At 55 °C it holds 158 A, at 60 °C 155 A, at 65 °C 153 A, and at 70 °C 150 A. This is a pure disconnector — no overload or short-circuit protection inside. It isolates the load for safe maintenance or switching. It carries two auxiliary switches HP (high-performance) with 2 CO contacts. The main current circuit connects via busbar connection with front terminals. That's a panel-builder detail: you land busbars on the front face, not the back or sides, which simplifies busbar routing in a distribution board.
Mechanical service life is 15 000 operating cycles typical. That's adequate for a disconnector used for infrequent isolation; not for daily switching duty. Maximum power loss is 38 W at full load — factor that into panel thermal calculations if the cabinet is tightly packed. That covers cold storage and freezer environments — runs cold and stays cold down to -25 °C operating.
