Changeover contact of indicator activation insert, AC 250V, 10/3A, for sizes 1, 2, 3 XNH123-XMFM 182998

Trip indicator for XNH fuses – reliable status indication

This alternating contact is a key signalling element for XNH series fuses, providing precise information about the operation of the insert. Designed to work with fuses of sizes 1, 2 and 3, it offers reliability and easy integration with monitoring systems. Designed for professional installations, but also useful for end users who need confidence in the operation of protection devices.

Functionality and application

The XNH123-XMFM contact is used to signal the operation of the fuse insert. Therefore, in the event of a failure or overload, the operator is immediately informed of the need for intervention. This signalling can be used to trigger alarms, shut down power to other devices, or simply for visual monitoring of the installation status. AC 250V voltage and 10/3A current guarantee compatibility with a wide range of control and automation systems.

• Trip indication: Immediate information about a blown fuse insert.
• Compatibility: Designed for XNH fuses sizes 1, 2 and 3.
• Versatility: Can be used in various monitoring and control systems.
• Durability: According to the manufacturer's information, it withstands short circuits up to 120kA (at 500V) or 100kA (at 690V). This ensures long-lasting and trouble-free operation even in difficult conditions.
• Flexible mounting: The possibility of connecting wires from the top or bottom facilitates installation in tight spaces.
• Safety: In combination with other Eaton accessories (e.g. touch protection), it ensures complete safety of use.

Technical characteristics and construction

The contact has been designed with reliability and durability in mind. The materials used and precise workmanship guarantee stable operation for a long time. The design allows mounting on a 60mm rail pitch, which is standard in most electrical installations. Additionally, a version with a blown indicator is available, which facilitates diagnostics and quick fault location. This is not only a signalling element – it is an integral part of the electrical installation safety system.
