The new SCHURTER ALO series has been specifically developed for high-voltage electric vehicle applications and covers voltages up to 1000 VDC and currents up to 900 amps. With a high breaking capacity of up to 50 kA and the option of axial or bottom bolt-on mounting – available in either ceramic or resin housings – it provides maximum design flexibility.
The product line is available in a variety of voltage ratings from 250 to 1000 VDC and covers current ranges from 100 to 900A. It is designed for an operating temperature range of -40 to +125 °C. The housing materials are ceramic or resin, and the end caps are made of a tin-coated copper alloy.
A core advantage of the series is its wide range of products, which covers different designs, voltages, currents, and mounting methods, significantly reducing design effort for customers. Its robust construction ensures reliability in harsh environments and minimises the risk of housing cracks, terminal detachment, or resistance fluctuations. Safety is enhanced by proprietary filling and curing technology that prevents explosions, reduces fire hazards, and protects adjacent components from splinters.
Typical applications for the ALO series include PDUs, battery disconnect units, manual service disconnectors, all-in-one controllers, 2-in-1 electric drives, and battery management systems. The ALO series complies with the JASO D622, ISO 8820-8, GB/T 31465.6, and UL 248-20 standards, with the ALO11, ALO12, and ALO14 models already UL-certified.
This makes it a suitable choice for high-voltage protection in modern electric vehicle systems: powerful, safe, and customisable.
