Eaton MPB2-TP – Test-Port Accessory for MPB2 Assemblies, Built for Safe, Fast Panel Diagnostics

The Eaton MPB2-TP is a practical test-port accessory that mates with MPB2-series assemblies to give technicians safe, front-access measurement points during commissioning and maintenance. From my experience, it’s the kind of small hardware that saves real time on the plant floor—no need to disturb terminations just to verify voltages or check CT/PT circuits. You might notice that crews rely on it most during start-ups, audits, and any “find it fast” troubleshooting in MCCs or control panels.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Front-access test points – Typically provides touch-safe access to measurement nodes, so you can probe without unwiring field conductors.
• Time-saving for commissioning – Ideal for secondary checks on protection and metering circuits; in many cases, it shortens outage windows.
• No external power – Passive accessory; it doesn’t introduce an extra power dependency into the panel.
• Panel-friendly – Designed to integrate with MPB2 assemblies; secure mounting minimizes accidental pull-out during routine checks.
• Service safety – Touch-proof design elements help reduce arc/short risks when used with appropriate insulated probes.
• Clear identification – Typically shipped with labeling zones so technicians can mark circuits and avoid mis-probing during busy shifts.

Technical Specifications

Field feedback: “We used the MPB2-TP to validate our CT secondaries and voltage presence before energization—cut our test time by half and no wire juggling,” a maintenance supervisor at a food processing plant told us. That seems to be the typical story during tight shutdown windows.

Related or Supporting Products

• Eaton MPB2 – Companion assembly the MPB2-TP is designed to interface with (confirm your MPB2 revision for mechanical fit).
• Eaton insulated test leads – 4 mm probe leads for panel-safe measurements, CAT-rated for industrial environments.
• Eaton labeling kits – Circuit ID/marker kits to keep test points clearly identified in dense cabinets.
• Alternative: panel test jacks – If you’re standardizing on individual test jacks, we can match color-coding and spacing to your existing panels.

Installation & Maintenance

• Cabinet environment – Use in enclosures meeting IEC/UL panel standards; keep airflow unobstructed around measurement wiring to avoid heat clustering.
• Wiring practices – Route test-point conductors away from high-noise sources where possible; maintain bend radii and use ferrules or ring/fork lugs per your spec.
• Safety – De-energize where practical; if live testing is required, use insulated probes and PPE per NFPA 70E/IEC 61482. Verify absence of voltage before touching conductors.
• Routine checks – Inspect quarterly for loosened hardware, worn labeling, or contamination. Clean with a dry lint-free cloth; avoid solvents on plastic surfaces.
• Calibration – Not applicable to the MPB2-TP itself; verify your meters and test equipment are in calibration before use.
• Documentation – From my experience, a quick photo of the test-point labeling in the panel logbook prevents probing errors later.

Quality & Certifications

• Manufacturing quality typically aligned with ISO 9001 processes
• CE and RoHS compliance expected for panel accessories
• UL recognition/listing may apply when installed within a compatible Eaton assembly (check your MPB2 assembly file)
• Manufacturer’s warranty: 12 months from shipment (365 days)

If your installation uses a specific MPB2 revision or unique panel cutout, share a photo or the assembly code and we’ll confirm mechanical compatibility and any minor kit variations before you place the order.
