Soft starter – SH51

BLEMO SH51 soft starter

Smooth engine start-up for powerful standard machines

With the SH51, BLEMO offers a modern soft starter for standard industrial applications where controlled motor start-up, high operational reliability and cost-effective operation are crucial. The SH51 is designed for applications ranging from 4 to 400 kW, 17 to 590 A and 208 to 600 V, and is ideal for machine builders, plant manufacturers and industrial companies that prioritise reliability, efficiency and easy integration.

Thanks to its integrated bypass, intelligent monitoring, torque control and Modbus communication, the SH51 is a powerful solution for a wide range of industrial applications.

Why the SH51?

The SH51 has been designed for applications where motors need to start up reliably, without damaging the equipment and without causing unnecessary load peaks. Instead of hard direct starts, the soft starter enables a smooth start-up, thereby reducing mechanical and hydraulic stresses on the system.

This protects the engine, drivetrain and connected components, reduces wear and helps to minimise downtime and maintenance costs. At the same time, the SH51 improves process stability and ensures smooth, controlled plant operation.

Product information

The SH51 is more than just a standard soft starter. It combines controlled motor start-up with intelligent monitoring and high energy efficiency. This means users benefit not only from a smooth start-up, but also from greater transparency during operation.

The integrated monitoring of key operating data enables better assessment of load conditions, faster detection of faults and more targeted planning of maintenance measures. This increases the availability of your plant and provides a solid foundation for cost-effective and safe operation.

In mechanical and plant engineering in particular, it is essential that components can be integrated quickly and commissioned without delay. The SH51 is designed precisely for this purpose. Its compact design, integrated communication and practical features enable it to be easily integrated into existing systems.

This saves time during planning, wiring and commissioning, whilst also reducing the workload involved in the project.

Rising energy costs make efficient drive solutions more important than ever. The SH51 supports energy-efficient operation thanks to its integrated bypass and an efficiency of up to 99.5%.

In addition, functions for monitoring power and energy consumption are available. These enable consumption to be tracked more transparently, load profiles to be better understood, and potential savings to be specifically identified. This reduces operating costs and supports modern energy management within the facility.

  • User account management and role-based access control
  • Restrict ports or services and disable them
  • Threat intelligence
  • Firmware update with cybersecurity

The SH51 has been designed for heavy-duty use in industrial environments. It offers outstanding operational reliability, dependable safety features and a durable design for daily use in machinery and plant.

This makes the SH51 a future-proof solution for businesses looking for a high-performance soft starter featuring state-of-the-art technology and excellent practicality.
