Photovoltaic DC combiner box TWDX

Product selection

Product Overview

The DC box series is mainly used in circuits with AC 50Hz, rated voltage 400V, and rated current up to 3150A.

Used for infrequent connection and disconnection of circuits and electrical isolation. The acceleration mechanism with instantaneous release of spring energy storage achieves fast connection or disconnection (13.8 meters per second), independent of the speed of the operating handle, greatly improving the ability to extinguish arcs. The shell made of glass fiber reinforced unsaturated polyester resin has good flame retardant performance, dielectric performance, carbonization resistance, and impact resistance.

Parallel double break point contacts have self-cleaning effects. All contacts have two separate contact surfaces.
