Siemens 3RT2015-2JB41 Contactor

Siemens 3RT2015-2JB41 is a three-pole power contactor in the S00 frame, designed for AC-3e/AC-3 motor control with a 24 V DC coil. It switches up to 7 A, equivalent to about 3 kW at 400 V, and includes a built-in diode for coil suppression. The device provides one normally open auxiliary contact for signaling or interlock purposes, and wiring is via spring-loaded terminals for reliable connections. Coil voltage tolerance is 0.7 to 1.25 times the nominal 24 V DC, accommodating typical supply variations. This model is not expandable with an auxiliary contact block, making it a compact, dedicated control device suited for PLC-driven automation panels where space is at a premium and reliable AC-3 motor switching is needed. In practical terms, it serves as a compact interface to switch small three-phase motors or similar AC loads from control logic, while offering a straightforward, single-No signaling path and a diode-protected coil for robust operation.
