Siemens 3SB1400-2B Lamp Holder Contact Block Module is a front-plate mounted lamp holder accessory for Siemens 3SB2 pushbutton units, used to illuminate a panel indicator in control stations. It employs a BA9S lamp holder with an integrated resistor and screw-terminal connections, and it ships with a 130V lamp for 110/125V service. The module is designed for 130V operation, aligning with typical Siemens indicator lamp configurations in panel-mounted pushbutton assemblies.
