Battery Disconnect & Power Distribution - Truck & Bus

Explore our full range of fuse types and sizes. As a leading manufacturer of electrical components, we offer a broad selection of fuse types, such as electrical and industrial fuses. Our industrial fuses are designed to deliver reliable overcurrent protection across a wide range of applications. From power and automotive fuses to axial, cartridge, surface-mount, specialty, and medium-voltage options, our solutions ensure safe and efficient current regulation for virtually any system or device.

EVs and industrial electronic control systems need robust power management solutions. Littelfuse’s high-voltage dc contactor relays meet those needs while also providing high-current circuit protection. Our contactor relays come with continuous current ratings up to 500 A and maximum voltage ratings up to 1.8 kV dc. Some versions incorporate pulse with modulation (PWM) technology to reduce power demands for keeping contacts closed. Common applications include EV charging stations, uninterruptible power supplies, and dc motor controllers. Browse our off-the-shelf dc contactors or partner with us on your next design.

Transient voltage suppressor (TVS) diodes defend against damage from overvoltage events by responding within picoseconds to shunt current to ground. The classic example of TVS diode use is protecting outdoor telecom equipment from lightning strikes. Littelfuse produces surface mount and leaded diodes and TVS diode arrays for that, as well as TVS diodes for cars, personal electronics, data cables, and household appliances.
