0473001.MRT1

A 0473001 MRT1 fuse is an overhead, operated, fault-activated disconnecting fuse used in overhead distribution systems. It is designed to de-energize the electrical system in the event of a direct or indirect fault in the system, regardless of whether it is single-phase or three-phase. The fuse is also designed to re-energize the system after the fault has cleared. This type of fuse is designed for use in medium and low voltage overhead systems.

The 0473001 MRT1 fuse consists of a fuse link, an operating unit, a small spring-loaded contact, a hook-shaped conductor, and a contact plate. The fuse link is housed in the operating unit and is connected to the contact plate. The spring-loaded contact is connected to the hook-shaped conductor and the contact plate. The contact plate is connected to the main feeder line. The operating unit has a movable latch that is operated by a manual lever.

When the 0473001 MRT1 fuse is first installed, the fuse link is in a safe position and the contact plate is connected to the main feeder line. If the current in the main feeder line exceeds the rated ampacity of the fuse link, the fuse link will melt. This will cause the spring-loaded contact to separate from the contact plate and the latch to move to an open position. The result is that the main feeder line is de-energized.

After the fault is cleared, the fuse link must be replaced before the system can be re-energized. The operator will move the lever to the "off" position. This will cause the latch to move back to the closed position and the fuse link to reset. The contact plate will once again be connected to the main feeder line and the system will be re-energized.

The 0473001 MRT1 is ideal for use in overhead distribution systems that require fast-acting protection against faults. The fuse is reliable and easy to maintain, and can be used in a wide range of applications. It is also available in a wide range of sizes and current ratings, making it suitable for use in a variety of system configurations. This type of fuse is UL listed and is designed to meet or exceed the applicable UL and CSA standards.
