Price of Relay Protector Short Circuit

Relay protectors for short-circuit protection typically range from $50 to over $1,000 depending on type, brand, and application.Overview

Relay protectors are devices designed to detect overcurrent or short-circuit conditions and disconnect power to prevent damage to electrical systems, equipment, and users . They are widely used in industrial, commercial, and residential applications, including motor control, power distribution, and automation systems . Popular brands include Littelfuse, Siemens SIPROTEC, and other industrial suppliers .

Price Range
  • Basic AC sensor or small relay modules for low-current applications (up to 100A) can cost $50–$150 .
  • Industrial-grade protection relays for medium-voltage or high-current systems, such as Siemens SIPROTEC or Littelfuse arc-flash relays, typically range from $500 to $1,500 or more depending on features like microprocessor control, ground-fault monitoring, and multi-pole tripping .
  • Custom or specialized relays for critical infrastructure or high-voltage applications may exceed $2,000, especially when including software, adapters, and mounting hardware .
Factors Affecting Price
  1. Current and voltage rating – Higher ratings require more robust components.
  2. Functionality – Relays with arc-flash protection, ground-fault detection, or programmable logic are more expensive.
  3. Brand and certification – Reputable brands with compliance to industrial standards (FAA, IEC, UL) cost more.
  4. Accessories – Modules with current transformers, mounting kits, or software add to the total cost.
Where to Buy
  • DigiKey offers a wide selection of circuit protection devices, including relays, with online pricing and same-day shipping .
  • Littelfuse provides industrial and commercial protection relays with detailed specifications and catalog access .
  • Siemens SIPROTEC relays are available through authorized distributors and provide modular, high-voltage protection solutions . For exact pricing, it is recommended to check supplier websites or request a quote, as prices vary based on configuration, quantity, and shipping.
