Product details

The MGN60543 is a C60N miniature circuit breaker from the Schneider Electric Multi9 range, a D-curve thermal-magnetic unit rated 1 A at 50 °C with 4 protected poles. It snaps onto a 35 mm symmetrical DIN rail, occupies 8 x 9 mm pitches (72 mm wide), and is built to EN/IEC 60947-2, Category A. At 1 A, this is a low-current branch or control-circuit protector, not a main feeder.

Breaking capacity and what it means for your panel

Rated Icu (ultimate breaking capacity) hits 20 kA at 240 V AC phase-to-phase, 10 kA at 415 V, and 6 kA at 440 V — all per EN/IEC 60947-2. The Ics (service breaking capacity) is 75 % of those figures: 15 kA at 240 V, 7.5 kA at 415 V, 4.5 kA at 440 V. The 4-pole version (4P) switches all phases and neutral; the separate earth-leakage block (Vigi add-on) is an option, not built in.

Integration notes for the panel builder

Mounts fixed on 35 mm DIN rail. The toggle gives local ON/OFF indication and a contact position indicator confirms the state.

Frequently asked questions

Where can I buy MGN60543 and get a price?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm number.

What is the closest alternative to MGN60543 in the C60 family?

Within the C60 series, the C60H and C60L are higher-breaking-capacity siblings (typically 25 kA and 36 kA at 240 V) but share the same 4-pole DIN-rail footprint, terminal layout, and D-curve options. The C60N is the standard-duty tier; stepping to H or L gains fault-current headroom without changing the panel cutout or wiring.

What compliance documentation does Schneider provide for MGN60543?

The breaker is certified to EN/IEC 60947-2, Category A, with pollution degree 3. It carries CE marking for the European market. RoHS and REACH declarations are standard for the Multi9 range; specific certificates are available from Schneider's documentation portal or on request with an order.
