Features & benefits

• gLB ultra‑fast characteristic engineered for reliable semiconductor protection in DC circuits.
• High DC interrupting capability and low I²t characteristics (refer to datasheet for time‑current curves and coordination).
• Striker indication enables prompt blown‑fuse detection and optional microswitch integration.
• Silver‑plated copper terminals ensure low contact resistance; ceramic body provides thermal stability.
• Compact 14x51 format suitable for space‑constrained power assemblies.

Applications

• Protection of DC power converters, rectifiers, inverters, UPS, traction and industrial drives using power semiconductors.
• Use where high DC voltage interruption and rapid clearing of faults are required.

Installation & handling notes

• Replace only with identical Protistor® 14x51 gLB fuses to preserve protective coordination.
• Install in compatible clip mounting holders rated for gLB semiconductor fuses and ferrule terminals.
• Follow Mersen datasheet for mounting torque, conductor sizing and striker/microswitch wiring.
• Coordinate with upstream protective devices and verify equipment short‑circuit ratings.

Documentation & support

• Consult Mersen Protistor technical datasheets and time‑current curves for detailed selection, coordination and installation guidance.
