Product details

The Schneider Electric C080H42AFM is a fixed-mount, 4-pole ComPacT NS new generation MCCB rated 800 A at 50 °C, fitted with a MicroLogic 2.0 A electronic trip unit. This is the distribution-grade breaker for main or feeder protection in a 400 V class switchboard — the 70 kA Icu at 415 V AC (per IEC 60947-2) tells you it can safely interrupt a 70 kA fault without welding or rupturing, which is the figure that governs upstream transformer and busbar coordination.

The MicroLogic 2.0 A provides L (long-time overload) and I (instantaneous short-circuit) protection — no short-time delay or ground-fault element. That makes it a straight replacement for a thermal-magnetic breaker in a distribution board where you want the precision and thermal memory (20-minute reset curve) of an electronic trip. The LCD display shows real-time ammeter readings and fault codes via four red LEDs (fault indication) and one yellow LED (overload).

Fixed backplate mount, 280 mm wide × 327 mm high × 147 mm deep, with a 70 mm connection pitch. IP40 enclosure protection (no gasket against water, so indoor switchgear only) and IK07 impact resistance.

Frequently asked questions

What is C080H42AFM's breaking capacity at 415 V?

70 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2. That is the rating that drives selectivity coordination in a 400 V distribution board.

What trip unit does the C080H42AFM use?

A MicroLogic 2.0 A electronic trip unit with L (long-time overload) and I (instantaneous short-circuit) protection, plus an LCD ammeter display.

Where can I buy the C080H42AFM?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What compliance documentation does this brand provide for C080H42AFM?

The breaker is certified to EN/IEC 60947-2. The manufacturer provides a declaration of conformity and test reports for the breaking capacity ratings listed on this page.
