Key Features:

• Motor Rating: The 3RT1025-1BB40 is rated for a motor power of 7.5 kW at 400 V AC. This makes it suitable for controlling mid-range motor sizes in industrial applications.

• Current Rating: It has a current rating of 17 Amps, capable of handling standard motor currents within this range without overheating or damage.

• Poles: The contactor is a 3-pole device, designed for three-phase systems, which are common in industrial motor applications.

• Normally Open Contacts: The device features 3 Normally Open (NO) contacts, typically used to close the circuit when the contactor is energized, allowing the motor to start.

• Coil Voltage: The coil voltage for this contactor is 24 VDC, making it compatible with low-voltage DC control circuits.

• Voltage Rating: Rated for use in circuits up to 600 VAC, it offers flexibility for use in both low- and high-voltage applications.

• Size: The S0 size refers to the physical size of the contactor, which is a standard size used in industrial controls.

• Terminal Type: The contactor has screw terminals, which provide secure and reliable connections for the wiring.

• Ingress Protection: With an IP20 rating, the device is protected against the ingress of solid objects larger than 12 mm, but it is not designed for water resistance. This makes it suitable for dry, industrial environments.

• Successor Model: The successor to the 3RT1025-1BB40 is the Siemens 3RT2025-1BB40, which may offer improved features or updated specifications.
