Citel DAC50S-31-440 SPD, type 2, 3P+N, 440VAC, 20kA

The Citel DAC50S-31-440 is a type 2 surge protection device designed for three-phase with neutral applications at 440VAC. With a 20kA surge handling capacity, it provides robust protection for industrial control panels and electrical systems against transient overvoltages and lightning-induced surges.

This SPD is engineered for installations requiring reliable coordination between primary and secondary surge protection stages. The 3P+N configuration makes it suitable for three-phase power distribution systems where neutral conductors must be protected alongside phase conductors.

Ideally suited for industrial environments, manufacturing facilities, and commercial control systems, the DAC50S-31-440 delivers consistent performance and safety compliance for critical electrical infrastructure.
