Overview
RTX-EFP groups six documented protector variants under public RITOKS model codes. Five models are listed with short-circuit protection; RTX-EFP-L80 is separately listed with leakage protection. All six list overvoltage, undervoltage, overload, internal over-temperature protection and RS485 communication.
The brochure does not state current-limiting response time, let-through energy, breaking capacity or a model-specific certification. Those parameters must not be assumed and should be requested before engineering approval.
Key Features
- Single-phase variants with maximum currents of 20A, 63A or 80A
- Three-phase variants with maximum currents of 80A or 250A
- Model-dependent short-circuit or leakage protection
- Overvoltage, undervoltage, overload and internal over-temperature protection listed across the family
- One RS485 communication interface for monitoring integration
Available Models
Protection scope differs by model. RTX-EFP-L80 is the leakage-protection variant; the other five models are listed with short-circuit protection.

Selection Notes
- Confirm single-phase or three-phase circuit architecture.
- Select the maximum current rating required by the circuit.
- Choose leakage protection or the catalog-listed short-circuit protection scope.
- Confirm RS485 protocol and monitoring-platform compatibility.
- Request response-time, limiting-performance, wiring and model-specific compliance documents before final approval.
Frequently Asked Questions
What current range is available?
The documented family includes single-phase 20A, 63A and 80A variants plus three-phase 80A and 250A variants.
Do all models include leakage protection?
No. Leakage protection is listed for RTX-EFP-L80. The other five models are listed with short-circuit protection.
Is RS485 communication included?
The brochure lists one RS485 communication interface for each documented model. Protocol and platform compatibility should be confirmed before ordering.
What current-limiting performance is stated?
The brochure names the product family as current-limiting protectors but does not state response time, let-through energy or breaking capacity. Those values must be requested for the selected model.
