NEW ARRIVAL: Siemens SIRIUS 3RT2026-1AD04 Power Contactor Now in Stock
Model Description
We are pleased to announce the immediate availability of the Siemens SIRIUS 3RT2026-1AD04 power contactor, a robust switching solution for industrial motor control applications. This three-pole AC-3 rated contactor handles currents up to 25 A with an 11 kW motor rating at 400V AC, making it ideal for controlling medium-power asynchronous motors. The unit features a 42V AC 50Hz coil voltage for specific control circuit requirements and includes 2 normally open (NO) plus 2 normally closed (NC) auxiliary contacts for comprehensive control logic integration. Built in compact S0 size, the device utilizes reliable screw terminals for secure wiring connections and supports conductor cross-sections from 0.5 to 2.5 mm². The removable auxiliary contact block design allows for easy maintenance and field configuration changes without complete unit replacement.
Key Features
The 3RT2026-1AD04 delivers exceptional performance across demanding industrial environments. With an insulation voltage rating of 690V and impulse withstand voltage of 6 kV, it ensures reliable operation in challenging electrical conditions. The contactor exhibits minimal power loss of only 4W during operation, contributing to energy efficiency in control panels. Mechanical durability exceeds 10 million operating cycles, while electrical endurance reaches 1.2 million cycles at AC-3 utilization category. Operating temperature range spans -25°C to +60°C, with storage capability from -55°C to +80°C. The device meets IEC 60947-4-1 and EN 60947-4-1 standards, with certifications including CE, cULus, and CCC markings.
