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
• IP20 rating when used with a cover means it's touch-proof and protected against objects larger than 12mm

Siemens 3RN1 Thermistor Relays
3RN1 thermistor relays are a range of thermal protection devices, which when used in conjunction with external PTC thermistors, offer temperature monitoring of electrical drives, transformers and other critical components such as bearings. The 3RN1 range operates on the principle of closed-circuit current and are therefore self monitoring in the event of sensor wire breakage.
