Sup2 500v 20ka-40ka 2pole

The "Sup2" refers to the manufacturer or brand of the switch. "500V" indicates the maximum voltage rating of the switch, which means it is designed to handle a maximum voltage of 500 volts.

The "20KA-40kA" rating indicates the short-circuit current rating of the switch, which means it is designed to safely interrupt or switch the circuit in the event of a short-circuit with a current between 20,000 and 40,000 amperes.

"2Pole" indicates that the switch has two poles, which means it can control the flow of electricity to two separate circuits simultaneously.

The Sup2 500V 20KA-40kA 2Pole is an electrical switch with a maximum voltage rating of 500 volts, a short-circuit current rating between 20,000 and 40,000 amperes, and a two-pole design, typically used to control the flow of electricity in a circuit with two separate branches.

Description

DC500V 20KA-40KA 2 pole dc surge protection device The SUP series Surge Protection are designed to protect against lightning surge voltages in photovoltaic power supply networks. These units must be installed in parallel on the DC networks to be protected and provide common and differential modes protection. The SUP series is available for the main operating voltages in photovoltaic: 1000 Vdc. The use of SUP series Surge Protection is recommended at both ends of the DC power supply line (solar panel side and inverter/converter side), Especially if the line routing is external and long. The electrical diagram of the SUP series is based on high energy PV equipped with specific thermal disconnectors and related failure indicators. The SUP series is made with plug-in modules to allow a fast and easy maintenance in case of failure (disconnection from the DC network). capacity 3 modules DIN 43880
