Product Description
Siemens 3RH2422-1BM40 is a high-performance 3RH2 series contactor relay featuring a 220V dc coil and a contact current rating of 10 A. This contactor relay is designed for precision switching applications in industrial and automation environments. With a configuration of 2 normally open (NO) and 2 normally closed (NC) contacts, it provides versatile control options suitable for a broad range of use cases.
It is designed for straight function operation and can be seamlessly mounted on DIN rails for easy integration into control panels and automation cabinets. The contactor supports control circuit voltages at 220V dc and contact voltages of 600 V dc and 690 V ac, making it suitable for demanding electrical control scenarios.
Engineered to operate reliably in harsh industrial environments, it withstands temperatures from -25°C up to 60°C. The device's screw terminal connections ensure robust and secure electrical contacts, suitable for repeated operations.
Compliant with key international standards such as IEC 60947-1, IEC 60947-5-1, UL, and CSA, this contactor relay delivers high safety and performance reliability. Its high degree of contact stability at low voltages and currents allows integration with solid-state circuits drawing currents as low as 1 mA at voltages above 17 V.
Compact dimensions of 90 mm length, 73 mm width, and 57.5 mm depth allow for optimized usage of panel space. This Contactor Relay was manufactured in Germany ensuring premium build quality and durability expected in advanced industrial automation systems.
Equipped with 2 NO/2 NC contacts for flexible switching configurations. Suitable for industrial, automation, manufacturing, and electrical control applications. Climate-proof and finger safe for enhanced operator safety.
Supports expansion up to four contacts via snap-on auxiliary switch blocks. Noise suppression options via RC elements, varistors, or diode assemblies compatible for coil protection. Used widely in construction, HVAC, water treatment, and manufacturing control systems.
