Mersen 6K60R Class RK1 Fast-acting Fuse 60A 600V

Product Description

The MERSEN 6K60R is a Class RK1 fast-acting current-limiting fuse rated for 60 amps at 600 volts AC and 300 volts DC. Part of the Amp-Trap A6K-R series, this ferrule-style fuse is engineered to provide reliable overcurrent protection in circuits where high available short-circuit currents are present. With an AC interrupting rating of 200 kA, it delivers robust fault-current limiting performance. The PolyTube body construction and tin-plated copper ferrule terminals make this a durable, field-ready component for licensed electricians working on branch and feeder circuit protection applications.

The 6K60R is suited for branch circuit and feeder circuit installations in both AC and DC systems operating at 50 or 60 Hz. Its fast-acting characteristic makes it particularly effective as back-up protection in commercial and industrial panels where high fault-current exposure demands a Class RK1 rated device. The clip-mount ferrule design fits standard fuse holders and disconnect blocks sized for this class and ampere rating.

Key Features

• Class RK1 current-limiting rating for superior fault protection
• Fast-acting response suited for branch and feeder circuit back-up protection
• 200 kA AC interrupting rating for high available fault-current environments
• Dual-rated for AC and DC service: 600 volts AC and 300 volts DC
• Tin-plated copper ferrule terminals resist corrosion and ensure low-resistance contact
• PolyTube body construction for durable insulation in demanding installations

Compatibility

Designed as a Class RK1 ferrule-style replacement fuse for standard clip-mount fuse holders and disconnect blocks rated for 60A at 600 volts AC.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before removing or installing fuses. Verify that the fuse holder or disconnect block is rated for Class RK1 ferrule fuses at the required voltage and ampere rating before installation. Never replace a blown fuse without first identifying and correcting the cause of the overcurrent condition.
