    When placing an order, please be sure to clarify the following information: product name, complete model, control coil voltage specifications, mounting frame type, whether auxiliary contacts are required, and order quantity, etc. This information is critical to ensuring the accuracy and timely processing of orders. For example, you can state your order like this: HV DC Contactor HEV50-\u25a1-\u25a1\/24V 100pcs, which means that the load you need has a rated current of 50A and no auxiliary contacts are required. The mounting bracket is selected by default and the control coil voltage is 24V, the order quantity is 100 pieces. In addition, if you have special voltage specification requirements, special orders can be made to meet your specific application requirements. We will do our best to provide you with the products you need and ensure they meet your technical specifications and usage environment.<\/div>\n","protected":false},"excerpt":{"rendered":"
