Product Positioning

The Siemens SIRIUS 3RB3026-1NB0 is an S0-size solid-state electronic overload relay with a current setting range of 0.32~1.25A and 10 tripping levels, making it suitable for overload protection needs in small motor circuits.

Core Product Advantages and Features

Electronic precision jump

By replacing the traditional bimetallic strip with electronic circuitry, the ejection action is precise and repeatable, reducing the chance of false ejection.

S0 size direct installation

It can be directly installed above an S0 size contactor, eliminating the need for additional wiring and reducing panel space requirements.

Phase loss and imbalance protection

It has a phase loss detection function, which can immediately disconnect the circuit when a single phase of the motor is abnormal, so as to avoid burnout.

Manual/Automatic Reset Switch

After disconnection, manual or automatic reset can be selected according to on-site needs, offering high operational flexibility.
