Siemens 3RT1316-1BB40 4-Pole Contactor (24V DC Coil)
Siemens 3RT1316-1BB40 4-pole Contactor for AC-1 duty.
The Siemens 3RT1316-1BB40 is a 4-pole contactor designed for AC-1 applications with a rating of 18A and 12 kW at 400V AC. It operates with a 24V DC coil voltage and features 4 normally open (NO) contacts, making it suitable for switching resistive loads or distributing power. This specific model uses screw terminals for connection. Please note that this product is phased out, with the successor being the SIRIUS 3RT2 series, specifically the 3RT2316-1BB40.
This contactor is typically used for switching non-inductive loads such as lighting circuits, heating elements, or general power distribution in control panels. Its 4-pole configuration is beneficial when all poles need to be switched simultaneously for complete isolation or load distribution.
Stanlo Automation, a veteran-owned distributor of industrial surplus parts, offers the Siemens 3RT1316-1BB40. While this part is phased out, we may have available stock. Sourcing from Stanlo can help you maintain existing equipment or find suitable replacements for your automation needs.
