Siemens Contactor, 6kV Main Circuit Surge Voltage Resistance, DIN Rail Mounting - SIRIUS Series - 3RT2035-1KB40


When you're on the lookout for a safe circuit-switching device, opt for this contactor from Siemens. It makes and breaks power circuits and has an 18.5kW rating, so handles demanding loads. Fast-acting contacts minimise the risk of equipment damage from electrical arcs. As it delivers up to 10 million switching cycles, you can rely on the unit's longevity. Your circuit is protected against power surges of up to 6kV, thanks to its integrated varistor. This contactor is specifically designed to switch large current circuits like ones that power industrial motors and commercial lighting systems.

Features & Benefits


• Screws or snaps onto a standard 35mm DIN rail for easy assembly
• Space-saving dimensions of 114 (H) x 55 (W) x 130mm (D) to maximise board packing space
• IP20 rating indicates it has a finger-safe front face for protection against electric shocks
• Light environmental footprint as it's end-of-life optimised with a minimal landfill rate of 10%

How do I wire this contactor?


The device has straightforward screw terminals, so you can wire it using only a screwdriver. These connections are durable and call for minimal maintenance – even in vibrating conditions.
