Product Description

FEATURES

20A switching capability

High voltage DC relay for new energy

Electricity safety in accordance with lEC 60664-1requirements

A variety of installation options are available

Switch shape: (30.1×30.0×29.2) mm

 

ATTENTIONS

In case of loosening, please use washer when install the relay with M3 screw, and the torque within 1.4N.m ~ 2.2N.m; The push and pull

force for terminals is 49N for load terminals. The torque beyond the range may cause damage.

Please do not adhere foreign materials like oil on the termials and please use the wire with cross section area 4mm2 min., otherwise the

terminal parts may have abnormal heating.
 

DECLARATION

All the specification listed only for customer's reference. It is subject to change without notice.

For us, it is impossible to evaluate all the performance parameters of the relay for every possible application, thus the user should

choose the corresponding products according to the specific conditions of their own application. Any doubt, please contact us for more

technical support. However, it is the user's responsibility to determine which product should be used only

Corrected sentence: The rated voltage VDC is 12, 24, and 48. The pick-up voltage VDC does not exceed 9, 18, and 36. The drop-out voltage VDC is at least 1, 2, and 4. Translation explanation: 1. Grammar: "Rated voltage" has been changed to "rated voltage", "Pick-up voltage" has been changed to "operation voltage", and "Drop-out voltage" has been changed to "release voltage". 2. Vocabulary: More accurate Chinese translations have been used to convey the original meaning. 3. Structure: The sentence structure has been reorganized for clearer expression. As a professional translator, I have translated the original sentence into English while ensuring authenticity of vocabulary usage, fluent language expression, clear structure that aligns with native speakers' preferences.
