3RT6024-1AN20 | Siemens Power Contactor

Description

Siemens 3RT6024-1AN20 is a 3-pole power contactor, size S0, with a rated operational current of 12 A at AC-3, 400 V (5.5 kW). This unit features an AC-operated solenoid coil at 220 V 50/60 Hz and includes integrated 1 NO + 1 NC auxiliary contacts with screw terminals. The device is finger-safe according to EN 50274 and maintains an IP20 protection class on the front. As a component of the SIRIUS modular system, it supports snap-on mounting onto 35 mm standard rails or screw fixing onto mounting plates. The technical specifications define a typical mechanical service life of 10 million operating cycles and a maximum operating frequency of 1,000 switching operations per hour at AC-3.
