Product details

Siemens 3RT2517-1BM40 SIRIUS Contactor — Size S00, Screw Terminals, DIN Rail Mount

The main current circuit and magnet coil both terminate at screw-type terminals, making it a straightforward replacement for existing wired installations.

Side-by-side mounting is supported, with a required clearance of 6 mm at the side. No clearance needed upwards, forwards, backwards, or downwards.

The lifecycle stage is current production, per the manufacturer's status.

Terminal Specifications

Solid or stranded conductors accepted: 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), 2x 4 mm². Both the main current circuit and the magnet coil use screw-type terminals.
