Siemens 3SB3400-0BA Contact Block - 1 NO Gold Contacts

The Siemens 3SB3400-0BA is a contact block featuring a single Normally Open (NO) contact with gold-plated contacts. It is designed for front plate mounting and uses screw terminals for connection. This part is from the Siemens 3SB3 series, which is phased out, and the SIRIUS ACT 3SU1 series is its successor.

The gold-plated contacts provide enhanced reliability and performance, especially in low-current or low-voltage applications where contact resistance can be critical. This makes it suitable for sensitive control circuits, micro-switching applications, and environments where corrosive elements might affect standard contacts.

Stanlo Automation, a veteran-owned surplus parts distributor, provides access to the Siemens 3SB3400-0BA contact block. For systems requiring the specific advantages of gold-plated contacts or continuing to use the 3SB3 series, Stanlo Automation is a reliable source for these specialized components. We ensure availability of critical industrial automation parts.
