DT17510R DT1 DIN Rail Surge Protection Class I+II, 1+0 Mode

Surges and voltage transients are a major cause of expensive electronic equipment failure and business disruption. Damage may result in the loss of capital outlays, such as computers and communications equipment, as well as consequential loss of revenue and profits due to unscheduled system down-time. nVent ERICO offers multiple series of surge protective devices (SPDs) suitable for a vast range of applications that provide reliable protection from voltage transients on power distribution systems. The DT1 Series DIN Rail Surge Protective Devices provide reliable and efficient protection against voltage transients within the IEC Class I and UL Type 1CA environments. Tested and independently certified to the IEC and UL standards, the DT1 Series provides a range of compact, safe and high surge rated performance features for the harsh IEC Class I environment and suitable for protection within a wide range of applications.
