New general duty SPDs with pluggable/replaceable modules are designed to meet high-risk electrical service entrance and branch panel protection requirements

RIVERSIDE, Calif., July 5, 2023 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, today introduced a high-performance AC Surge Protective Device (SPD) Series. The Bourns® Model 1250A Series SPDs are a new family of DIN Rail general duty SPDs with pluggable/replaceable modules offering surge rates up to 50 kA in different configurations. Bourns specifically designed its Model 1250A Series SPDs to meet high-risk electrical service entrance and branch panel protection requirements of high power, sensitive energy generation and distribution terminals such as EV fast chargers and battery energy storage systems (BESS).

Because sustained abnormal overvoltage high-energy surges can cause SPDs and/or MOVs to go into a thermal runaway condition that could lead to device overheating and create a fire hazard, Bourns' latest SPD products feature an Advanced Thermal Disconnector (TD+). This feature has a self-extinguishing mechanism that helps increase device safety during catastrophic end-of-life events. These new SPDs also come with an additional window fault indicator and remote auxiliary output signal providing the ability to monitor the status of the device.

The Bourns® Model 1250A SPD Series is available now and is RoHS* compliant. This series is a UL recognized Type 4, Type 2 Location SPD, passed short circuit current rating (SCCR) 200 kA without external fuse or circuit breaker, and complies with IEC 61643-11 standards.
