Overview

The Littelfuse Up-LINK POWR-SAFE CC Holder (SKU: LINK003C) is a 3-pole, DIN rail-mounted solid-state fuse holder engineered for advanced remote fuse status indication and local LED monitoring. This cost-effective solution eliminates the need for proprietary network protocols, enabling seamless integration with existing PLCs or industrial control systems. The holder provides real-time fuse status updates, reducing unplanned downtime, minimizing production scrap, and enhancing worker safety by preventing unsafe conditions during fuse inspection or replacement. Designed for Class CC and midget-style (10 x 38 mm) fuses, the LINK003C delivers superior overcurrent protection with a 600V AC/DC voltage rating and 30A ampere capacity. Its high interrupting rating of 200kA (Class CC) ensures robust fault current handling, while the current-limiting fuse design enhances circuit protection. The ventilated housing promotes cooler operation, and the IP20 finger-safe construction meets IEC and UL Touch Safe standards for personnel protection during fuse changes. Installation is simplified with 35mm DIN rail mounting and tool-free fuse removal. The pressure plate terminal accepts wire ranges from #8 to #14 CU with a recommended torque of 17.7 in-lbs. Optional microswitches enable remote communication of fuse status to PLCs or monitoring systems, while local LED indicators provide immediate visual feedback. The holder is UL Listed, CSA Certified, and RoHS compliant, making it suitable for industrial applications including motors, control circuits, transformers, and photovoltaic systems. Compatible with Littelfuse ATDR, ATMR, and ATQR fuses for DC applications, the LINK003C supports modular expansion through field assembly of multi-pole configurations. Its compact footprint and dead-front design reduce installation space requirements while improving safety. For advanced monitoring, the optional microswitch accessory (sold separately) enables integration with existing automation systems to track fuse type, part number, and replacement location data.
