How to correctly choose a general purpose 10A relay? First of all, to understand another problem, it is first necessary to conduct a thorough investigation and in-depth understanding of the nature, characteristics and requirements of the control circuit of the 10A relay control object.

Secondly, the various characteristics of the 10A relay itself, such as principle, working conditions, technical parameters, structural technical characteristics, specifications and models, should be fully grasped and carefully analyzed. Secondly, according to the principle of value engineering, from the perspective of advancement, rationality, availability and economy, correctly select and use 10A relays.

The principle of correct selection of 10A relay is as follows:

(1) The main technical performance of the 10A relay, such as contact load, working time parameters, mechanical life, electrical life, etc., should meet the requirements of the entire system;

(2) The structure type (including installation method) and external dimensions of the 10A relay should meet the requirements of the operating conditions.

(3) Economic rationality.

Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, conversion circuit and so on. The above three points are the general principles for selecting general-purpose relays.
