It is similar to the usual understanding of overcurrent protection - a way of protecting the action of a protective device when the current exceeds the predetermined maximum value. Overcurrent protection is when the current flowing past the protected part exceeds a pre set value, the protection device starts, and guarantees the selectivity of action with time limit, so that circuit breaker trip or alarm signal is given. The current load capacity of the ST terminal is protected by the resistance of the terminals of the terminals.

Each wiring terminal has its own current level. When the terminal current exceeds the load of the PCB terminal, the wiring terminal will fail, causing short circuit and so on. The current load capacity of the terminal and connector of the printed circuit board depends on a number of technical parameters. In order to achieve the required load capacity, the product needs to meet a variety of requirements:

1. Product structure

The more stable the product structure is, the stronger the terminal current load capacity is.

Two. Materials used

The thickness and width of the conductor of the terminal should be in accordance with the requirements that can be passed through the current, and the selection of insulation material is also related to the current load capacity. The slower the aging speed of the insulation material, the stronger the current load capacity of terminal terminals.

Three, adjacent number of adjacent digits

The number of terminals should conform to the installation requirements. For plug and pull terminals, the plugs and sockets should be corresponding. In addition to manufacturers' consultation, they can't match products with different needle distances without authorization, so as not to damage the equipment.

Four. Environmental temperature

The higher the ambient temperature is, the weaker the current load capacity will be. This is why electrical equipment needs a good cooling environment in order to ensure that the equipment works well.

The current load capability is one of the specifications of the wiring terminals. It means that under normal circumstances, when 5 adjacent terminals have current passing at the same time, they will neither cause damage to the components due to heating, nor will they affect the function of the components.
