Schneider MT06N1 Air Circuit Breaker – Obsolete MT Series Spare Part

DriveKNMS maintains RFQ-reviewed sourcing status of the MT06N1. This is not a catalog listing. If it appears here, it is because we have assessed and confirmed availability. For plant managers and maintenance engineers operating legacy electrical infrastructure, this is a direct path to avoiding a forced capital expenditure cycle.

RFQ support for obsolete parts: Send the model number, required quantity and destination so DriveKNMS can confirm sourcing options before quotation.

Technical Specifications

Note: Electrical parameters such as rated current, breaking capacity, and pole configuration are model-specific. Contact us with your original panel documentation for cross-verification before ordering.

Solving the Discontinued Hardware Crisis

The core problem with discontinuation is not the part itself — it is the system dependency. A single MT06N1 may protect a 400V feeder circuit that powers a PLC rack, a servo drive cluster, or a critical HVAC loop. When that breaker trips and cannot be reset, or when it fails to trip under fault conditions due to aging mechanisms, the downstream risk is not just equipment damage — it is safety exposure and regulatory liability.

Sourcing an original MT06N1 eliminates the need to re-engineer the protection coordination study, re-certify the panel, or retrain maintenance staff on a new product family. For facilities operating under ISO 9001 or IEC 60364 compliance frameworks, maintaining original component specifications is not a preference — it is a documentation requirement.

Condition & Reliability Assurance

All MT06N1 units sourced through DriveKNMS undergo a structured 5-step assessment protocol before dispatch:

1. Electrolytic Capacitor Aging Check: Internal timing and trip mechanism components are inspected for capacitor degradation, which is the primary failure mode in aged circuit protection devices stored beyond 10 years.
2. Mechanical Trip Mechanism Verification: Each unit is manually cycled through its full trip-and-reset sequence to confirm spring tension, latch engagement, and handle travel are within original specification.
3. Contact Resistance Measurement: Main contact resistance is measured to detect erosion or oxidation that would compromise current-carrying capacity under load.
4. Terminal Pin and Busbar Corrosion Inspection: All connection points are examined under magnification for corrosion, tin whisker formation, or mechanical deformation that would affect installation torque and contact integrity.
5. Firmware / Calibration Traceability (where applicable): For electronic trip units, firmware version and calibration date stamps are recorded and disclosed to the buyer prior to shipment.

Condition grade (New, Refurbished-Grade-A, or Tested-Used) is disclosed in writing with each order. No unit is shipped without a condition report.

Key Features for System Maintenance

• Drop-in replacement: The MT06N1 installs directly into existing DIN rail or panel mount positions without modification to the enclosure or wiring.
• No reprogramming required: Unlike successor product families, the MT06N1 requires no parameter configuration, communication setup, or software commissioning.
• Protection coordination preserved: Using the original part number maintains the existing selectivity study and avoids the cost of a new coordination analysis by a qualified electrical engineer.
• Avoids engineering reconstruction costs: Substituting a non-equivalent breaker in a certified panel can void the panel's type-test certification. The MT06N1 preserves the original certification basis.
• Immediate operational continuity: For facilities where production cannot be halted for panel re-engineering, the MT06N1 is the only path to same-configuration restoration.

Q: Can you source other MT Series variants?
