This breaker carries an H1 performance class: 66 kA Ics at 220/415 V, 440 V, 500/525 V, and 660/690 V AC. That's the service breaking capacity — the current it can clear and still be used again without inspection. The Icw short-time withstand is also 66 kA for 0.5, 1, and 3 seconds, which gives you real headroom for selective coordination downstream. Making capacity (Icm) hits 145 kA peak at 415 V, meaning it can close into a bolted fault and survive. ## Physical fit and mounting constraints Fixed-mount design, 537 mm wide, 352 mm tall, 300 mm deep. Connection pitch is 115 mm. Mounts on rails or a base plate. Neutral sits on the right. IP30 enclosure rating — it's for switchgear cubicles, not washdown areas. ## Environmental and application limits Rated insulation voltage is 1000 V AC, operational voltage 690 V AC. Impulse withstand is 12 kV — covers the typical surge environment in industrial power systems. ## Durability and power loss Mechanical endurance is 20,000 cycles with periodic preventive maintenance. Electrical durability varies by duty: 6,000 cycles under AC-3 (motor switching) at 440/690 V, 5,000 cycles under AC-23A at 440 V. Maximum break time is 25 ms, closing response 70 ms. Power dissipation runs 420 W at rated current — factor that into your cubicle ventilation. ## Standards compliance and documentation Meets EN/IEC 60947-1, EN/IEC 60947-2, EN/IEC 60947-2 Annex H (for selectivity), and IEC 61557-12 (for power metering if equipped). Control is push-button type; this variant ships without a control unit — you add the Micrologic trip unit separately.","metaTitle":"Schneider Electric LV848187 MasterPact MTZ2 32 H1, 3200 A, 4","metaDescription":"LV848187 MasterPact MTZ2 32 H1 circuit breaker, 3200 A at 40 °C, 4 poles, 66 kA Ics at 415 V AC.

The physical footprint and connection pitch are the same across MTZ2 fixed-mount units, so swapping performance class doesn't change your panel layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LV848187","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/LV848187 when reusing this data.
