Fuses are essential components for circuit protection. They are designed to protect components from overcurrent such as shorts, overloads, accidental reverse polarity connections, incorrect voltage application and few other hazard situations. Fuses also protect the cables and wiring from overloads or shorts. The GDB-250MA fuse is one of the popular fuses used for various applications. This article provides information about the application field and working principle of the GDB-250MA.

The GDB-250MA is a 250mA, 32VDC, glass encapsulated fuse. It has an axial lead and is ideal for automotive, traffic control system, heavy load switches, medical equipment, power supplies/converters and telecom systems. It is a fast-acting fuse and can withstand surge currents ranging from 125 to 300A. The typical time-current characteristics of the GDB-250MA are as follows - at 250mA it has a hold time of 24 hours and a melting time of 0.2 seconds. At 375mA it has a hold time of 0,2 seconds and a melting time of 0.3 seconds. The GDB-250MA has a breaking capacity of 28A at 32V.

The GDB-250MA is designed to work with high surge currents and overvoltage with a high interrupting capacity. It can handle up to 300A of surge current and a breakdown voltage of 32V. It is designed to protect against short circuits, overloads, accidental reverse polarity connections and incorrect voltage application. The GDB-250MA has a current limiting characteristic which limits the peak current. It also has a resettable feature which allows it to reset itself once the current is gone. The fuse reset mechanism of the GDB-250MA is based on a thermal element. Once the thermal element is heated by the current, the fuse is triggered and an interruption occurs. Once the current is reduced, the thermal element cools down and the fuse is reset to its previous state.

The resettable behavior of the GDB-250MA makes it an ideal choice for applications where a reset capability is required. The fuse is also designed to withstand shock and vibration, providing excellent reliability. The fuse has a low power consumption which increases its efficiency and enhances its performance. The fuse also has a low failure rate and is capable of operating in extreme temperatures.

The GDB-250MA is widely used in automotive, industrial and commercial applications. It is ideal for use in harsh environments where shock and vibration is present. The fuse is also suitable for medium voltage applications, providing excellent over current and overload protection. The GDB-250MA is a reliable and efficient fuse for various applications and provides excellent heat dissipation and current limiting features.

In conclusion, the GDB_250MA is a reliable and efficient fuse for various automotive, industrial and commercial applications. It is designed to work with high surge currents and overvoltage with high interrupting capacity and features a resettable mechanism. The fuse can also operate in extreme temperatures and is designed to withstand shock and vibration. The GDB-250MA is an ideal choice for applications requiring reset capability and it provides excellent over current and overload protection.
