Eocr Fdm
Overview
Product sourcing insights & recommendations


The phrase "EOCR FDM" refers to a specialized series of Electronic Over-Current Relays (EOCR) primarily manufactured by Schneider Electric (formerly Samwha EOCR). These devices are digital, microprocessor-based motor protection relays designed to monitor and protect three-phase motors from various electrical faults ThietbidienschneiderManuals.
Product Overview & Key Features
The EOCR-FDM series is distinguished by its flush-mounting design, allowing the display module to be installed on a panel door for external monitoring while the relay unit remains inside ImajteknikAlibaba.
* Core Protection: Provides comprehensive monitoring for overcurrent, undercurrent, phase loss, phase unbalance, phase reversal, and locked rotor/stall conditions WiautomationWiautomation.
* Digital Diagnostics: Features a sequence-displaying digital ammeter (L1-L2-L3 every 5 seconds) and stores the cause and current values for the last three trip events ThietbidienschneiderStudylib.
* High Scalability: While direct current ranges typically cover 0.5A to 60A, the use of external Current Transformers (CTs) allows protection for motors up to 960A ThietbidienschneiderWiautomation.
* Energy Efficiency: Offers significantly lower power consumption compared to traditional thermal bimetallic relays, contributing to overall system reliability and reduced heat generation ThietbidienschneiderAlibaba.
Market Trends & Insights (2025-2026)
The protective relay market, which includes EOCR devices, is experiencing a shift toward digital, networked, and intelligent systems FortunebusinessinsightsLinkedin.
* Market Growth: The global protective relay market is projected to grow from $2.80 billion in 2025 to nearly $4 billion by 2032, with a CAGR of 5.22% Fortunebusinessinsights.
* Smart Grid & IoT Integration: Demand is driven by smart grid modernization and the integration of renewable energy sources, which require Intelligent Electronic Devices (IEDs) for bidirectional power flow monitoring Fortunebusinessinsights.
* Digitalization: There is a strong transition from legacy electromechanical relays to numerical relays like the EOCR-FDM due to their superior accuracy, self-diagnostic capabilities, and communication protocols (e.g., Modbus) StudylibManuals.
* Regional Dominance: The Asia-Pacific region (particularly China and India) remains the largest market due to massive infrastructure projects and industrial automation initiatives Fortunebusinessinsights.
Sourcing & Pricing Insights
Current market prices for EOCR-FDM units range from $160 to $200+ per piece for original Schneider/Samwha units, depending on the specific supply voltage (e.g., 24V vs. 220V) and order volume AlibabaAlibaba. Verified B2B suppliers are primarily located in China (Xiamen, Shenzhen) and Hong Kong, offering global shipping and technical support AlibabaAlibaba.
