SIEMENS 3RT2036-1SF30 Contactor

1. Product Name‌
SIEMENS 3RT2036-1SF30 Contactor

‌2. Product Brief Introduction‌
The SIEMENS 3RT2036-1SF30 is a magnetic contactor from Siemens' proven SIRIUS 3RT line. It serves as a robust electromechanical switch designed for remote and automatic control of high-power electrical loads, particularly for starting and stopping motors efficiently and reliably.

‌3. Product Description‌
The SIEMENS 3RT2036-1SF30 is a high-performance, three-pole magnetic contactor, part of the renowned Siemens SIRIUS modular system. Engineered for industrial control applications, it acts as a remote-controlled switch capable of handling substantial electrical currents. Its primary function in a system is to establish and interrupt the main power circuit to an electrical load, most notably a ‌SIEMENS MOTOR‌. Designed for durability, the contactor features a rugged construction with silver alloy contacts that minimize arc erosion, ensuring a long mechanical and electrical service life even under frequent operation. It incorporates a magnetic coil system that, when energized by a low-voltage control signal (typically 24V DC or various AC voltages), pulls in the main contacts to power the connected ‌SIEMENS MOTOR‌. Built for versatile integration, the 3RT2036-1SF30 is designed for easy mounting, offers reliable performance in various ambient temperatures, and features a modular design that often allows the addition of auxiliary contacts, timer modules, and surge suppressors. This makes it a fundamental component in motor control centers (MCCs), machinery panels, and automation systems, providing a safe and reliable means to control the primary power to ‌SIEMENS MOTORs‌ in applications ranging from pumps and fans to conveyors and compressors.
