FAQs
To install TPS-50LB, ensure the PCB tab and bolt tag terminals align with the board footprint or terminal block. Secure the PCB tab connection and tighten the bolt tag to manufacturer torque specs, while observing the 50 A rating. Since this is a non-indicating fuse, verify system status via panel indicators or a separate fault-monitoring device after installation.
TPS-50LB is rated for 50 A continuous current, 170 Vdc maximum voltage, and a 100 kAIC interrupt rating. These specifications provide reliable short-circuit protection for telecom power feeds and data-center circuits while supporting current-limiting protection in compact form factors.
Yes. The TPS-50LB is CE marked and RoHS compliant, supporting regulatory compliance in European markets and helping you meet supplier and environmental standards for electronics assemblies and telecom equipment.
Typical applications include telecom network gear, data-center communication racks, and panel-mounted power distributions where space is limited. Its PCB tab and bolt tag terminals enable flexible mounting in crowded enclosures, while its current-limiting protect-by-design features help safeguard sensitive data-path components.
TPS-50LB provides high fault-current tolerance with a robust glass-melamine tube and plated ferrules, reducing replacement frequency in harsh environments. Its compact, non-indicating design lowers panel real estate needs and simplifies wiring, contributing to lower maintenance costs and improved uptime for network infrastructure.
