The Schneider Electric DF101 is a single-pole modular fuse holder designed for 10×38 mm cylindrical fuse links, used to protect electrical circuits against overloads and short circuits in industrial and residential electrical panels.

Manufactured by Schneider Electric (formerly Telemecanique), the device provides high reliability and operational safety. It is designed for installation on a standard 35 mm DIN rail, allowing easy integration into modular electrical distribution boards.

The fuse holder allows quick fuse replacement through a front-opening mechanism, simplifying maintenance operations. The device is compatible with gG, aM, and aR fuse types, commonly used for general protection, motor protection, and semiconductor protection.

The product complies with international standards for electrical protection devices and represents a reliable solution for power distribution systems, industrial automation, and photovoltaic installations.

⚠️ The device includes the safety warning “Do not operate under load”, meaning it must not be opened while the circuit is energized.
