Bourns New Hybrid Surge Protective Device Offers Multi-Mode Protection in a Compact Design

Jan 15, 2020

Bourns has announced the Bourns Model 1202 Series. This Type 1 hardwired hybrid surge protective device (SPD) is designed for AC infrastructure applications. Bourns engineers have combined the company’s fast-responding Metal Oxide Varistor (MOV) technology with its low leakage Gas Discharge Tube (GDT) technology to deliver a device that provides consistent, long-life, reliable and enhanced protection performance. The Model 1202 Series employs a full multi-mode protection scheme that can be utilized in line-to-line, line-to-neutral and neutral-to-ground configurations.

The innovative hybrid design uses the GDT to isolate the MOV from the line voltage thus shielding it from transients and temporary overvoltage spikes that can potentially damage the MOV over time. The GDT’s ultra-low leakage also helps to reduce damage due to watt loss heating.

The Model 1202 has a nominal current rating of 10 kA and a short circuit current rating of 25 kA. The device’s LED indicators provide visual indication when the surge protector encounters any situation that requires its internal safety fusing to activate. In addition, the Series is IP66/NEMA 4x rated and can be used indoors or outdoors. As a Type-1 SPD, the Model 1202 requires no external line fusing or circuit breaker, and can be placed on the line side of the main service disconnect. The extensive features designed into Bourns’ latest hybrid SPD make it an optimal solution to protect against lightning threats, up to rated limits, and for AC power-induced problems in applications such as service entrances, branch and OEM panels, electrical infrastructures and in equipment and systems cabinets.

Available now, Bourns® Model 1202 Series is available in a 120 V_rms version as well as a 120/240 Split Phase version. Both models are RoHS compliant* and listed to UL 1449, Issue 4.
