Mersen GDG315/1000 Time Delay Fuse 250V 5-pack

Product Description

The MERSEN GDG315/1000 is a time delay fuse rated at 250 volts and 15/1000 amperes, designed to protect sensitive electrical circuits from sustained overloads and short-circuit events. This fuse provides the brief inrush tolerance required in low-amperage control and instrumentation circuits while still interrupting fault currents reliably. Each pack contains 5 fuses. The compact form factor measures 1.25 inches in length and 0.25 inches in diameter, fitting standard subminiature fuse holders found in control panels, HVAC equipment, and instrumentation enclosures. Licensed electricians and HVAC technicians are the primary installers.

The GDG315/1000 is suited for use in low-current control circuits across light commercial and residential HVAC systems, electronic instrumentation, and control board protection applications. The time delay characteristic allows momentary inrush currents to pass without nuisance tripping, making it appropriate for circuits with small motor loads or capacitive startup draws. It is sold in a 5-per-pack configuration for service technicians who replace these fuses as part of routine board-level diagnostics or control panel maintenance.

Key Features

• Time delay action tolerates brief inrush without nuisance tripping
• 250-volt rating suitable for standard single-phase control circuits
• 15/1000 amp rating for low-current instrumentation and control board protection
• Compact body: 1.25 inches long, 0.25 inches in diameter
• Sold in a 5-per-pack quantity for efficient service stock
• Lightweight at 0.01 pounds per fuse for easy handling in tight enclosures

Compatibility

Designed as an OEM-style replacement for subminiature time delay fuses used in low-current control circuits and electrical instrumentation panels rated up to 250 volts.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with applicable NEC guidelines. Always de-energize and lock out the circuit before removing or installing fuses. Verify the replacement fuse matches the voltage rating, amperage rating, and time delay class of the original before installation. Do not substitute a faster-acting fuse type, as this may cause nuisance tripping on circuits with inrush current.
