Littelfuse, Inc. (Littelfuse) introduces a compact, fast fusing 500VAC ceramic tube fuse with a rated current of 1.6A to 12.5A. The 514 series ceramic tube fuse has a rated interruption current of up to 5000A at an AC voltage of 500V, making it an ideal choice for high-voltage AC power line protection in HVAC and industrial systems. Its comprehensive design improves reliability by reducing the effects of temperature cycling and vibration. Its size is only 6.3mm x 32mm, allowing circuit designers to free up the circuit board space required to protect components.
The 514 series fuses are suitable for high energy efficiency and high-power applications in the home and building automation markets, including HVAC equipment and smart meters. Industrial market applications include uninterruptible power supply (UPS), three-phase power supply, and renewable energy.
The low rated current combined with high breaking capacity of the 514 series is unique in such a small fuse size, "said Ben Zheng, Global Product Manager at Litteluse
The 514 series 500VAC ceramic tube fuses have the following key advantages:
The high rated AC voltage and rated interruption current of 5000A under 500V AC voltage conditions make it an ideal choice for AC circuits in uninterruptible power supplies with AC working voltages up to 500V and short-circuit currents up to 5000A.
The rated current is 1.6A to 12.5A, providing reliable overcurrent protection for high-voltage AC circuits.
The small-sized (6.3mm x 32mm) ceramic tube body can achieve a more compact design for power conversion equipment that requires higher energy efficiency. This fuse is suitable for most commercial low-power power supplies.
The wide operating temperature range (-55 ° C to 125 ° C) ensures reliable protection in extreme temperatures and harsh environments.
The above is an introduction to the characteristics of Littelfuse ceramic tube fuse 514 series products. Welcome to consult and cooperate.
