Product details

Siemens 5SN4306-7CN — SENTRON 3-pole MCB, C-curve, 6A

It breaks fault currents up to 10 kA at 400 V AC per EN 60898, which covers the majority of commercial and light industrial panelboard applications where the prospective short-circuit current stays under that threshold.

Fit and panel integration

The 5SN4306-7CN occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. It mounts in any position and accepts solid conductors up to 25 mm². Vibration resistance to 50 m/s² at 25–150 Hz per IEC 60068-2-6 means it holds up on machine-mounted subpanels near rotating equipment.

Halogen-free and silicon-free construction. Sealable for lockout/tagout compliance. Touch protection is provided. The operating temperature range is -40 °C to +75 °C, with derating above +55 °C at 95% humidity.

Frequently asked questions

Where can I buy the 5SN4306-7CN and get a price?

The 5SN4306-7CN is 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 commercial offer.

Will the 5SN4306-7CN drop into a panel specified around the 5SL4363-7?

Yes — both share the same 76 mm depth, 54 mm width (3 MW), 90 mm height, DIN-rail mounting, and IP20 rating. The 5SL4363-7 is a higher-current variant (63 A vs 6 A) with a higher per-pole power loss (5 W vs 0.7 W), but the mechanical footprint and connection scheme are identical. No rewiring or panel modification is needed for the swap.

What compliance documentation does Siemens provide for the 5SN4306-7CN?

The 5SN4306-7CN is designed to EN 60898 (10 kA breaking capacity) and IEC 60947-2 (10 kA). It is halogen-free and silicon-free. Standard Siemens SENTRON documentation includes the declaration of conformity, CE marking, and the product datasheet. Specific RoHS/REACH declarations are available from the manufacturer upon request.
