Why are MS25 Motor Protection Switches an Industrial Standard?

1. Comprehensive 3-in-1 protection: fewer failures, lower costs

MS25 switches eliminate the need for several separate devices by combining three key functions:

• thermal protection (overload): reacts to current increases above the rated power, protecting windings from overheating.

• magnetic protection (short-circuit): instantly cuts off power during a short circuit, preventing costly damage.

• phase failure protection: critical for three-phase motors, where the absence of one phase can lead to immediate motor burnout.

2. Wide setting range – standardization in your machine park

The MS25 series includes a range of devices with various adjustment ranges that collectively cover currents from 0.1 A to 32 A. This allows you to base your entire facility’s protection on a single, proven system:

• precise matching: you select a device with a range corresponding to the power of a specific motor – from small pumps to large compressors and HVAC units.

• simplified operation: using one series throughout the plant means the same mounting logic, the same accessories, and consistent diagnostics for all machines.

4. Modularity and accessories: “custom-fit” configuration

The MS25 is a system that grows with your needs, thanks to extensive accessories:

• enclosures with IP54 / IP65 protection ratings.

• auxiliary contacts, signaling contacts, and undervoltage releases.

• enclosures with CEE or Schuko plugs, ready for “plug & play” operation.

5. Easy assembly and fast diagnostics

The MS25 is mounted directly on a standard 35 mm DIN rail. The two push buttons and clear status signaling make operation easier for personnel, resulting in faster installation, simpler diagnostics, and shorter service downtimes.

6. Certificates and compliance with standards

The safety of the MS25 series is confirmed by EN60947-4-1 and UL60947 standards. For investors and designers, this is a guarantee of reliability and assurance of trouble-free technical inspections of industrial installations.

7. Versatility of applications

A single solution standardizes protection across the entire company, from agriculture to advanced industry. MS25 units are ideal for:

• submersible and sewage pumps.

• compressors and air compressors.

• production lines and woodworking machinery.

• HVAC ventilation and air conditioning systems.

Summary: MS25 means real benefits for your business

MS25 motor protection switches are a proven solution that increases machine safety, reduces service costs, and saves time through easy installation. It is practical protection for anyone who values the continuity of their installation’s operation.
