Fuse link 5 x 20 1 A 010210

Ceramic protection for electronic circuits

The LEGRAND fuse link with dimensions 5×20 mm is a reliable solution for protecting electronic circuits sensitive to overloads. The ceramic construction provides high thermal and mechanical resistance, making it an ideal choice for applications requiring stable operation in harsh environmental conditions.

Operating parameters and technical characteristics

The device operates at a rated current of 1 A and an AC voltage of up to 250 V, offering a breaking capacity of 1500 A. The H tripping characteristic allows for short-term inrush currents without unnecessary circuit interruption - particularly important in the case of motors and pulse transformers.

Power loss at the rated current is only 0.7 W, which minimizes heat generation during normal operation. The device maintains full functionality within a temperature range from -25°C to +40°C, and during storage, it withstands extreme conditions from -40°C to +70°C. The nominal operating frequency is within the standard range of 50-60 Hz.

Application and compatibility

The miniature fuse link finds wide application in professional electronics - from switching power supplies and measuring instruments to industrial automation systems. The ceramic construction ensures stable operation even at high temperatures generated by semiconductor elements.

The product is compatible with all standard fuse bases for 5×20 mm links, facilitating integration into existing installations. The absence of an optical trip indicator is compensated by the high breaking capacity - the device effectively interrupts even the strongest short circuits.

Normative compliance and operating conditions

The fuse link meets the requirements of EN/IEC 60127 standards regarding miniature fuses, guaranteeing its safe operation in low-voltage installations. The ceramic body provides electrical insulation as well as resistance to moisture and mechanical vibrations.

Geometric dimensions (length 20 mm, width 5 mm) comply with international standards, enabling the use of the product both on PCB boards and in traditional switchgear. The manufacturer LEGRAND provides a 3-year warranty, confirming the high quality of workmanship and long-term reliability of the product.
