Siemens 3RA2315-8XB30-1BB4 Reversing Contactor

The Siemens 3RA2315-8XB30-1BB4 is a 3‑pole reversing contactor with a 24 V DC coil designed for forward‑reverse motor control in industrial machinery. It is rated for AC-3e/AC-3 duty, handles up to 7 A and up to 3 kW at 400 V, and uses screw-terminal wiring with built‑in electrical and mechanical interlocks to prevent simultaneous energization of opposing directions. This unit is part of Siemens' Sirius family of contactors, offering a compact three‑phase switching solution suitable for motors in conveyors, machine tools, pumps, and fans where direction reversal is required. The coil voltage is 24 V DC, enabling integration with standard low‑voltage control circuits and reliable operation in demanding environments.
