High voltage DC contactor features 350A rated current, optional auxiliary contact 1NO and 9V-36V coil rated voltage. High stability DC contactor relay provides energy-saving board, well suits for DC power supply control, battery switch control, circuit safety protection, etc. Reasonable DC contactor with reliable quality.
Features
1. The reliable sealing enables the DC contactor relay to be used in harsh and explosion-proof environments for a long time and its internal components including coils and contacts are not oxidized. The DC contactor also features fast switching action, low energy consumption, low heat generation, long life, small size and light weight.
2. The DC contactor relay can control high voltage and high current and has auxiliary contact for better performance. The contact is protected by a strong magnetic arc blowing, thereby prolonging its service life.
3. Smaller arcs make the contactor more effective and safer to use. The relay is sealed with inert gas, which ensures that there is basically no arc between the contacts when the contactor is in action and magnetic blow-out is adopted to ensure safety.
4. High stability. The internal mechanism and structure of the contactor are completely sealed with the inert gas, free from the interference of adverse external factors and the contact resistance remains stable for a long time.
5. Wide application. The DC contactor relays are equipped with energy-saving circuit boards, widely used for DC power control, battery switch control, circuit safety protection, etc.

DC Contactor Relay Dimension (Unit: mm)
Notes:
1. When installing the DC contactor relay, a washer should be used to prevent the screw from loosening.
2. DC contactors with polarity shall be wired according to the marks on the product cover, there are no any requirements of incoming and outgoing lines for nonpolarity contactors.
3. Do not install the contactor in a strong magnetic field environment (near the transformer or magnet) or near the heat radiation source.
4. Do not use the contactor when its switching capacity and service life parameters are exceeded.
5. Make sure the working environment temperature between -40°C ~+85°C, too high temperature is easy to accelerate the diffusion of internal inert gas and it is necessary to avoid using the product under too high temperature environment.
6. When the resistive load is connected, it shall be used according to the rated parameters of the main contact. If the inductive load (L load) is connected and L/R > 1ms, the inductive load shall be connected in parallel with the surge current protection device.
7. During wiring and installation, to ensure that the main outgoing end and terminal head are clean and tightened to avoid excessive heating at the connection of outgoing end.
