Relay Protection Pressure Plate Price

The price of relay protection pressure plates varies widely depending on specifications, manufacturer, and application, typically requiring a direct quote from suppliers.

Overview

Relay protection pressure plates, often integrated into pressure relief devices for transformers and tap changers, are critical for detecting sudden pressure increases and triggering protective actions. For example, the MESSKO MPREC® pressure relief device operates at response pressures from 4 to 30 psi, with valve plates and signal pins activating main switching contacts within milliseconds, ensuring fast and reliable protection for transformers and electric coils .

Factors Affecting Price

1. Type and Application: Devices for offshore, wind turbines, or high-voltage transformers may cost more due to specialized materials and certifications .
2. Manufacturer and Brand: Well-known brands like MESSKO, Siemens SIPROTEC, and ABB offer high-reliability devices, which can increase cost .
3. Specifications: Pressure range, response time, and additional features such as directed oil flow or multi-end protection influence pricing .
4. Quantity and Procurement: Bulk orders or industrial contracts may reduce unit cost, while single-unit purchases often require higher pricing.

Typical Suppliers

• DigiKey and Mouser Electronics provide protection relays and related components, though pricing is often listed per unit and may require contacting sales for specialized pressure plates .
• Siemens SIPROTEC and ABB offer modular protection relays and pressure devices for medium- and high-voltage systems, with pricing available upon request .
• Reinhausen (MESSKO MPREC®) specializes in pressure relief devices for transformers and tap changers, suitable for industrial and offshore applications .

Recommendation

Since relay protection pressure plates are highly specialized components, the most accurate way to determine price is to contact the manufacturer or authorized distributor with your specific requirements, including pressure range, application type, and quantity. This ensures you receive a quote tailored to your system and compliance needs.
