Description

Industrial Fuse Monitoring Module (2 or 3 Phase Fail Alarm)

The Fuse Monitoring Module is a compact DIN rail-mounted fuse fail indicator designed to continuously monitor fuses in two-phase or three-phase systems. Engineered for reliability and simplicity, this module provides immediate visual and alarm indication when a fuse failure occurs, helping reduce downtime and improve system safety.

Operating from a low 5V DC supply, the unit features individual phase status LEDs and a power-on indicator for clear system visibility. In the event of a blown fuse, the corresponding red LED illuminates and an alarm output is activated. The alarm also triggers if the module itself loses power, ensuring users are alerted to both fuse and supply issues.

Available in 2-channel and 3-channel versions, this fuse monitoring module is ideal for industrial panels, HVAC systems, and three-phase power control assemblies where continuous fuse supervision is critical.
