Din-Rail mountable, Bourns ®  Model 1430 and 1440 Series SPDs feature high energy MOV technology with Thermal Disconnector to deliver an elevated level of protection 

RIVERSIDE, Calif., August 20, 2024 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, today announced its Model 1430 and 1440 Series Din-Rail DC Surge Protective Devices (SPDs). The two new series are IEC/EN 61643-31 compliant Class I + Class II / T1+T2 SPDs. Designed to protect DC power systems, the 14 new models offer protection voltage ranging from 48 VDC up to 1500 VDC, and feature high energy MOV technology. In addition, the Model 1440 Series features an Advanced Thermal Disconnector (TD+) to deliver an elevated level of protection that helps eliminate the need for upstream overcurrent protection. Both model series have a replaceable modular design, and also include a window fault indicator and remote alarm, providing enhanced surge protector operating status monitoring. 

These new SPDs help designers mitigate the risk of a thermal runaway condition that is caused by sustained overvoltage and surges that can potentially result in a fire hazard. 

Offering superior surge protection, they deliver up to 80 kA 8/20 μs per mode surge energy capability, and provide an impulse current capacity up to 12.5 kA 10/350 μs. The Bourns ®  Model 1430 and 1440 Series are ideal protection solutions for a broad range of DC-powered applications that include electric vehicle charging stations, battery energy storage systems (BESS), and green photovoltaic and wind energy systems. 

Bourns ®  Model 1430 and 1440 SPDs are available now and are RoHS* compliant. For detailed product information, please visit: www.bourns.com/products/surge-protective-devices/dc-power-surge-protective-devices.
