The Siemens 3RK1903-0CD00 is a meticulously engineered spacer module designed to complement the ET200S direct starter range. This component is particularly recommended for applications where the ambient temperature exceeds 40 °C or when the starter's rated current is 6.3 A or higher. Its primary function is to ensure optimal spacing within the system, facilitating adequate air circulation and heat dissipation, which is crucial for maintaining system integrity and performance in demanding environments.
Crafted with precision, the 3RK1903-0CD00 boasts an IP20 protection class, ensuring that it is safeguarded against solid objects larger than 12mm but not against water. The module's dimensions are carefully considered, with a mounting height of 195 mm, an installation width of 15 mm, and an installation depth of 64 mm, making it a compact yet effective solution for space management within electrical assemblies.
This spacer module is an essential component for those seeking to enhance the operational reliability and longevity of their ET200S direct starters, especially in conditions where elevated temperatures or higher current loads are a concern. Its robust design and compatibility with the ET200S series make it a valuable addition to any industrial control system where precision and durability are paramount.
