Siemens Contactor, 2 Auxiliary Contacts, 690V Insulation Resistance - SIRIUS Innovation Series - 3RT2035-1NB30


Bring your low-voltage circuits to life with this contactor from Siemens. It controls the opening and closing of your electrical feed, so automatically ensures devices are powered when needed. A built-in varistor provides over-voltage protection by clamping down on transient surges. As the unit is insulated, you can handle it safely without risking an electric shock. A typical mechanical service life of up to 10 million cycles means it keeps up with even the fastest applications. Choose a contactor like this to switch current to the electric motors or load feeders found in industrial power supplies and lighting systems.

Features & Benefits


• Wide operating temperature range between -25°C and +60°C, for compatibility with demanding settings
• Screw terminals hold conductors securely to cut out time spent on re-tightening
• Suitable to use with both AC and DC power supplies, for wide compatibility
• Reacts speedily, with a marginal opening delay time between 35 and 55ms

Can I mount two contactors in this range side by side?


Yes, the modular SIRIUS range is designed to optimise packing efficiency, so you can mount two units side by side with zero spacing in between.
