The Siemens SIRIUS S2 size contactor and overload relay terminal cover are also compatible with the 3RW403 soft starter. The dimensions are approximately 55×22.5×40.2mm. It is installed above the terminal block to enhance protection and reduce the risk of accidental contact with metal terminals. It is suitable for use in panel maintenance and repair projects.

3RT1936-1TR00

The Siemens SIRIUS S2 and S3 size contactor diode surge suppression assembly is designed for DC 24V coil circuits. It does not include an LED indicator and is installed at the bottom of the contactor. It can absorb back EMF surges when the coil is de-energized, protecting nearby relays and electronic components for safe operation.

3RT1936-1CD00

The Siemens SIRIUS S2 and S3 size contactor uses an RC surge absorber, which is compatible with AC 127 to 240V or DC 150 to 240V coil circuits. It is installed on the contactor coil terminals and can reduce the interference and impact of surges on surrounding control components during power failure.
