Siemens 3RW40 Soft Starter 480V AC, 22 kW, 3 Phase, Chassis Mount, IP20, 170mm x 55mm, Model 3RW4036-1BB14

Siemens 3RW4036-1BB14 Soft Starter is engineered to provide precise, reliable control over three-phase electric motors in demanding industrial environments. Designed for applications requiring smooth motor startup and shutdown, this device minimizes electrical and thermal stresses, thereby extending machinery lifespan and enhancing operational safety.

With a rated power output of 22 kW and compatibility with supply voltages up to 480V AC, the 3RW4036-1BB14 is suitable for heavy-duty tasks such as powering conveyor belts, pumps, and processing equipment. Its chassis mount form factor simplifies integration into custom or standard control panels, making it a versatile solution for industrial automation.

The integrated bypass circuit optimizes energy efficiency by reducing heat dissipation during running operation, while the device’s robust IP20 enclosure delivers physical protection against ingress and contact hazards. A broad operating temperature range from -25°C to +60°C ensures stable performance across diverse installation conditions, including outdoor and high-temperature settings.

Installation is streamlined thanks to front-facing screw terminals, which provide easy access for wiring and maintenance. The compact 170mm x 55mm size facilitates placement within space-constrained electrical enclosures, supporting both standalone and side-by-side configurations as required for multi-motor installations.

Advanced motor control features include reduced supply-voltage fluctuations during startup, safeguarding equipment against overloads and electrical surges. The integrated reset button offers rapid recovery and minimizes downtime if faults occur. The 3RW40 series design allows the Soft Starter to be used for controlled motor stopping, ensuring safe torque reduction and preventing abrupt mechanical wear.

Supported by international certifications (CCC, RCM, ATEX, EAC, CE, CSA, UL), the Siemens 3RW4036-1BB14 is suited for construction, manufacturing, chemical processing, and water treatment plants. Its concentrated, compact solution contributes to energy savings and meets the requirements of modern industrial automation systems.
