Siemens Overload Relay, 3 Poles, 1kV AC Voltage Rating - SIRIUS Classic Series - 3RB2056-1FC2
To prevent high currents from damaging your setup, hand over electrical management to this overload relay from Siemens. It cuts power to your motor when current levels are too high, keeping equipment safe and sound. The unit packs a punch thanks to its current rating of 200A, which makes it compatible with heavy-duty machinery. As it's a solid-state relay, there are no moving parts, meaning there's minimal risk of wear and tear. The screw terminals make it a cinch to wire up using a simple screwdriver. You'll find this type of relay used in heating and cooling applications.
• Surge voltage resistance rating of 8kV for protection against electrical hazards
• IP20 rating when used with a cover means it's touch-proof and protected against objects larger than 12mm
• Manual and automatic reset functions help you quickly restart your equipment
• Wide operating temperature range between -25°C and +60°C for use in harsh conditions
