Overview

The Littelfuse MSXL2000C (SKU: MSXL2000C) is an external mount microswitch designed for permanent blown fuse indication with Littelfuse PSX Series High-Speed Square-Body Semiconductor Fuses. This accessory is compatible with PSX Series fuse case sizes 1XL, 2XL, and 3XL, offering a crucial visual alert system for critical electrical systems. The MSXL2000C features a dual-contact configuration, including one normally open (N.O.) and one normally closed (N.C.) contact, both rated for 4A at 250V AC. A prominent red flap or arm indicator visually signals a blown fuse condition. This indicator also functions as a manual reset mechanism for the microswitch contacts, allowing for straightforward system restoration after a fuse replacement. The internal microswitch component is UL Recognized (UL File: E176213), ensuring adherence to established safety and performance standards. Constructed with silver-nickel plated copper contacts and a housing rated UL 94 V0 for flammability, the MSXL2000C is built for durability and safety in industrial environments. It operates reliably within an ambient temperature range of -25 °C to +125 °C and is RoHS compliant. This microswitch is essential for applications utilizing PSX Series fuses where immediate blown fuse detection is paramount for maintaining operational integrity and preventing potential system damage. The external mount design simplifies installation and maintenance within electrical enclosures. The flexibility of the N.O. and N.C. contacts allows for diverse signaling and control strategies based on fuse status.
