For single-phase and three-phase alternating current single-phase and three-phase circuit breaker + class A differential.
Description
Transient overvoltage protection panel for photovoltaic systems. Photovoltaic systems are used to transform solar radiation into electrical energy, which can be self-consumed or fed into the grid.
TheECO-DC-INV-AC also maintains the same number of inputs as outputs, for the new multi-MPP inverters, and the individual protections of 1000Vdc fuse holders and Vdc surge protectors. Inputs are via MC4 connectors (optional).
In addition we protect the AC side with a Type A differential protection, a circuit breakerand a Vac Type 2 transient overvoltage protection with its protection
partner.
The protectors incorporated in the ECO-DC-INV-AChave been developed to protect against discharges and surges caused by lightning strikes on the DC side of these systems. The protection consists of three stages of varistors equipped with thermal disconnectors that indicate through a window the failure of the element. It has a remote output (indication contact).
