Type 2 arrester for the DC side. Protects PV system components like inverters and PV modules against overvoltage. Available in 2 versions: ≤ 1170 V and ≤ 1500 V.
Permanent availability is the top priority of onshore and offshore wind turbines. Stay on the safe side – With a comprehensive protection concept.
VCSD 40 IP65 limits long-term, temporary and transient overvoltages. The voltage-controlled short-circuiting device of the d.c. decoupler limits a.c. voltages to a preset value without negatively affecting the desired d.c. potential.
Compact 3in1 arrester that protects three interfaces in a single device.
Particularly for process automation systems: Space-saving combined arrester module with LifeCheck® for protecting two pairs in 24 V d.c. systems with earthed negative pole.
