Mersen A6D2R Time-delay Fuse 600V RK1 2A 10-pack

Product Description

The MERSEN A6D2R is a Class RK1 time-delay fuse rated for 600 volts and 2 amps, sold in a 10-pack. RK1 fuses provide a higher level of current-limiting protection compared to standard Class K fuses, making them a common choice in industrial and commercial electrical systems. The time-delay characteristic allows the fuse to tolerate brief inrush currents from motors and transformers without nuisance blowing, while still providing reliable overcurrent and short-circuit protection. Licensed electricians install this fuse type in disconnect switches, motor control circuits, and panelboards where RK1-class protection is specified.

The A6D2R is suited for use in commercial and light industrial electrical installations where Class RK1 rejection-style fuses are required by design or code. The 600-volt rating covers single-phase and three-phase distribution circuits common in HVAC equipment, pump controls, and motor branch circuits. This 10-pack format supports stocking needs for service contractors and electrical maintenance teams who regularly replace fuses during scheduled maintenance or emergency service calls.

Key Features

• Class RK1 current-limiting design for enhanced short-circuit protection
• Time-delay characteristic tolerates motor and transformer inrush without nuisance blowing
• 600-volt rating covers single-phase and three-phase distribution applications
• 2-amp rating suitable for low-current motor branch and control circuits
• Sold in a 10-pack for efficient stocking and service use

Compatibility

Designed as an OEM-style replacement for Class RK1 time-delay fuses in 600-volt-rated fusible disconnect switches and motor branch circuit applications requiring RK1-class protection.

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 replacement fuse matches the voltage rating, ampere rating, and class of the original fuse before installation. Do not substitute a Class RK5 or lower-classification fuse in applications that specify Class RK1.
