Bourns Releases New Surge Protective Devices (SPDs)

Hardwired AC Hybrid Surge Protective Devices (H-SPDs)

Model 1251 and 1252 Series

Bourns is pleased to announce the release of the Model 1251 and 1252 Heavy Duty AC Surge Protectors.

The Model 1251 Series is a high performance Type 1 Hybrid SPD designed to be installed on the line side

of the main service disconnect. The Model 1252 is a high performance Type 2 Hybrid SPD designed to be

installed on the load side of the main service disconnect. Both series are designed for either 120/208 Three-

Phase Wye or Single Phase 120/240 VAC circuits. The Model 1252 Series also includes ﬁ ltering for noise

mitigation.

The Bourns® Hybrid SPD (H-SPD) designs combine the technologies of a Metal Oxide Varistor (MOV) and

a Gas Discharge Tube (GDT) to provide fast-acting and low leakage performance over the life of the SPD.

Rated at 50 kA on a single 8/20 µs surge, the Bourns® Model 1251 and 1252 Series are designed for either

indoor or outdoor installation. Wiring options include a 20 inch, 12 gauge wiring stub that exits either the

right side or rear of the protector.

In the unlikely event of a failure condition, both series are designed with thermal disconnection safety

features as well as visual and audio indicators. All Model 1251 and 1252 Series products are listed to UL1449.
