Siemens 3RT2025-1BE40 SIRIUS 3RT2 Power Contactor, 60V DC, 17A, 7.5 kW, Size S0, Screw Terminal Original Brand New

Overview

The Siemens 3RT2025-1BE40 is a highly reliable 3-pole SIRIUS 3RT2 Power Contactor designed for switching motors in industrial applications. As part of the modular SIRIUS system, this Size S0 contactor offers convincing performance from a compact design with high contact reliability. It is rated for operation up to 17 A (AC-3e/AC-3) and 7.5 kW at 400 V. The unit is equipped with a 60 V DC operating coil and features integrated 1 Normally Open (NO) + 1 Normally Closed (NC) auxiliary contacts for control circuit integration. Connection to the main and auxiliary circuits is achieved via robust screw terminals. This model replaces the well-proven 3RT1 series.

Benefits & Functions
