Description

The DCNLJ Series Max High-Current High-Voltage DC Contactor Relay is designed for high-current contact switching in electric control systems of communication power supplies and uninterruptible power supplies (UPS) as well as other industrial and vehicle applications. This normally open relay comes in a variety of configurations to suit your application requirements. Polarized models with main contacts rated for 96V (110V max) and non-polarized models with main contacts rated for 48V (60V max) are available with a continuous current rating of 125A, 200A, or 250A. Available coil options for the DCNLJ contactor relay vary depending on the model’s continuous current rating and include 12V , 24V , 48V , and 60V .

• Be sure to use a washer to prevent screws from loosening. Tighten the screw so that the torque is in the range specified below. Exceeding the maximum torque can lead to product rupture.
• Please refer to the drawing for connection polarity.
• Do not use dropped products.
• Avoid installing the product in a strong magnetic field (Close to the transformer or magnet), or near an object with heat radiation.
• Electrical life Please use under load capability and life cycle so as not to cause a function failure. (Please also treat the contactor as a product with specified life and replace it when necessary). It is possible to make parts burn around the contactor once operating failure happens. So it is necessary to take layout into account to make sure power shall be cut off within 1 second.
• Do not let particle and oil stain on the main terminal with which the load shall make a reliable contact or it will cause a lot of heat.
