EMC Filters

What is are EMC Filters?

An EMC or EMI filter is an electronic device used to reduce electromagnetic interference (EMI) in a power supply. It is typically used in power supplies, such as those found in computers, TVs and other electronic devices. The filter works by blocking the high-frequency noise generated by the power supply, allowing the device to operate more efficiently and with less interference.

What Do We Supply?

We supply an extensive range of EMC filters, including:
DC Filters
Single-Phase Filters
3-Phase Filters
IEC Inlet Filters and Modules
EMC/IEC Chokes
PCB Filters
Feedthrough Filters
Pulse Transformers

EKO: High-Performance HV Fuses for Industrial and Energy Applications

  • Rated voltage: 1000 VDC (1250 VAC available for
    selected series)
  • Rated currents: 50 – 1100 A
  • Breaking capacity: 50 kA DC (100 kA AC for
    selected series)
  • Characteristic HV Fuse Mounting Flush End,
    DIN-Rail, US Style Bolted Tag, Bolt-on

The EKO series is engineered for demanding high-voltage environments, offering protection up to 1000 VDC (and 1250 VAC for selected models) and current ratings from 50 to 1100 A. With a breaking capacity of up to 50 kA DC, these square-body fuses deliver safety and reliability.

Designed for robust performance, the EKO series withstands mechanical vibration, shock, chemical exposure, and extreme temperatures from -40 °C to +125 °C. Its ceramic housing and tin-plated copper alloy terminals ensure durability and stable electrical characteristics even under harsh conditions.

Choose from Flush End, DIN-Rail, US Style Bolted Tag or Bolt-on to simplify integration into diverse systems. Optional indicators and microswitches enable easy status monitoring.

The EKO series meets IEC, UL, and GB/T standards and complies with CE, RoHS, and REACH directives, ensuring global acceptance and peace of mind.

Schurter EKO fuses combine high performance with proven safety—your trusted choice for modern high-voltage protection.

Schurter MSM II-Switch with Common Anode Control of RGB LED

Schurter MSM

MSM II-Switch with common anode control of the RGB LED

  • Optimised for industrial control architectures
  • Usual SCHURTER Metal Line quality
  • Protection class IP67

The well-established MSM II mechanical switch family is growing. With the MSM II (Common Anode), Schurter is introducing a variant that uses a common anode to control the RGB LED illumination. This combines the familiar robust mechanics with visualization technology for clear feedback, easy integration, and maximum reliability in control and operating solutions.

RGB LEDs can be controlled either via a common anode (+) or a common cathode (–). While with common cathode all negative poles are connected together and the colors are controlled individually via the positive pole, the common anode variant does the opposite: all positive poles are connected, and the color channels are switched separately to ground.

The MSM II (common anode) offers maximum compatibility with modern driver ICs, PLC outputs, and microcontrollers, which are predominantly designed for common anode control. This facilitates integration thanks to a simple signal structure and reduced wiring requirements.

The combination of tactile precision, IP67 protection, robust design, and flexible RGB signaling makes the MSM II switch ideal for a wide range of applications, particularly in industrial control units such as control panels, production facilities, building automation, and access solutions.
