Siemens SIRIUS Classic Overload Relay, 250kW, 4A - 3RB Series - 3RB2066-1MC2


Protect your industrial motors from overheating due to overload with this robust relay from Siemens' SIRIUS Classic range. It functions as part of the motor starter and works by monitoring the current flowing in the circuit. When the current rises, it'll trip above a set limit over a period of time and cut off power to the motor, protecting it from damage. This overload relay has a test function, so you can easily check that it's in good working condition. Manual and automatic reset options enable a quick restart after it's tripped. You can easily connect cables to this relay thanks to its screw terminals, which make installation quick and efficient.

• Power rating of 250kW for heavy-duty industrial use

• Broad operating temperature range of -25°C to +60°C for use in demanding environments

• Thermoplastic housing material is durable and impact resistant

• Light weight of 1.8kg for easy handling

How do I maintain this overload relay?


Maintain this relay by carrying out regular cleaning and rust removal. It's also important to check and tighten any loose screws to avoid heat accumulation from partial contacts. Frequent testing with a simulated overload current will flag up any performance issues.
