The Bourns 1250-1S-400 is a 1-pole general duty AC Surge Protective Device (SPD) from the 1250 Series. It features a Max Continuous Operating Voltage (MCOV) of 420V and a TOV withstand of 440V. The device is rated for a nominal discharge current (In) of 20kA and a maximum discharge current (Imax) of 50kA per 8/20µs impulse. It achieves a Voltage Protection Rating (VPR) of 1200V and a Short-Circuit Current Rating (SCCR) of 100kA.
The SPD is designed for DIN Rail mounting and uses a base + module form factor. It offers screw terminal connections accepting up to #6 AWG wire. The enclosure is made of thermoplastic rated UL 94V0, and the device is IP20 rated. It includes remote signaling contacts and integrated thermal protection, along with a visual fault indicator. Operating temperature range is -50°C to 85°C, and it is suitable for altitudes up to 4000m. The 1250-1S-400 is RoHS compliant and carries CE, CSA, and UR approvals. It is intended for installation at service entrance and branch panels to protect against transient overvoltages.
