It features an adjustable overload release (A-release) range of 10–16 A, a fixed short-circuit release (N-release) at 208 A, and Class 10 tripping characteristics. The unit uses spring-type (cage clamp) terminals for maintenance-free, vibration-resistant connections and belongs to the compact Size S00 frame.

The Siemens 6SL3210-1KE18-8AF1 is a compact SINAMICS G120C variable frequency drive designed for versatile industrial motor control. It is a three-phase drive rated at 4 kW (5 HP) for low overload applications, featuring an integrated Class A EMC filter and a PROFINET / EtherNet/IP fieldbus interface for seamless integration into modern automation networks . The G120C series is the modern replacement for the MICROMASTER 420, combining compact dimensions with the advanced control capabilities of the SINAMICS platform. Its integrated Safe Torque Off (STO) safety function eliminates the need for external safety components, while its energy-optimized vector control contributes to efficient operation in conveyor systems, pumps, fans, and compressors. 

The Siemens 6SL3255-0AA00-4JA2 is the Intelligent Operator Panel 2 (IOP-2) for the SINAMICS G series of frequency converters. It is a high-contrast color display panel that provides local commissioning, parameterization, diagnostics, and control of the drive directly from the cabinet door or the converter face. The IOP-2 is the advanced operator panel option for the SINAMICS G family, offering significantly more functionality than the basic BOP-2 panel. It features a graphical color display, multi-language support (including simplified Chinese), and advanced commissioning wizards that simplify both basic and complex drive setup. The panel is classified under PM300: Active Product lifecycle status, ensuring ongoing availability and support.

The Siemens 3RH2911-2FA22 is a front-mounting auxiliary switch block from the SIRIUS 3RH2 series, designed to expand the control circuit capacity of SIRIUS 3RT2 power contactors and 3RH2 contactor relays. It provides a 2 NO + 2 NC contact configuration with spring-loaded (cage clamp) terminals, enabling reliable signaling, interlocking, and status feedback in industrial control panels. This auxiliary switch is a current, active product (PLM status PM300: Active Product), ensuring long-term availability for new installations and maintenance alike . The spring-loaded terminals provide maintenance-free, vibration-resistant connections, while the front-mounting design allows the block to be installed without tools and independently of the contactor size.

The Siemens 3RH2921-1DA02 is a lateral-mounting auxiliary switch block from the SIRIUS 3RH2 series, designed to expand the control circuit capacity of SIRIUS 3RT2 power contactors and 3RH2 contactor relays. It provides 2 Normally Closed (NC) contacts with screw terminals, enabling reliable status feedback, interlocking, and signaling functions in industrial control panels. This auxiliary switch is a current, active product (PLM status PM300) and is the modern counterpart to the discontinued 3RH19 series, ensuring long-term availability for new installations and maintenance alike.

The Siemens 6SE6400-0BP00-0AA0 is the Basic Operator Panel (BOP) for the MICROMASTER 4 series of frequency inverters, including the MICROMASTER 420 and 440. It provides a simple, direct interface for reading and modifying drive parameters, enabling commissioning, monitoring, and basic control without requiring a connected PC or engineering software. The panel features a 5-digit LCD display and a keypad for parameter navigation, making it an essential accessory for field commissioning and maintenance of MICROMASTER 4 drives. It can be mounted directly on the inverter face or remotely in a cabinet door using an optional mounting kit.

The Siemens 3RH1921-2FA31 is a front-mounting auxiliary switch block from the SIRIUS 3RH19 series, designed to expand the control circuit capacity of SIRIUS 3RT1 power contactors and 3RH1 contactor relays in sizes S0 through S12. It features a 3 NO + 1 NC contact configuration with spring-loaded (cage clamp) terminals, providing maintenance-free, vibration-resistant connections for signaling and interlocking circuits.

The Siemens 3RV1021-1DA15 is a SIRIUS 3RV1 series motor protection circuit breaker designed for reliable overload and short-circuit protection of three-phase motors.
