- Description
For two-pole isolation at up to 440 V AC, ABB offers the SD202/25 (SKU 2CDD282101R0025), a 25 A DIN-rail switch disconnector built on the same SD200 platform as its single-pole counterpart. Its two modules house two NO contacts with ON/OFF position indication and a 25 kA conditional short-circuit rating, so it isolates both poles of a two-wire circuit with a single toggle.

Selection Notes
The SD202/25's two poles switch both conductors of a two-wire circuit simultaneously, which matters where local codes or equipment require double-pole isolation rather than single-pole switching. At 440 V AC and In 25 A, it fits lighter two-pole loads; heavier ones fit the 32 A version in the same 2-module frame. Like all SD200-series disconnectors, it isolates but does not interrupt fault current, so it belongs upstream of a fuse or breaker, not in place of one.
