Product Details
Siemens Contactor Relay, 24V DC Coil Voltage, 10A - SIRIUS Innovation Series - 3RH2140-1BB40
Keep your electric motor running optimally with this contactor relay from Siemens. Its contact voltage rating of 690V AC (alternating current) means it's a good choice for high-powered motors. A surge voltage resistance of 6kV provides protection against overloads for enhanced safety. For simple and flexible installation, you can either screw it or snap it securely onto a standard 35mm mounting rail. Thanks to its robust mechanical lifespan of 30 million cycles, it's a long-lasting choice that won't need frequent replacement. Install this contactor relay to switch motorized industrial equipment on and off.
• Rotates up to 180° on vertical mounting surfaces for flexible assembly
• Wide operating temperature range of -25°C to +60°C for use in demanding environments
• Compact dimensions of 57.5 (height) x 45 (width) x 73mm (depth) for installation in areas with limited space
• Wide operating temperature range of -25°C to +60°C for use in demanding environments
