Description
Fuse, 50 A, Dual, Class RK5, Ferrule End, 600 V, 20 kAIC at 250 Vdc
Features
- Engineered with a minimum 10-second time-delay at 500% load, this 50-Amp fuse easily absorbs the harmless, momentary inrush currents produced by heavy industrial motors, transformers, and HVAC systems. By distinguishing between normal starting surges and genuine overcurrent faults, it eliminates costly, frustrating system downtime while maintaining strict, uninterrupted branch circuit protection.
- Engineered with standard Class RK5 physical dimensions, this 50-amp fuse features a distinct rejecting slot in its brass end caps to prevent the accidental installation of lower-rated or non-current-limiting fuses. This physical barrier ensures your power distribution blocks, safety switches, and motor control centers maintain code-compliant, high-tier overcurrent protection.
- Boasting a versatile heavy-duty rating of 600V AC and 250V DC, this fuse is purpose-built to protect diverse power infrastructures. It handles everything from standard three-phase commercial HVAC equipment to industrial battery storage banks and solar photovoltaic combiners, simplifying your warehouse inventory by standardizing on a single, highly flexible part number.
- With a massive 200kA AC interrupting rating, this current-limiting fuse safely contains and extinguishes high-energy electrical faults before they can destroy downstream components. The rapid-response element opens quickly under short-circuit conditions, dramatically reducing harmful thermal and magnetic stresses within your electrical panels.
