Overview

The Littelfuse L60S003 is a high-speed fuse designed for protecting power semiconductor devices in industrial applications. Rated at 600V AC and 3A, this fuse is part of the L60S series, which follows the traditional North American style. It is primarily intended for replacement purposes in existing electrical systems where fast-acting overcurrent protection is required. The L60S003 quickly interrupts fault currents to safeguard sensitive power electronics, reducing the risk of damage and costly downtime. This fuse is a reliable solution for maintaining operational integrity in equipment utilizing power semiconductors. Note that for new designs, Littelfuse recommends the L70QS series for advanced features and enhanced protection capabilities. The L60S003 is manufactured in the US and carries the SKU LT602003CS.
