Siemens 3LD2418-1TL13 Emergency Switching Device is a four-pole switch disconnector with an emergency-off function in the SENTRON family, designed to provide a robust safety isolation point in mains circuits. It is rated for Iu = 250 A and 400 V AC (AC-23), delivering up to 132 kW of service power at 400 V, making it suitable for high-demand safety interlocks on industrial equipment. The unit is intended for floor mounting with door coupling and uses a knob-operated mechanism with a red/yellow actuator, offering four-hole front mounting for the handle to ensure secure installation. This emergency switching-off device supports applications in safety circuits for machinery, control panels, and distribution boards where a reliable, manually actuated disconnect is required. Its rugged, compact design is optimized for environments where quick, unequivocal isolation is essential to protect personnel and equipment during maintenance or fault conditions.
