Siemens Contactor Relay, 24V DC Coil Voltage, 10A - SIRIUS Innovation Series - 3RH2122-1BB40
Safely turn an electric motor on and off using this contactor relay from Siemens. It has a high contact voltage rating of 690V AC (alternating current), so it's suitable for use with heavy-duty equipment. For additional signalling capabilities, you can attach two auxiliary switches to it. An integrated fuse link prevents damage in the event of a short circuit for enhanced electrical safety. A broad operating temperature range of -25°C to +60°C makes it suitable for use in demanding environments. Use this contactor to control high-current motors and lighting systems.
• Surge voltage resistance of 6kV to withstand overloads
• Contact reliability of one faulty switching operation per 100 million for dependable use
• Robust mechanical service life of 30 million switching cycles for long-lasting performance
• IP20 (ingress protection) rating means it's touch-proof and protected against objects larger than 12mm in size
How do I mount this contactor?
You can install this contactor on a standard 35mm mounting rail using screws or snap-on clips. It rotates up to 180° on a vertical surface for enhanced flexibility.
