Overview

The Schlegel Elektrokontakt CT2_549 is a robust momentary switch designed for precise control in industrial automation and inverter applications. This component features a 3 mm travel distance, providing tactile feedback for reliable operation. The contact equipment consists of 2 normally open (NO) contacts, suitable for switching 2 x inverters. For superior conductivity and long-term reliability, the contacts are gold-plated with a 1.5 µm thickness. Connection is facilitated via Faston terminals measuring 2.8 x 0.8 mm, ensuring secure and efficient wiring. The CT2_549 adheres to Protection Class II, offering protective insulation for enhanced user safety. It operates without illumination and lacks labeling options, focusing on functional simplicity and cost-effectiveness. Key specifications include a rated insulation voltage (Ui) of 300V and a thermal continuous current (Ith) of 16A. For AC15 applications, it supports a rated operating voltage (Ue) of 240V and a rated operating current (Ie) of 3A. In DC13 applications, it handles 250V / 24V with a rated operating current (Ie) of 0.2A / 2A. The switch is built to withstand 1 million switching cycles under rated load. Manufactured in Germany (DE), the CT2_549 is a dependable choice for critical control circuits where consistent performance is paramount. Its compact design and reliable switching capabilities make it an ideal component for panel building, control cabinets, and machinery where accurate momentary actuation is required.
