Industrial ECSR150 Bullet Style Fuse 150 Amp 600V Fast Acting

The ECSR150 bullet-style fuse is a 150 A, 600 VAC time-delay current-limiting device from Edison (Eaton’s Bussmann family), designed for feeder and branch protection in industrial power systems. It features dual-element RK5 protection with blade-end terminals on both ends, a non-indicating body, and a 200,000 AIC interrupt rating, with UL and CSA approvals for 600 VAC service. The fuse measures about 1.61 in in diameter by 9.63 in long (40.9 x 244.6 mm) and is intended for inline mounting in equipment and distribution panels that require reliable protection against short-duration overloads. It tolerates temporary overloads up to 500% of rated current for up to 10 seconds, making it suitable for applications such as feeders and motor-load protection where brief surges may occur.
