The Siemens 3RT2024-1BB40 is a robust and reliable SIRIUS series contactor for industrial motor control and power switching applications. Engineered to handle up to 5.5 kW at 400V in AC-3 applications, this 3-pole contactor ensures efficient switching performance with minimal power loss. Operating at 24V DC, it features one normally open (NO) and one normally closed (NC) auxiliary contact, making it versatile for various automation and control tasks. The IP20-rated protection, screw-type terminals, and compact S0 size allow easy integration into control panels and electrical enclosures.
The Siemens 3RT2024-1BB40 is built for durability and efficiency. Its rated insulation voltage of 690V offers excellent protection against electrical faults. Its mechanical lifespan of 10 million operations ensures long-term reliability in demanding industrial environments. Additionally, its pollution degree of 3 allows safe operation in environments with moderate dust and moisture levels.
This contactor provides outstanding short-circuit protection, supporting fuse links up to 63A for type 1 coordination and 25A for type 2 coordination. It can handle up to 40A at AC-1 and 12A at AC-3 and AC-4 applications, making it ideal for switching motors and other electrical loads.
The control circuit operates at 24V DC, with a pull-in and holding power of 5.9W. The closing delay ranges between 50 to 170ms, while the opening delay is 15 to 17.5ms, ensuring responsive and precise switching. The auxiliary contacts are designed for high reliability, with a failure rate of only one faulty switching per 100 million operations at 17V and 1mA. These contacts can handle up to 10A at AC-15 (230V) and 3A at AC-15 (400V), providing flexibility for control circuit integration.
Designed for industrial environments, the Siemens 3RT2024-1BB40 can operate within a temperature range of -25°C to +60°C, with a storage capability of -55°C to +80°C. It withstands shock forces of up to 15g at 5ms and operates at altitudes up to 2,000m above sea level. The compact dimensions (45mm width, 85mm height, 107mm depth) allow for efficient panel installation, and the screw and snap-on mounting options enable flexible positioning.
The screw-type terminals support solid and stranded conductors, making installation straightforward. The primary contacts accommodate conductors from 1mm² to 10mm², while the auxiliary contacts support conductors from 0.5mm² to 2.5mm². The contactor can be installed side by side with no spacing requirements, making it ideal for space-constrained applications.
The Siemens 3RT2024-1BB40 comes with a 2-year MRO Electric and Supply warranty and is eligible for free shipping, ensuring cost-effective procurement and long-term peace of mind.
