SIEMENS 3RV1923-2GA00 Motor Protection Circuit Breaker (MPCB) Accessory / Shunt Trip Coil

‌1. Product Name‌
SIEMENS 3RV1923-2GA00 Motor Protection Circuit Breaker (MPCB) Accessory / Shunt Trip Coil

‌2. Product Brief Introduction‌
The SIEMENS 3RV1923-2GA00 is an accessory module for the Siemens SIRIUS 3RV series of Motor Protection Circuit Breakers (MPCBs). Specifically, it is likely a shunt trip coil or undervoltage release, designed to provide remote tripping or automatic disconnection functionality to the base MPCB, enhancing its control and safety features.

‌3. Product Description‌
The SIEMENS 3RV1923-2GA00 is a specialized accessory designed to expand the functionality of a Siemens SIRIUS 3RV series Motor Protection Circuit Breaker (MPCB). While the primary 3RV MPCB provides integrated short-circuit and overload protection for a ‌SIEMENS MOTOR‌, this accessory module, typically a shunt trip or undervoltage release, adds a layer of remote or automatic control. A shunt trip coil allows the MPCB to be opened (tripped) remotely by an external electrical signal. This is crucial for safety systems where a ‌SIEMENS MOTOR‌ must be shut down immediately from a central location, such as when an emergency stop button is pressed, a fire alarm is activated, or a safety interlock (like a guard door switch) is broken. An undervoltage release automatically disconnects the circuit if the supply voltage falls below a safe threshold, protecting the ‌SIEMENS MOTOR‌ from damage that could occur if it attempts to restart under unstable voltage conditions. This module is designed for straightforward, clip-on attachment to a compatible 3RV base MPCB, requiring no additional panel space. By integrating this accessory, the protection scheme for a ‌SIEMENS MOTOR‌ becomes more intelligent and responsive. It enables integration with wider plant safety and automation systems, allowing for coordinated emergency shutdowns or preventing motor operation under unsafe electrical conditions. This enhances both personnel safety and equipment protection, ensuring that the ‌SIEMENS MOTOR‌ and the system it drives can be controlled and protected not just locally, but also through automated or remote safety commands.

‌5. Product Advantages ‌

• ‌Enables Remote Tripping / Safety Shutdown:‌ As a shunt trip, it allows the MPCB protecting a ‌SIEMENS MOTOR‌ to be tripped remotely via an electrical signal, enabling integration with emergency stop circuits, fire alarms, or other safety systems for immediate power cutoff.

• ‌Provides Undervoltage Protection:‌ If configured as an undervoltage release, it automatically disconnects the ‌SIEMENS MOTOR‌ circuit when the supply voltage drops below a safe level, preventing potential damage from brownouts or unsafe restart attempts.

• ‌Enhances System Safety and Automation:‌ Integrates the motor protection device into broader safety and control loops, allowing for automated responses to external alarms or conditions, significantly improving overall system safety.

• ‌Modular and Easy Installation:‌ Designed as a snap-on or clip-on accessory for specific 3RV MPCBs, it is easy to install without tools and does not require additional panel space, maintaining a compact design.

• ‌Reliable Siemens Compatibility:‌ Engineered and tested by Siemens to ensure perfect mechanical and electrical compatibility with the corresponding SIRIUS 3RV circuit breakers, guaranteeing reliable operation.

‌6. Website Analysis & Insights‌
Based on the provided  for the website ‌www.wheat-auto.com‌, which belongs to ‌Changzhou Wheat Automation Technology Co., Ltd.‌, the analysis reveals the following key insights into its business:

• ‌Core Business Model:‌ The company operates as an ‌international supplier, distributor, and trader‌ of a wide variety of industrial automation components and electronic products. It is explicitly ‌not a manufacturer‌ but a ‌trading and sourcing intermediary‌ or channel.

• ‌Product Portfolio & Role:‌ The website functions as a ‌one-stop sourcing platform‌, listing a vast array of branded components from numerous global manufacturers. Prominently featured brands include ‌SIEMENS MOTOR‌, ABB MOTORS, DeWalt, Endress&Hauser, Krohne, Honeywell, METTLER TOLEDO, Yokogawa, and many others across diverse categories like sensors, instruments, and tools.

• ‌Target Market:‌ The website's multilingual interface (English, Chinese, Russian) clearly indicates a strategic focus on the ‌global B2B market‌, targeting international clients in industrial automation, manufacturing, and related sectors.

• ‌Value Proposition & Operations:‌ Their stated principle is ‌"quality first, reputation first."‌ Their core service is ‌global supply chain management and logistics‌, providing customers worldwide with access to specific branded components. Their operational model appears to be a ‌direct-sales, inquiry-based model‌. The "News" section functions as a product catalog/promotion feed, listing specific part models (e.g., Siemens 6GK6000-8FX, 3VA2225-5H) and providing direct contact methods like WhatsApp (+86 15951219765) and email (info@wheat-auto.com). This suggests they cater to buyers who are actively searching for exact part numbers and contact them directly for transactions.

• ‌Company Profile:‌ They describe themselves as a high-tech electronics company established in 2012, emphasizing building long-term business relationships and creating higher market value through quality and service.

‌Interpretation:‌ Changzhou Wheat Automation Technology Co., Ltd. positions itself as a ‌global commercial bridge and sourcing partner‌. Their expertise lies in international trade, sourcing, and the distribution of specialized industrial parts. They connect global manufacturers (like Siemens) with international end-users, system integrators, and distributors, leveraging their supply network to fulfill specific component requests for products like the SIEMENS 3RV1923-2GA00.

‌7. Use Scenarios‌

• ‌Emergency Stop (E-Stop) Circuits:‌ Integrated into safety systems where pressing an E-stop button sends a signal to the shunt trip coil, instantly disconnecting power to a ‌SIEMENS MOTOR‌ driving a potentially hazardous machine (e.g., press, mixer, conveyor).

• ‌Safety Interlock Systems:‌ Used in conjunction with guard doors or light curtains on machinery. If the guard is opened or the light curtain is breached, a signal trips the MPCB via the shunt trip, stopping the ‌SIEMENS MOTOR‌ to protect personnel.

• ‌Fire and Hazard Alarm Integration:‌ Connected to building or process fire/gas alarm systems. Upon alarm activation, a signal is sent to trip the MPCB, shutting down ‌SIEMENS MOTORs‌ for fans, pumps, or conveyors in the affected area.

• ‌Automatic Shutdown on Power Loss (UV Release):‌ Configured as an undervoltage release to automatically disconnect a ‌SIEMENS MOTOR‌ circuit when power fails, preventing automatic and potentially unsafe restart when power returns (anti-plugging).
