China, Beijing, November 8, 2016 - Littelfuse, Inc. (NASDAQ: LFUS) today announced the availability of the 507 Series fuse tubes. The 600VDC ceramic tube fuse has a 150A breaking current at 650VDC and is available in a compact 6x32mm package. The high DC rated voltage combined with the 1A to 8A rated current makes it ideal for overcurrent protection of high voltage DC circuits. Due to the increasing power density that circuits must handle, such miniaturized high-voltage fuses are the optimal solution for DC power supply overcurrent protection.
The 507 Series fuses are available in standard fuse tubes and axial lead designs, are RoHS compliant and 100% lead free. Typical applications for the 507 Series include various variable frequency drives (VFDs), photovoltaic (PV) inverters, DC-DC converters, and overcurrent protection for high voltage power supplies.
“We designed the 507 Series fuses to meet the needs of the industrial systems market,†said TIm Patel, Global Strategic Marketing Manager for the Littelfuse Industry 4.0 market. “Our goal is to provide circuit designers with the product choice to deliver the highest power to the motor in the smallest package size.â€
All 507 series fuse tubes have the following main advantages:
• Complete overcurrent protection for high voltage DC circuits such as VFDs, motor drives and power inverters due to their high rated DC voltage of 650V, rated breaking current of 150A at 650VDC, and compact 6x32mm package.
• Suitable for DC circuits in photovoltaic (PV) inverters and uninterruptible power supplies (UPS) operating up to 650VDC with short-circuit currents up to 150A.
• Small package size reduces the difficulty of creating a compact design for power conversion equipment that requires higher operational efficiency.
• Rated currents from 1A to 8A, ideal for most 200V and 400V VFDs on the market.
• Wide operating temperature range (-55°C to 125°C) for reliable protection in ultra-high working temperatures.
