Siemens 5TT5043-0 is a robust 4-pole power contactor engineered for demanding motor control tasks in industrial and commercial environments. With a 220V AC/DC coil voltage, this contactor enables flexible operation across varied supply conditions. The high contact current rating of 40A makes it suitable for switching heavy electrical loads, including motors and lamp loads at different phase positions.
Designed with four normally closed auxiliary contacts and screw terminal connections, this contactor ensures secure integration with control circuits. The control circuit voltage is rated at 230V, enabling seamless coordination with common industrial control systems.
The 5TT5043-0 model delivers efficient motor control functionality, meeting requirements of EN 60947 and UL 508 standards for quality and performance. It is optimized for on/off switching of both single-phase and three-phase motors and can be used to control lamp loads, striving for symmetrical phase distribution.
Engineered for durability, the contactor operates within a broad ambient temperature range from -15°C up to 55°C. The compact product dimensions - 53.5mm length, 90mm width, 70.7mm depth - make it suitable for modern control panels where space efficiency is critical.
Applications include motor control, infrastructure automation, and industrial switching in electrical distribution panels. The Siemens contactor’s O/I automatic function allows testing via manual switch without applying a control voltage, and the switching position indicator helps operators recognize operating states efficiently.
Heavy-duty performance for industrial motors, pumps, HVAC panels, and lighting distribution. Supports AC/DC coil voltages for adaptability in automation and control. Reliable switching for symmetrical load management across multiple phases.
Screw terminals for straightforward installation and wiring integrity. Used in water treatment plants, manufacturing facilities, and commercial automation systems. Explore the broad range of Siemens Power Contactors and automation control equipment in the EnvMart electronics and industrial automation category.
