Fuses are electrical components which are designed to protect other components and circuits by preventing excessive current from flowing. The MDQ-7-1/2 is a slow-blow fuse which is used in a variety of DC applications. It is mainly used in high-current, low-voltage DC circuits.

The MDQ-7-1/2 has a 7.5 Amp rating and is suitable for 600 Volts DC. It has a time-delay mechanism which allows a short duration of current above its rated value, without breaking the circuit. This feature makes it suitable for use in inrush current applications associated with motors, solenoids and transformers.

This type of fuse has a metal body with copper end caps. It is designed to be snap-fitted and is supplied with a metal mounting bracket that lets it easily fit into panels. The fuse should be placed in a holder designed for that purpose. The mounting bracket should be firmly screwed onto a clean panel surface, preferably after cleaning it with petroleum jelly.

The MDQ-7-1/2 fuses are designed to blow during a sustained overload or short circuit. This is done by an internal element that melts when it reaches the fuse’s rated current. This melts the link and breaks the circuit, preventing any further current from flowing.

The electrical characteristics of the MDQ-7-1/2 include a nominal 8 hours current rating of 7.5 Amp, a minimum clearing current of 10 Amp, and a DC/50V voltage drop. The MDQ-7-1/2 is designed for use in a wide range of DC applications such as actuator systems, direct current drives, digital signal processing, uninterruptible power supplies, and more.

The MDQ-7-1/2 is a reliable and cost-effective component that provides protection from overloads and short circuits. It is important to note that the fuse should not be used in circuits with voltage higher than its rating as it may cause an explosion, fire, or other dangerous situations.
