3RA2814-2FW10

Description

Overview

The Siemens 3RA2814-2FW10 is a high-performance solid-state time-delayed auxiliary switch designed for precision and reliability in industrial automation. Featuring off-delay functionality with a control signal, it provides versatile timing options for your electrical circuits. Equipped with 1 NC + 1 NO relay, this device operates across a broad time range of 0.05–100 seconds and supports 24-240 V AC/DC at 50/60 Hz. The integrated varistor efficiently attenuates contactor coil surges, while spring-loaded terminals ensure secure and easy installation. Designed to snap directly onto 3RT20 contactors and 3RH2 contactor relays, this switch is ideal for enhancing the safety and efficiency of your control systems.
