Industrial CSR200 Time Delay Dual Element Fuse

CSR200 (ECSR200) is a 200 A, 600 V class RK5 dual-element time-delay fuse designed for branch and feeder protection in AC power systems, including mains feeders, panel boards and switchgear, AC drives, and load centers. It uses blade-end terminals and a fiberglass cartridge body, delivering current-limiting protection with a 10-second time delay at 500% rated load to accommodate startup surges in motors and transformers. The unit measures approximately 9.63 inches long and 1.61 inches in diameter, and provides a 200 kA RMS symmetrical interrupting rating on the AC side; UL and CSA approvals accompany 600 V operation, making it suitable for industrial protection tasks in control panels and feeders.
