How to Send an RFQ for Siemens Products

Sending a Request for Quotation (RFQ) is one of the most important steps in the procurement process for industrial automation, electrical distribution and infrastructure projects. A well-prepared RFQ helps suppliers identify products accurately, provide quotations faster and reduce the risk of delays during project execution.

Understanding how to send an RFQ for Siemens products can significantly improve procurement efficiency, especially for EPC contractors, industrial operators, consultants, utilities, panel builders and system integrators.

Whether the requirement involves Siemens low-voltage products, medium-voltage equipment, protection relays, switchgear, PLC systems, HMI panels or industrial drives, providing the right information from the beginning helps suppliers deliver accurate and competitive quotations.

Why RFQs Matter in Industrial Procurement

Industrial projects often involve hundreds or even thousands of components.

A properly prepared RFQ helps:

• Reduce Quotation Time
• Improve Pricing Accuracy
• Avoid Product Identification Errors
• Improve Procurement Efficiency
• Reduce Project Delays
• Simplify Technical Review

Incomplete RFQs frequently result in:

• Additional Clarification Requests
• Incorrect Product Selection
• Longer Lead Times
• Procurement Delays
• Budget Uncertainty

For large industrial projects, the quality of the RFQ often determines the efficiency of the entire procurement process.

How to Send an RFQ for Siemens Products Correctly

The first step in learning how to send an RFQ for Siemens products is understanding what information suppliers require.

The most effective RFQs typically include:

• Siemens Part Numbers
• Product Descriptions
• Quantities
• Technical Specifications
• Project Information
• Delivery Location
• Required Delivery Date

Providing complete information helps suppliers identify products quickly and accurately.

Siemens Part Numbers: The Most Important Information

The fastest way to receive a quotation is to provide Siemens part numbers.

Example:

• Budgetary Pricing Exercises

In these situations, provide:

• Product Type
• Electrical Ratings
• Technical Requirements
• Application Details

For example:

Need a Siemens MCCB
400A
50kA breaking capacity
3-pole
Industrial application

This information allows suppliers to recommend suitable products.

What Is a BOM?

A Bill of Materials (BOM) is one of the most effective ways to send an RFQ for Siemens products.

A typical BOM contains:

• Part Number
• Description
• Quantity
• Unit of Measure

Example:

BOMs help suppliers process large quotations efficiently.

What Is a BOQ?

A Bill of Quantities (BOQ) is commonly used in EPC and infrastructure projects.

BOQs may include:

• Equipment Lists
• Cable Quantities
• Distribution Equipment
• Switchgear Requirements
• Protection Devices
• Automation Systems

Providing a BOQ helps suppliers understand overall project requirements.

How to Send an RFQ for Siemens Products Using Single Line Diagrams

Single Line Diagrams (SLDs) are extremely valuable during quotation preparation.

They help suppliers understand:

• System Architecture
• Voltage Levels
• Distribution Networks
• Protection Requirements
• Equipment Relationships

SLDs are particularly useful for:

• Switchgear Projects
• Substations
• Industrial Facilities
• Power Distribution Systems

Technical Specifications That Improve RFQs

Technical specifications help suppliers verify suitability.

Useful information includes:

Voltage

Examples:

• 230V
• 400V
• 690V

• 33kV

Current Rating

Examples:

• 100A
• 400A
• 1600A

Breaking Capacity

Examples:

• 25kA
• 50kA
• 100kA

Communication Requirements

Examples:

• PROFINET
• Modbus
• IEC 61850

These details improve quotation accuracy.

How to Send an RFQ for Siemens Products for Low Voltage Systems

Low-voltage RFQs commonly involve:

• Circuit Breakers
• Contactors
• Motor Starters
• Distribution Boards
• Protection Devices

Important information includes:

• Current Rating
• Breaking Capacity
• Pole Configuration
• Application Type

Providing these details accelerates product selection.

How to Send an RFQ for Siemens Products for Medium Voltage Projects

Medium-voltage projects typically require more technical information.

Applications include:

• Substations
• Utility Networks
• Industrial Facilities
• Power Plants

Useful information includes:

• Voltage Level
• Fault Level
• Protection Requirements
• Switchgear Configuration

Medium-voltage RFQs often require engineering review before quotation.

How to Send an RFQ for Siemens Products for Protection Relays

Protection relay quotations are easier when the following information is provided:

• Application Type
• Voltage Level
• Protection Functions
• Communication Requirements
• Existing System Information

Examples include:

• Feeder Protection
• Transformer Protection
• Motor Protection
• Generator Protection

How to Send an RFQ for Siemens Products for PLC Systems

PLC RFQs should include:

• Communication Requirements
• Expansion Requirements

Examples:

• SIMATIC S7-1200
• SIMATIC S7-1500
• ET200 I/O Systems

Automation projects often require technical consultation before final selection.

How to Send an RFQ for Siemens Products for HMI Systems

Useful information includes:

• Screen Size
• Application Type
• Communication Protocol
• Environmental Requirements
