The Siemens 3RT2316-1BF40 is a genuine Siemens SIRIUS 3RT23 four-pole contactor designed for reliable switching and control of electrical loads in industrial automation and control applications. It is rated at 18 A in AC-1 utilization category at 400 V and 40°C, making it suitable for switching non-inductive and low-inductive loads.
This Siemens contactor features a 110 V DC control coil and uses screw terminals for electrical connections. Its compact Size S00 construction makes it suitable for installation in industrial control cabinets, automation panels and electrical switching systems where space-efficient and dependable switching is required.
The 3RT2316-1BF40 has a 4-pole main circuit with 4 normally open main contacts. The contactor is equipped with an auxiliary switch for control, signaling and interlocking functions. Siemens specifies an AC-3 rating of 9 A at 400 V and an AC-4 rating of 8.5 A at 400 V, allowing selection for appropriate motor-switching applications based on the actual load and utilization category.
The contactor provides a 690 V rated insulation voltage for the main and auxiliary/control circuits and a 6 kV surge withstand voltage. Siemens specifies an operating ambient temperature range of -25°C to +60°C and a typical mechanical service life of up to 30 million switching cycles.
