Product Description
Siemens 3RW4038-1BB04 soft starter is engineered to gently ease your three-phase induction motor rated 37 kW and operating at 400V AC into operation. By controlling the supply of voltage and current during startup, it effectively prevents damaging surges to the motor and extends its operational lifespan.
The device also facilitates a smooth wind down by gradually reducing the generated torque, avoiding abrupt stops. Integrated thyristors are bridged by bypass contacts during normal operation, which minimizes waste heat generation and keeps the system running efficiently and cooler.
Designed for industrial environments, this soft starter supports screw or snap-on mounting options, allowing flexible installation according to your setup. Its compact dimensions of 170mm length, 170mm depth, and 55mm width maximize board packing efficiency and save valuable space.
Rated with an ingress protection of IP00, it is suitable for dry and controlled environments. The operating temperature range from -25°C to +60°C ensures reliable performance across demanding industrial conditions.
This soft starter complies with multiple international standards including RCM, CCC, CE, CSA, ATEX, UL, and EAC, guaranteeing safety and quality. Its concentrated and energy-saving design aligns with sustainable industrial practices.
Commonly used in motor-powered equipment like conveyor belts, compressors, and piston pumps, the starter is ideal for preventing pressure surges that can reduce system lifespan. Controls motor start-up voltage and current to avoid surges.
Gradual motor torque reduction for smooth wind down. Compact and efficient size for optimized space usage. Flexible mounting with screw or snap-on options. Wide temperature tolerance for industrial use. IP00 protection rating for indoor environments.
