Description

The ICS Triplex T9901 is a certified replacement input fuse designed for use with specific Trusted TMR analog and digital input modules, including the T9801, T9802, T9803, T9831, T9832, and T9833 series. This fuse ensures overcurrent protection while maintaining system availability in safety-critical applications.

Each T9901 unit is a 50 mA, 125 V DC time-delay (slow-blow) fuse that tolerates brief inrush currents without nuisance tripping. This characteristic is essential for reliable operation during power-up or transient events in industrial control environments.

Although listed in ICS Triplex documentation as a proprietary part, the T9901 fuse conforms to UL 248-14 standards and features lead-free construction, aligning with RoHS compliance requirements. The fuse is typically supplied in factory-sealed packs of 20 units, supporting efficient spare parts management.
