Hirschmann BRS20-04009999-TTCX99HHSESXX.X.XX Four-Port EEC-HL Network Selection with Temperature and Installation Approval Checks
Hirschmann BRS20-04009999-TTCX99HHSESXX.X.XX is the BRS20-4TX-EEC-HL configuration of the Hirschmann BOBCAT family. This configuration is relevant when a four-port copper switch must be selected against both an environmental requirement and an installation approval requirement. The EEC-HL suffix and complete product code distinguish it from visually similar BRS20 switches.
Use Type BRS20-4TX-EEC-HL together with numeric part 942170034 when comparing the supplier offer with the engineering request.
Keep the EEC-HL ordering identity intact
The catalog lists ISA12.12.01 under hazardous locations for this code. Engineering should check the current certificate, supplied device marking and installation conditions before approving a location; a suffix alone is not a complete area classification.
Can a standard four-port BRS20 replace the EEC-HL version?
Only after the project requirements are rechecked. Matching RJ45 ports does not establish matching temperature ratings, approval conditions or order-code options.

Review the required industrial profile
- Network integration and location approval are separate checks.
- EtherNet/IP, PROFINET, Modbus TCP and IEC 61850 MMS switch-model entries appear in the catalog; ask which profile and software revision the project requires. None of these protocol references establishes hazardous-location suitability by itself.
Electrical installation record
Catalog supply: 2 x 12 VDC ... 24 VDC; listed power consumption: 5 W. An EEC-HL purchase needs an installation review alongside the electrical schedule. Verify terminal wiring and protection using the instructions for the delivered device, and retain the accepted supply arrangement with the project documents used to approve the equipment location.
Prepare an HKXY quotation request
Enquiry reference: Hirschmann BRS20-04009999-TTCX99HHSESXX.X.XX; Type BRS20-4TX-EEC-HL; part 942170034.
Attach the location requirements and required installation documents to the enquiry, alongside quantity and destination. HKXY can use the exact EEC-HL identity to prepare the quotation; any proposed alternative should be clearly identified for engineering review.
Technical reference: Belden catalog configuration for BRS20-4TX-EEC-HL. Confirm the current datasheet and supplied hardware revision before final engineering approval.
