FAQs
GMT-3-1/2A uses tin-plated beryllium copper terminals for reliable contact. To install, insert the fuse into compatible holders or fuse blocks designed for small-form telecommunication fuses, ensuring solid contact with clean, flat terminals. Verify the amperage and voltage ratings (3-1/2A, 125 VAC/60 VDC) match the protected circuit. Use proper torque and secure mounting to minimize vibration-related wear.
The GMT-3-1/2A is rated for 3-1/2 A with voltage ratings of 125 VAC and 60 VDC. It is designed for telecom and network equipment, including rack-mounted gear and data-center infrastructure. Its fast-acting characteristic delivers rapid fault clearance, reducing downstream damage and supporting tight coordination with upstream protection devices.
Yes, GMT-3-1/2A is well-suited for data center telecom protection and network equipment. It fits in standard fuse holders within telecom cabinets and rack panels, especially where a compact, non-indicating, fast-acting fuse is preferred for space-constrained layouts and where centralized monitoring is used instead of local indicators.
GMT-3-1/2A carries CE Marking and RoHS compliance, confirming adherence to European safety, health, and environmental standards. This helps with regulatory compliance for European installations and green procurement programs, reducing risk during audits and facilitating cross-border deployments in many telecom facilities.
ROI comes from reduced downtime due to fast-acting fault clearance, lower maintenance costs from improved contact reliability (tin-plated terminals), and simplified inventory with clear color coding. Its compact size also lowers cabinet redesign costs and supports scalable protection across multiple telecom devices and racks.
