Schneider Electric XB5AJ21 selector switch 22 mm 2 position black

Schneider Electric XB5AJ21 Selector Switch

The Schneider Electric XB5AJ21 is a 22 mm industrial selector switch designed for panel mounting in control systems. It features a maintained two-position action with an extended lever operator and a single normally open contact block rated for 10 A at 600 V AC. The black plastic bezel and head provide IP67, IP69 and IP69K ingress protection alongside NEMA 1, 2, 3, 4, 4X, 12 and 13 ratings. This component suits original equipment manufacturers and maintenance teams building or servicing industrial machinery.

Suitable Applications and Limitations

This switch suits panels requiring a 22 mm cut-out and a maintained two-position selector with high environmental sealing. It is not suited for applications needing momentary action, key-operated security, illuminated status indication or a different contact configuration such as normally closed or multiple poles. Buyers who need a selector with a cam mechanism, key removal options or a shorter flush operator should look at alternative series. Operators requiring a different voltage or current rating must verify compatibility separately.

Decisive Specification

The contact rating of 10 A at 600 V AC with NEMA B600/Q600 designation determines whether this switch can handle the intended control circuit load. Verify that the application voltage and current stay within this rating before installation. The maintained two-position operation and IP69K sealing are fixed characteristics that cannot be changed in the field.
