Overview

The Littelfuse CY10X38G12 is a fast-acting French cylindrical fuse (gL-gG) designed for the critical protection of cables against short circuits. For motor protection, time-lag (aM) variants are available. Manufactured by Littelfuse, a recognized leader in electrical safety components, this fuse ensures reliable circuit interruption. The gL-gG type provides immediate response to short-circuit events, safeguarding wiring integrity. The aM type offers time-delay characteristics, specifically engineered to withstand the temporary inrush currents of motors without nuisance tripping, while still protecting against sustained overloads and short circuits. These fuses are essential for industrial machinery, power distribution panels, and motor control systems where dependable protection is paramount. The CY10X38G12 series meets stringent quality standards, offering long-term reliability in demanding operational settings. Ensure your electrical systems are protected with Littelfuse's trusted fuse technology.
