Edison JM60400-1CR Eaton Bussmann series JM modular fuse block, 600V, 225-400A, Knife Blade End X Knife Blade End, Single-pole

Description

Features

• Featuring a versatile, single-pole modular footprint, the JM60400-1CR allows for easy gang-mounting to create multi-pole configurations. This flexibility enables industrial engineers to optimize panel space and customize layouts for specific motor control centers or transformer protection without the need for multiple, bulky SKU inventories.
• Specifically engineered to house 225A to 400A Class J fuses, this holder offers a compact footprint with high interrupt ratings up to 200kA. By utilizing the space-saving dimensions of Class J fuses, you achieve maximum short-circuit current rating (SCCR) protection for sensitive downstream components while occupying significantly less enclosure volume than Class R or H alternatives.
• Equipped with high-conductivity Al/Cu box lug connectors, this holder accepts a wide range of wire sizes (typically up to 600kcmil) to accommodate heavy-duty industrial feeders. The robust terminal design ensures a low-resistance connection that minimizes heat generation, reducing the risk of thermal fatigue and ensuring long-term reliability in high-amperage power circuits.
• Constructed with reinforced thermoplastic and integrated safety barriers, the block provides high dielectric strength and physical isolation between phases. The open-front design facilitates rapid fuse replacement and allows for easy access during infrared thermography scans, helping maintenance teams identify potential hotspots before they lead to catastrophic equipment failure.
