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.

Eta mcbs

MCBs are essential components in electrical systems. They are designed to protect applications and electrical loads against the dangerous consequences of overcurrents.

While MCBs according to UL 1077 provide additional protection for low voltage applications, the MCBs according to UL 489 are designed to provide reliable protection for a wide range of applications and voltage ranges.

Our thermal-magnetic MCB portfolio (4230-T) includes both UL 1077 and UL 489 versions have rated currents from 1 to 63 A with different characteristics and numbers of poles. The 4230-T…U product group (UL 489) is suitable for circuit protection in AC or DC networks, the 4230-T…E product group (UL 1077 / EN 60947-2) is designed for additional protection.

The UL 508A standard specifies the requirements for the construction and installation of control panels to ensure that they comply with electrical safety standards. Among other things, the standard covers the design, wiring and operation of control panels and guarantees that they can control electrical systems safely and reliably.

Our 4230-T MCB is suitable for use in switchgear according to UL 508A. Each load can be individually protected according to the standard.

Typical Applications:

  • Automotive manufacturing
  • Chemical, oil and gas industry
  • Automation and building technology

Gesis micro 2

This connector system outside fixed installations enables equipment like luminaires in furniture and shelving to be connected securely and flexibly in an extremely easy and minimalistic manner.

The gesis® MICRO connector system impresses with its round shape and small diameter of just 8 mm. These ideal properties enable the cable assemblies to be laid and installed easily and unobtrusively.

The 2-pole and 3-pole connector system (GST08i2 / GST08i3) can be guided through drilled holes with a diameter of 8 mm with ease, without the need for special tools.

Given that gesis® MICRO is optimally matched to the entire gesis family, this enables a completely integrated system.
