Siemens SIRIUS Modular | Datasheet Preview

The SIEMENS SIRIUS modular industrial control products are both modular and easy-to-integrate into a control cabinet. The motor start protector circuit breakers are UL approved as Self Protected Combination Motor Controllers where all the required functions for a motor branch are provided in one device. The SIRIUS 2 contactors are equipped with conventional AC/DC and solid-state AC/DC operating mechanism options and are ideal for performing switching operations that are frequently repeated. Reversing contactors are fully-wired assemblies that lead to a notable reduction of wiring in the control circuit and help prevent wiring errors. The thermal overload relays are suitable for customers from all industries who want to guarantee optimum inverse-time delayed protection of their electrical loads, such as motors, under normal starting conditions. These relays have 5% to 10% less power consumption than previous solutions.
