PSC4-25/400 TTIR

Modular plug-in surge protection devices

For the protection of low voltage equipment against transient voltages and current surges from atmospheric origins (lightning) as well as transients produced by switching characteristics such as in switching of distribution networks, transformers, motors, etc. Suitable for first level of protection with incoming power supply panels and areas with greater exposure to lightning. For installations usually provided with external lightning protection systems.

Features:

• Capable of protecting equipment from direct lightning strikes
• High discharge capacity 10/350 ¼: 12.5kA or 25kA per phase
• Provides protection for most sensitive equipment (IEC 60634-4-443 category 1)
• Type 1+2 / Class I+II lightening current and surge arrestor (combined in a single device)
