Product description

The Mersen (formerly Ferraz Shawmut) TRS12R Tri-Onic is a premier Class RK5 time-delay fuse engineered specifically for motor circuit protection in demanding environments. This 12 Amp, 600V fuse utilizes advanced Tri-Onic technology to provide current-limiting protection that significantly reduces the let-through energy during short-circuit events. Its time-delay characteristics are finely tuned to withstand the initial inrush current of inductive loads, making it an ideal choice for protecting small motors, control transformers, and lighting ballasts. By effectively managing both sustained overloads and high-energy faults, the TRS12R ensures the longevity of electrical infrastructure and minimizes the risk of arc flash incidents. The rejection-style ferrule design ensures correct application within safety-rated fuse holders.

Product highlights

• Tri-Onic Protection: Advanced current-limiting technology minimizes the impact of short-circuit energy on equipment.
