What is a Circuit Protection device?

A circuit protection device is a fail-safe device that originates a disruption in an electrical circuit when it recognizes an excess and unsafe power load in a circuit. The main aims of circuit protection are to localise and isolate the situation or fault and avert and minimize any unnecessary power loss.

What Do We Supply?

We have broad selection of circuit protection devices, including:

Circuit breakers

Thermal circuit breakers

Thermal-magnetic circuit breakers

Magnetic circuit breakers

Hydraulic-magnetic circuit breakers

Fuses

LV fuse links

LV fusegear

Schurter AMO 10.3x38 High Performance Fuse

AMO 10.3x38

High Performance Fuse for Automotive Applications

Very high rated current up to 50 A
Safely interrupting 800 VDC
Versatile mounting options

With the AMO 10.3x38, Schurter launches a high-performance fuse for particularly high voltages up to 800 VDC and currents up to 50 A, which is particularly suitable for automotive applications.

High voltages and high currents occur in electric vehicles in numerous places. Their battery packs with several thousand rechargeable cells store enormous amounts of energy. This in order to meet customer requirements concerning driving performance and range by still providing the shortest possible recharging times. To safeguard this level of power, you need highly reliable high power fuses. Such fuses are required, for example, in the BMS (Battery Management System), for on-board and off-board chargers, DC-DC converters and other systems exposed to high voltages.

Welding Is More Reliable
A weak point of every fuse is the connection between the melting wire and the contact cap. This connection is usually done by a solder joint. In the fuse production process, however, this technology brings quite many difficulties. Creating the connection by welding increases the reliability by far. SCHURTER uses a new, patented process which guarantees highest reliability.

Versatile Mounting Options
The new fuses of the AMO series offer a multitude of possible mounting options. In addition to the classic mounting directly on a printed circuit board, screwable version for surface mounting or even axial mounting are available.
