ABB TMAX T1N160 – Compact MCCB for dependable circuit protection up to 160 A
The ABB SACE Tmax T1N160 is a compact molded case circuit breaker designed for reliable protection of feeders, small distribution panels, and OEM equipment up to 160 A. One thing I appreciate is how the T1 frame keeps footprints small without giving up on short-circuit performance. It’s a very practical drop-in for machinery builders, commercial switchboards, or quick upgrades where space and mounting time really matter.

Key Features
- T1 frame up to 160 A: Suited for small feeders, motor groups, and panel sub-circuits where compactness is key.
- “N” breaking capacity level: The T1N variant typically covers mainstream short-circuit duties in commercial and light industrial boards.
- Thermal-magnetic trip (common build): Predictable overload and short-circuit protection; adjustable thresholds available depending on the exact trip unit code.
- Accessory-ready: Add auxiliary contacts (OF/SD), shunt trip, or undervoltage release for interlocking and remote signaling.
- Flexible mounting: Fixed front mounting on backplate; DIN-rail adapters are available when panel standards require it.
- Standards compliance: Built for IEC 60947-2 applications; variants commonly carry UL 489 listings for North American panels.
- Tight, sturdy terminals: From my experience, terminal design on T1s handles vibration reasonably well when torqued correctly.
Technical Specifications

| Product Type | Molded Case Circuit Breaker (MCCB), IEC 60947-2 |
| HS Code | 8536.20 (Automatic circuit breakers) |
| Rated Current Frame | Up to 160 A (final In depends on the selected trip unit) |
| Breaking Capacity (“N” level) | Typical Icu at 400/415 V AC falls in the mainstream range for the T1N; exact kA rating varies by detailed catalog code. |
| Poles | 3P or 4P variants available |
| Power Requirements | None for breaker operation; accessories (shunt trip/UVR) require rated control voltage |
| Operating Temperature | Typically -25 °C to +55 °C (application derating may apply at higher ambients) |
| Signal I/O | Optional OF (auxiliary), SD (trip) contacts; shunt trip; undervoltage release |
| Communication Interfaces | Not native; status via auxiliary contacts (fieldbus requires external modules, if used) |
| Installation Method | Fixed front mounting on panel/backplate; busbar/line-load screw terminals; DIN-rail adapters available |

- Terminal covers & interlocks: Enhanced IP protection and mechanical interlocking between breakers.
Installation & Maintenance
- Mounting environment: Install inside a ventilated cabinet meeting IEC/UL panel standards. Keep ambient within specified range; derate above ~40 °C as per ABB curves.
- Wiring: Use correctly sized cables/busbars; tighten to ABB torque values. From my experience, a second torque check after thermal cycling helps prevent hot spots.
- Accessories: Fit OF/SD contacts, shunt trip, or UVR per wiring diagrams. Verify control voltages before energizing coils.
- Safety: Isolate the supply and lockout/tagout before any work. Verify absence of voltage; use terminal shields where required.
- Routine care: Annual dust cleaning, mechanical operation test, and visual checks for discoloration or loosened conductors. Trip unit settings should be verified after any load changes.
You might notice that T1 units run cool when correctly torqued and sized; unexpected warmth usually points to connection issues or oversizing of the load.
Quality & Certifications
- Manufactured to IEC 60947-2; CE marked; many variants UL 489 listed
- RoHS compliant; produced under ISO 9001 quality systems
- Warranty: 365 days (coverage from our side)
Customer note (typical feedback): “Swapped a legacy T1N160 into an older machine panel—holes lined up, and the rotary handle kit saved us a door cutout. Short downtime, zero callbacks.”
