CR2LS-50G/UL is a UL-recognized super rapid fuse designed for semiconductor and circuit protection in inverters and transformer-rectifier applications. It features a rated current of 50A at 250V AC with a maximum peak arc voltage of 500V and a maximum interrupting I²t of 0.85 Amp²×sec. × 10³. The fuse incorporates a blown indication fuse (G-type) that provides visual confirmation of fuse operation, and it has a watt loss of 6.0W during normal operation. With an interrupting capacity of 100 kA at 250V AC, this fuse provides rapid protection against abnormal currents and short-circuit faults while minimizing damage to related electrical equipment through its low arc voltage characteristics. The product is certified by UL (File No. E92312) and CSA (File No. LO4000-4090), making it suitable for industrial and commercial applications requiring reliable overcurrent protection.
