Siemens 7RE2800-0CA00 is a SIPROTEC 7RE28 voltage balance relay for generator protection applications. The exact article is specified for 100/110 V measuring voltage and 50/60 Hz operation. It uses the 7XP2020-2L housing with panel-flush mounting and four rear terminal modules. The front assembly carries an IP51 degree of protection in the documented configuration. Existing voltage-transformer, trip and auxiliary circuits must be checked before replacement.
The 7RE2800-0CA00 monitors the relationship between voltage quantities in an engineered protection scheme. It is commonly maintained as part of an established generator-protection panel rather than installed as an isolated device. Relay settings and terminal wiring should be recorded before removal. Functional secondary-injection and trip-circuit tests are required after installation. Exact article matching supports a controlled replacement while preserving the original panel layout.
Supports balance monitoring in an engineered generator-protection scheme.
Fits the documented flush-mounted 7XP2020-2L relay position.
Provides an exact article for planned relay replacement and testing.
Connected measuring circuits provide the configured voltage quantities.
The relay compares the relevant electrical conditions according to its settings.
A qualifying imbalance is evaluated against the engineered protection logic.
Relay contacts initiate alarm or trip functions through the panel circuit.
The documented article supports both 50 Hz and 60 Hz systems.
100/110 V input data supports protection-panel verification.
The 7XP2020-2L enclosure preserves the installed mounting format.
Four rear terminal modules can be checked against the circuit drawing.
The documented measuring-voltage value is 100/110 V at 50 or 60 Hz.
The specified panel-flush housing is 7XP2020-2L with four rear terminal modules.
Perform the project’s secondary-injection, contact and trip-circuit verification procedures.
The label, front panel, rear terminal modules and enclosure condition are inspected.
The relay is packed and released for courier collection immediately after final inspection.
Send the voltage-transformer, auxiliary supply, output contact and trip-circuit drawings.
The company began in Xiamen, Fujian, China, with a four-person team serving selected European and North American automation customers. Early work centered on building product knowledge, dependable sourcing processes, and practical international trade experience.
By 2017, the team had grown to approximately 30 people and established a warehouse for in-stock automation components. The business expanded across Europe, North America, and Southeast Asia while sourcing capabilities widened to include scarce and discontinued industrial automation parts.
In 2026, a wider professional team supports customers worldwide from inquiry through sourcing, order coordination, delivery, and after-sales communication. The company continues to supply popular, hard-to-find, and discontinued automation components while building long-term international partnerships through responsible service.
