This is a Siemens SIRIUS power contactor designed for switching electrical loads in industrial control panels, particularly three-phase motor and power circuits.
It is commonly used for motor control, load switching, pump and fan control, conveyor systems, machine panels, and other industrial automation applications that require reliable switching of three-phase circuits.
The control coil is rated for 24 V AC at 50 Hz. This means the contactor is intended to be energized by a 24 V AC control circuit.
The contactor has 3 main poles, making it suitable for switching three-phase electrical loads.
This unit is Siemens size S0, a compact contactor frame size commonly used in industrial motor control assemblies.
The AC-3 operating current rating at 400 V is 9 A. AC-3 ratings are typically used when selecting contactors for squirrel-cage motor starting and switching duties.
The AC-3 operating power rating at 400 V is 4 kW, making the 3RT1023-1AB00 suitable for appropriately rated motor switching applications.
The AC-1 current rating is 40 A at 400 V with an ambient temperature of 40 °C. At up to 690 V, it is rated 40 A at 40 °C and 35 A at 60 °C.
The AC-1 operating power rating at 400 V is 23 kW. AC-1 ratings are generally associated with non-inductive or slightly inductive loads.
The base configuration listed for this contactor has no built-in instantaneous auxiliary NO or NC contacts. Auxiliary contact blocks may be used where compatible with the installation requirements.
It uses screw-type terminals for both the main current circuit and the auxiliary/control circuit connections.
The contactor can be screw mounted or snapped onto a 35 mm standard mounting rail according to DIN EN 50022.
The contactor measures approximately 85 mm high, 45 mm wide, and 91 mm deep.
The operating ambient temperature range is -25 °C to +60 °C, subject to the electrical ratings and installation conditions.
The typical mechanical service life of the contactor is 10,000,000 switching cycles. With added electronics-compatible auxiliary switch blocks, the typical value is 5,000,000 switching cycles.
The front of the contactor is rated IP20, while the terminals are rated IP00. This should be considered when the unit is installed inside an enclosure.
For the main circuit, the specified gL/gG fuse rating is 63 A for coordination type 1 and 25 A for coordination type 2.
For the main contacts, the contactor accepts solid, single-stranded, or multi-stranded conductors in specified ranges up to a maximum of 2 x 10 mm². For AWG conductors, listed options include 2 x 16 to 12, 2 x 14 to 10, or 1 x 8.
The magnet coil has an apparent pick-up power of 61 VA and an apparent holding power of 7.8 VA at AC operation.
The coil terminals are marked A1 and A2. The main incoming terminals are marked 1/L1, 3/L2, and 5/L3, with corresponding outgoing terminals 2/T1, 4/T2, and 6/T3.
