S505-2.5-R fuses, also known as dual element time-delay fuses, are designed for both over-voltage and short circuit protection. They are mainly used in industrial, commercial, residential and agricultural applications. This type of fuse is also suitable for use in aerial supply circuits, electric motors, transformers and fluorescent lamps. The fuse features a metal construction with a high breaking capacity, providing greater over-current protection than other types of fuses. The design of the fuse also ensures reliable operation in high ambient temperatures.

The S505-2.5-R fuse consists of two elements: the primary element and the secondary element. The primary element is a solid-state component which provides a preset over-voltage protection level. This element senses an over-current situation and then opens, thus removing the over-current condition. The secondary element is an inductive component which senses a short circuit situation and then opens, and removes the short circuit condition. This dual element design provides both over-voltage and short circuit protection to the circuit.

The operation of the S505-2.5-R fuse is relatively simple. It works by measuring the current across its terminals and then responding accordingly. If the current exceeds the preset protection level, the primary element will open, eliminating the over-voltage condition. If a short circuit is presented to the fuse, the secondary element will open, breaking the circuit.

The S505-2.5-R fuse can be used in a variety of different applications. It is commonly used as a primary protection device in residential, commercial, industrial and agricultural applications. Additionally, it can be used as a secondary device in aerial supply cables, electric motors, transformers and fluorescent lamps. Furthermore, the fuse is designed for use in high ambient temperatures, making it ideal for outdoor applications.

In conclusion, the S505-2.5-R fuse is a dual element time-delay fuse that is designed for both over-voltage and short circuit protection. It features a metal construction with a high breaking capacity, providing more efficient over-current protection than other types of fuses. It is mainly used in industrial, commercial, residential and agricultural applications and is suitable for use in aerial supply cables, electric motors, transformers and fluorescent lamps. The design of the fuse ensures reliable operation in high ambient temperatures.
