Designed with power in mind, the series 300XBX is a high-power relay used for power transfer circuits in PC servers, power supplies, test equipment and in other high capacitance/high voltage devices. Using 2 mm contact gaps with arc barriers that can switch up to 600 volts AC (rms), this series meets European contact gap requirements. Rated at 30 amps, the 300XBX is a DPDT relay that features a high voltage coil rated from 6 VAC or DC up to 250 VDC or 240 VAC (rms), comes with a quarter-inch quick-connect terminals for easy and reliable installation and offers a variety of cover configurations. The 300XHX is a SPDT version, rated at 10 amps @ 150 VDC when equipped with a permanent magnet blowout. Optional Features include: Indicator lamp to signal that the coil is energized, Blow out magnets for arc quenching in high voltage DC switching applications. Clear polycarbonate housing, Manual test button. The 300 Series is the first UL approved Relay that can substitute the old "open-frame" relays for a smaller enclosed device, adding safety to your product without sacrificing it's ratings.
