TOMZN 2P 600V DC SPD 20kA/40kA, DC Surge Protector

TOMZN 2P 600V DC SPD 20kA/40kA – DC Surge Protector for Solar Systems

The TOMZN 2P 600V DC Surge Protective Device (SPD) is a high-performance solution engineered to protect DC electrical systems—especially photovoltaic (PV) installations—from damaging transient overvoltages caused by lightning strikes, switching operations, or grid disturbances. This 2-pole (2P) SPD is rated for use in 600V DC circuits and offers surge discharge capacities of 20kA nominal and 40kA maximum, making it a reliable safeguard for your solar power infrastructure.

Designed with PV systems and DC applications in mind, the SPD can be easily installed in combiner boxes, DC distribution panels, or inverter input sections. The plug-in module design allows for easy replacement and maintenance, while its DIN rail mounting ensures quick integration into new or existing systems.

Built with high-quality components, the TOMZN SPD features thermal disconnection mechanisms and status indication windows to alert users of failure or degradation. The flame-retardant housing adds another layer of safety, providing long-term durability even under extreme environmental conditions.
