150A DC contactor relay features energy-saving board, rated working voltage up to 9V-36V (including 12V DC contactor and 24V DC contactor for options). High stability DC contactor for electric vehicles provides optional auxiliary contact 1NO for better performance, longer electrical life 10,000 times, compact size and easy installation.


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 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 comes with the inert gas as the medium after vacuuming, can be used for flexible cutting of high current and high voltage. Optional auxiliary contact is available to achieve bidirectional power breaking.

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. DC contactor relays are widely used for DC power control, battery switch control, circuit safety protection, etc.

150A DC Contactor Relay On and Off Transform


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.
