable component. It holds both IEC ratings and UL recognition, ensuring it meets the rigorous electrical safety requirements for global markets . The non-indicating design simplifies system design where a separate fuse monitoring system is used. The 115mm fixing centre configuration conforms to the US-style standard, making the Eaton Bussmann 170M5715 a direct and reliable replacement or upgrade for existing semiconductor protection applications.
