3RT1016-1AK61

The 3RT1016-1AK61 power contactor from Siemens, within the SIRIUS series, serves a critical role in managing electrical loads. This contactor is configured with three poles and operates as a non-reversing device. It provides a rated operating current in the range of 9 to 22 amperes, accommodating various power requirements. The control supply voltage ranges from 110 to 120 volts AC, making it adaptable to common circuit designs.

Rated for 50 to 60 Hertz, this contactor performs efficiently across standard supply frequencies. The electrical connections are made through screw-type terminals, forming secure integration into existing systems. Additionally, installation is streamlined via DIN rail mounting, enabling quick and reliable assembly.

Protection class IP20 ensures that it remains effective in safe environments, while its operating temperature range of -25°C to 60°C allows it to perform reliably in both cold and warm conditions as long as the environment remains non-condensing. It also boasts a substantial mechanical lifespan, rated at 30,000,000 operational cycles, indicative of its durability under continuous use.

The maximum installation altitude for this model is permissible up to an impressive 2,000 meters above sea level. This makes it suitable for use in elevated locations where electrical systems are required. The design includes three main normally open contacts, supplemented by one auxiliary normally open contact, allowing for versatile control applications.
