2CTB815799R3100 - OVR ZP+ 3N 12.5-255 MCB6

The 2CTB815799R3100 ABB - OVR ZP+ 3N 12.5-255 MCB6 is a surge protective device (SPD) designed to protect electrical installations from transient overvoltages. These overvoltages can be caused by lightning strikes or switching operations. This SPD is a Type 2 device, suitable for installation in sub-distribution boards. It provides protection for three-phase networks with neutral (3N). The OVR ZP+ series features a pluggable design, allowing for easy replacement of the protection module in case of failure. It has a voltage protection level Up of 1.25 kV. The maximum discharge current Imax is 25 kA. The nominal discharge current In is 12.5 kA. It also integrates a miniature circuit breaker (MCB) with a 6A rating for overcurrent protection.
