Schneider Electric MT32N1 Air Circuit Breaker – Masterpact MT Series
When an unprotected power distribution system experiences a fault current, the consequences are immediate and catastrophic: arc flash events, equipment destruction, unplanned downtime, and in the worst cases, loss of life. In mission-critical industrial environments — from steel mills and data centers to offshore platforms and large commercial buildings — the absence of a reliable air circuit breaker means there is no last line of defense between a fault and a full facility shutdown. The Schneider Electric MT32N1 is precisely that defense: a high-performance air circuit breaker engineered to interrupt fault currents with speed, precision, and repeatability that conventional molded-case breakers simply cannot match.
The MT32N1 belongs to Schneider Electric’s Masterpact MT series, the flagship range of low-voltage air circuit breakers designed for main and tie breaker applications in demanding power distribution architectures. Within the Masterpact MT lineup, the MT32N1 occupies the 3200 A frame class with a standard breaking capacity (N-rated), making it the preferred choice for engineers who require robust overcurrent protection without over-specifying to the higher H or L breaking capacity tiers. Globally, the Masterpact MT series is recognized as a benchmark product in IEC 60947-2 compliant switchgear, deployed across more than 100 countries and trusted by EPC contractors, panel builders, and end-users in the most demanding industrial and infrastructure sectors.

Frequently Asked Questions
- Q: What is the difference between MT32N1, MT32H1, and MT32L1?
- A: The suffix N, H, and L denote the breaking capacity class. N is standard breaking capacity, H is high, and L is very high (limiting). The MT32N1 is the N-rated 3200 A, 3-pole variant — suitable for most standard industrial distribution applications where the prospective short-circuit current does not exceed the N-rated Icu value.
- Q: Is the MT32N1 available in both fixed and drawout versions?
- A: Yes. The Masterpact MT series supports both fixed and drawout mounting configurations. Please specify your requirement when submitting your RFQ so we can confirm the correct part number and chassis assembly.
- Q: Which Micrologic trip unit should I select for the MT32N1?
- A: Trip unit selection depends on your protection coordination requirements. Micrologic 2.0 A provides basic LSI protection; Micrologic 5.0 E adds earth fault protection; Micrologic 6.0 E adds measurement; Micrologic 7.0 adds power quality metering. Our engineers can assist with protection coordination studies.
- Q: Can Konmask.com provide the original Schneider Electric test certificate?
- A: Yes. All units we supply come with the original manufacturer’s factory test certificate and full traceability documentation as standard.
- Q: What is the typical lead time for the MT32N1?
- A: Lead time varies by stock availability. Ex-stock units can ship within 3–5 business days. For non-stock items, typical lead time is 4–8 weeks depending on Schneider Electric’s production schedule. Contact us for a real-time availability check.
