New: FRM-A and DRM-A for demanding requirements

Very small, light and robust: These are increasingly important requirements of the Avionics
industry for the components of their suppliers. SCHURTER addresses this need with the FRM-A and DRM-A fuse holder/fuse combination.

An optimised unit for demanding requirements:

  • Designed and optimised for Avionics applications

  • FRM-A: Ultra-compact, light and made for
    harsh environmental conditions

  • DRM-A: Whisker-free ceramic fuse with fast
    tripping characteristics

Thermal Protection

Electrical and electronic equipment can not always count on constant voltage, constant current or constant working temperatures. Various influences lead to fluctuations, which must be secured by suitable means.

Fuse Holders

We offer the world's broadest range of open and closed fuse holders.

Our fuse holders are also offered in the form of fuse drawers, which guarantee a safe and simple power supply to the devices in combination elements with IEC 60320 device connectors.

Chip Fuses

Our portfolio contains a wide range of high-quality chip fuses. These have been specially developed for precise and low-loss overcurrent protection in secondary circuits. Six different types in chip sizes from 0402 to 1206 guarantee compact and effective protection in the event of a fault.

SMD Fuses

We offer a wide range of solutions for primary and secondary protection directly on the circuit board. The fuses UMT-H, UMF 250, and UMT 250 offer compact as well as precise solutions, which furthermore are pulse resistant. The range is complemented with the two types UMZ 250 and UMK 250, with preassembled clips and fuse links.
