Description

3KE4430-0BA SIEMENS Switch Disconnector

Product Dimensions：

The Siemens 3KE4430-0BA is a 3-pole switch disconnector designed for isolating electrical loads. It typically features a front-mounted rotary operator with a black handle, allowing for manual switching and clear indication of its ON/OFF (connected/disconnected) status.

Product Details

• Type: Switch Disconnector
• Poles: 3-pole
• Operating Mechanism: Front-mounted rotary operator with a black handle. This design allows for manual control and clear visual indication of the switch position.
• Function: Primarily used to disconnect a circuit from its power source, providing a visible air gap for safe maintenance or repair work. It is not designed for breaking short-circuit currents.

Product Parameters

• Rated Current (Ie​): $630\text{ A}$
• Rated Operating Voltage (Ue​): $690\text{ V AC}$ (also capable of handling DC, e.g., $440\text{ V DC}$ for some variants like 3KE4430-0GA which is very similar)
