GDL1/10

The **Mersen GDL1/10** is a premium **250V time delay glass fuse** engineered for robust overcurrent protection in demanding industrial environments. Part of Mersen’s trusted **GDL series**, this fuse combines precision engineering with a **0.1A current rating** and a **250V voltage rating**, making it an ideal solution for sensitive electronic circuits, control systems, and power supplies where transient surges must be tolerated without nuisance tripping. With a compact **1/4" x 1 1/4" (6.35mm x 31.75mm) glass body**, the GDL1/10 is designed for space-constrained installations, offering engineers and technicians a reliable, space-saving protection component that meets stringent safety and performance standards. **Key Features and Technical Specifications:** The GDL1/10 time delay fuse is specifically designed to provide **selective coordination** in electrical systems by allowing brief overcurrent conditions—such as startup surges or inrush currents—to pass without interrupting operation. This time-delay characteristic is critical in applications where momentary overloads are normal, such as motor starting circuits, transformers, or inductive loads. The fuse’s **0.1A (100mA) rating** ensures precise protection for low-current control circuits, instrumentation, and sensitive semiconductor devices. Its **250V rating** supports use in both AC and DC applications up to this voltage level, making it versatile across a wide range of industrial, commercial, and instrumentation systems. **Typical Applications Across Industries:** The Mersen GDL1/10 is widely deployed in industries that demand **high-reliability circuit protection** with minimal downtime. Common applications include: - **Industrial Control Panels**: Protecting PLCs, relays, and sensor circuits from overcurrent events. - **Power Supply Units**: Safeguarding transformers, rectifiers, and DC power distribution systems. - **Telecommunications Equipment**: Shielding sensitive telecom hardware from transient faults. - **Automotive and Aerospace Testing**: Used in test benches and calibration equipment where precise current thresholds are required. - **Medical Devices**: Ensuring patient safety in diagnostic and therapeutic equipment by preventing overcurrent conditions. **Why Choose Mersen for Time Delay Fuses?** Mersen, a global leader in electrical protection and thermal management solutions, has built a reputation for delivering **high-integrity components** that meet international safety standards.
