Siemens SIRIUS 3RT1015-1AP62 Power Contactor
The Siemens 3RT1015-1AP62 is a compact, industrial-grade 3-pole power contactor from the trusted SIRIUS modular system collection. Engineered for exceptional switching reliability in automation, motor control, and electrical plant machinery, this size S00 contactor is rated for switching standard 3-phase motors up to 3 kW at 400V (AC-3 utilization category). Equipped with a 220V AC (50Hz) / 240V AC (60Hz) control coil and a built-in Normally Closed (1 NC) auxiliary contact, it offers a space-saving footprint without compromising on heavy-duty cyclic durability.
Key Features
-
SIRIUS Modular System Compatibility: Integrates seamlessly into the Siemens modular ecosystem, making it effortless to attach function modules, surge suppressors, or thermal overload relays.
-
Optimized Motor Switching (AC-3): Expertly configured to handle the high inrush currents of three-phase squirrel-cage motors up to 7A / 3 kW at standard 400V line loads.
-
Dual-Frequency Control Coil: Features a versatile AC control circuit winding designed to operate cleanly at 220V AC on 50Hz or 240V AC on 60Hz systems.
-
Integrated Auxiliary Contact: Outfitted with 1 NC (Normally Closed) built-in auxiliary path, providing immediate hardware feedback for status loops or safe cross-interlocking configurations.
-
Rugged, Finger-Safe Terminals: Built with robust screw clamping terminals rated at IP20 touch protection to prevent accidental technician contact during installation or manual override tests.
