Motors draw extra current at startup, transformers can produce significant inrush current when energized, and electrical distribution equipment needs your dependable protection against overloads and short circuits. The Mersen TR250R 250 Amp Class RK5 Time-Delay Fuse is designed to meet these challenges in compatible industrial and commercial electrical systems. Part of Mersen's trusted Tri-Onic® TR-R series, this current-limiting fuse combines a 250A current rating, 250VAC and 250VDC voltage ratings, and time-delay performance in a blade-style configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e250-Amp Current
