The Siemens 3RT2025-2BB40 is a robust power contactor designed to handle a variety of applications within industrial environments. This three-pole contactor is engineered to control motors and is capable of switching power circuits up to AC-3, 17 A, and 7.5 kW at 400 V ac. It features a 24 V dc coil and includes both one normally open (NO) and one normally closed (NC) auxiliary contact for added flexibility in circuit design.
Constructed with a size S0 frame, the 3RT2025-2BB40 is compact and suitable for space-saving installations. It utilises spring-loaded terminals, ensuring a secure and maintenance-free electrical connection that is both time-efficient and reliable for system integrators and electricians.
The contactor is designed with safety in mind, boasting a finger-safe protection class of IP20, which helps to prevent accidental contact with live components. It also has a high degree of pollution resistance, rated at level 3, and can withstand impulse voltages up to 6 kV, ensuring durability and reliability in harsh industrial settings.
With an insulation voltage rated at 690 V, the 3RT2025-2BB40 is suitable for a wide range of applications, including but not limited to motor control centres, conveyor systems, and HVAC installations. Its mechanical service life is impressive, offering a typical expectancy of 10 million switching cycles, which speaks to the longevity and quality of Siemens engineering.
The contactor's ambient operating temperature range of -25 to +60 °C and storage temperature range of -55 to +80 °C make it versatile for use in various environmental conditions, and it can be installed at altitudes up to 2,000 metres above sea level without derating.
Overall, the Siemens 3RT2025-2BB40 power contactor is a reliable and efficient solution for controlling motors and power circuits in industrial applications, providing both performance and safety in a compact design.
