ECSR35 is a Class RK5 dual-element, time-delay fuse designed to provide motor overload, ground fault, and short-circuit protection in circuits rated up to 600Vac. The fuse features a 10-second minimum time-delay at 500% rated current and a current-limiting design with an interrupting rating of 200kA RMS symmetrical, enabling it to be sized close to full-load amperage for maximum overcurrent protection. With dimensions of 5.5 inches (±0.31) in length and 1.06 inches (±0.008) in diameter, the ECSR35 is suitable for circuits subject to temporary motor overloads and surge currents from inductive components such as motors and transformers. This fuse simplifies system design by permitting the use of smaller and less costly switches and panels while providing superior short-circuit protection and selective coordination capabilities.
