The GDA3 250V 3AMP Time Delay Fuse is designed for reliable performance in various applications. This fuse provides a delayed response to overcurrent situations, offering protection for sensitive equipment. With a voltage rating of 250V and a 3AMP capacity, it ensures durability and safety in demanding environments. Ideal for use in both residential and commercial settings.
A time-delay (slow-blow) fuse like the GDA3 is designed to tolerate brief, harmless inrush currents — such as those produced when motors, transformers, or capacitive loads start up — without blowing. It only opens the circuit when an overcurrent condition is sustained, protecting sensitive downstream equipment from nuisance interruptions while still providing reliable fault protection.
Generally, no. Substituting a fast-blow fuse in a circuit designed for a time-delay fuse can cause nuisance blowing on normal inrush currents, potentially damaging equipment or causing repeated downtime. Always replace a GDA3 with a like-for-like time-delay 5×20 mm fuse of the same amperage and voltage rating unless the equipment manufacturer specifically permits otherwise.
The GDA series fuse is a globally standardized IEC format and Northern Breaker Group regularly stocks or can source time-delay 5×20 mm fuses including the GDA3. If you need a cross-reference, a compatible equivalent, or a larger quantity, contact our Calgary, Edmonton, or Vancouver counters — or request a quote online — and our specialists will get you taken care of.
