2P DC 450V 20-40KA Solar PV Surge protective device

A surge protective device (SPD) is a device designed to protect electrical equipment and systems from voltage surges or transient overvoltages. It is commonly referred to as a surge protector or a lightning arrester. The specifications you provided, “450V 2P,” indicate the voltage rating and configuration of the surge protective device. Here’s what these specifications mean:

1. Voltage Rating: The surge protective device is designed to handle voltage surges up to 450 volts. This means it can protect against transient overvoltages that occur within that voltage range.
2. 2P: The “2P” refers to the configuration of the device. The “P” stands for “pole,” and in this case, “2P” indicates that the surge protective device has two poles. This typically means that it is designed to be connected in a two-pole circuit configuration, providing protection for both the live and neutral conductors.
