Fuse 400 Amp 250VAC Dual-Element Time-Delay Fuse – Electrical Protection The Bussmann Fuse 400 Amp 250VAC Dual-Element Time-Delay Fuse is designed for advanced electrical protection in industrial and commercial applications. This Class RK5 fuse provides reliable motor overload, ground fault, and short-circuit protection, making it suitable for electrical distributors, lighting solutions, wire and cable systems, and switchgear suppliers requiring high-performance current-limiting fuses. Specifications Manufacturer: Bussmann Manufacturer Part #: FRN-R-400 Class: Class RK5 Voltage Rating: 250 VAC Amperage: 400 amperes Interrupting Rating: 200 kiloamps Connection Type: Blade End Type: Blade Dimensions (L x W x H): 8.63 in x 2.06 in x 2.06 in Product Weight: 1.0000 lb UPC: 051712507530 Features Dual-element, time-delay design provides protection against motor overloads and short circuits. Time-delay feature allows the fuse to withstand temporary motor overloads and surge currents for a minimum of 10 seconds at 500% of rated current. Current-limiting fuse reduces let-through energy to protect downstream equipment. Helps prevent motor burnout from overloads and single-phasing when properly sized. Simplifies blackout prevention through selective coordination. Downloads & Links Frn-R-400~Fusetron Dual-Element Class Rk5
