SIRIUS 3RT1023-1BB40-ZW95 — 24 VDC Power Contactor, Size S0
Its 24 VDC coil draws 5.4 W holding power, and the contactor is rated for AC-3 duty at 4.5 kW at 500 V and 5.5 kW at 690 V — covering common 400 V and 690 V three-phase motor circuits across Europe and export markets. The coil's pick-up and hold power are identical at 5.4 W DC, which simplifies the DC supply sizing — no inrush surge beyond the steady-state draw. Rated operational current at AC-12 (resistive load) is 10 A maximum, while the AC-4 (plugging/reversing) rating is 8.5 A at 400 V — useful for high-duty-cycle applications like hoists or reversing conveyors where the contactor makes and breaks stalled-rotor current.
Short-circuit protection coordination is specified for both Type 1 and Type 2. This lets the panel builder choose between tighter protection and higher fault-clearing capacity based on the application's risk profile.
Main current circuit terminals are screw-type, accepting solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and up to 2x (0.75 to 4 mm²). For stranded conductors, the range is 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²), with a maximum of 2x 10 mm². AWG equivalents for main contacts are 2x (16 to 12), 2x (14 to 10), and 1x 8. This covers most panel wiring from control circuits up to moderate motor power feeds.
