Type 1+2+3 AC surge protector - Unipolar
Part Number: 29221022
DACN1-25VGS-10-440
- Type 1 + 2+3 AC surge protector
- VG Technology
- In: 25 kA
- Iimp: 25 kA on 10/350µs impulse
- No leakage current
- Unpluggable module for each phase
- Remote signaling
- Optimized to TOV
- EN 61643-11, IEC 61643-11 complied
The DACN1-25VG is an extreme duty Type 1+2+3 SPD designed to protect AC powerline at the main switchboard of an installation equipped with lightning rod, and in wind turbines' application, the low-voltage side of transformer and power side of convertor is the typical application.
Equipped with exclusive CITEL’s VG technology, the range achieves an high protection level, guaranteeing a maximum protection efficiency, a absence of follow and leakage currents, a simplification of use (no additional lightning arrester required) and a maximum lifetime.
