Product description

The Siemens 3SB3400-0E is a contact block designed with two Normally Closed (NC) contact elements. It is intended for front plate mounting and uses screw terminals for secure electrical connections. This component belongs to the Siemens 3SB3 series, which is now phased out, with the SIRIUS ACT 3SU1 series serving as its successor.
