Siemens 3RW4026-1BB14 SIRIUS 3RW4026 Soft Starter 5.5/11kW

Product Description

Siemens SIRIUS Soft Starter, 3RW3 & 3RW4 Series
- Siemens 3RW4026-1BB14, The Siemens 3RW4026-1BB14 is a Sirius Soft Starter from the 3RW40 Range. This starter is used to start three-phase induction motors with reduced torque & reduced starting current. The starter has been developed to enable the soft run-up & slow-down of DC motors. It helps the mechanical power transmitting elements of the machine at the start by reducing the starting torque & efficiently protects the network from dangerous spikes through reduced power consumption. Through the continued increase of the motor voltage, the network, the motor & load are optimally protected against voltage overload. The 3RW40 Soft Starter is small, inexpensive & can be easily combined with the SIRIUS contactors, power switches & overload relays. The SIRIUS 3RW40 Soft Starter comes with additional functions, i.e. selectable solid-state motor overload, intrinsic device protection & adjustable current limiting, as well as a new patented two-phase control method (Polarity Balancing) that is unique in this rating range. Application areas include, fans, pumps, building/construction machines, escalators, transport systems, air conditioning systems, ventilators, assembly lines, compressors & coolers & operating mechanisms.
