What type of fuse allows for a time delay?
A time delay fuse is a special kind of fuse that allows electrical surge for a short time before it actually blows. Due to its special design, it can bear electricity overload in a repeated cycle for a short period without blowing….Your Branch:

What does time delay fuse mean?
The time-delay, or “slow blow”, fuses were developed for situations where acceptable momentary overloads are encountered, such as starting a motor. As the name implies, this type of fuse will carry an overload several times the normal load for a short period of time without blowing.
Do I need a time delay fuse?
Some electrical devices need a high inrush of current to start their function. These time-delay or slow-blow fuses can sustain overloads for a limited period. They are perfect for those electronics as they allow the initial surge of power without destroying the circuit.
What is time delay fuse and non time delay fuse?
A time delay fuse allows short pulses of current in excess of the rated current for the fuse. A non-time delay fuse is much less tolerant of overcurrent spikes. The purpose of this type of fuse is to allow a surge in electricity for a short time before the fuse actually blows.
How do I know if my dual element fuse is blown?
Remove the fuse from its holder. In some cases you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.
How long is a time delay fuse?
TIME –DELAY fuses will not blow unless an over- load condition exists for an extended period of time, typically 10 seconds. The time delay is usually required when a motor has high starting currents. The TIME-DELAY fuse has a disadvantage to the FAST-ACTING fuse if an extremely high current overload occurs.
How do I know if my white fuse is blown?
A homeowner can determine if a glass fuse in blown by performing a visual inspection and looking for a break in the thin wire and a brown discoloration in the center of the fuse. A ceramic fuse, however, shows no damage upon visual inspection. Testing a ceramic fuse is the only way to tell if the fuse has blown.
