Product details

Mounts via the quick-assembly system (DIN rail) in any position — no derating needed for horizontal or inverted orientation. The 3-pole body occupies 3 width units (54 mm) on the rail, with a depth of 76 mm and an installation depth of 70 mm behind the panel surface. IP20 with connected conductors is standard for enclosed distribution boards; the sealable option lets the panel builder lock the toggle position to prevent unauthorized switching during commissioning or maintenance.

Energy limiting class 3 means this MCB limits the let-through energy (I²t) to a low level, which improves downstream device protection and aids selective coordination with upstream breakers. The 10 kA SCCR at 400 V AC covers most industrial panel fault levels; for higher available fault currents, verify the upstream device's let-through curve against the MCB's withstand. Combined top and bottom terminals allow loop-through wiring without extra busbars — a time-saver on the panel wireman's bench.

Frequently asked questions

What is the breaking capacity of the 5SY4301-7CC11?

10 kA per EN 60898 at 400 V AC. This is the standard breaking capacity for the SENTRON 5SY4 series and suits most industrial distribution boards.

Where can I buy the 5SY4301-7CC11?

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 commitment.

What compliance documentation does Siemens provide for this MCB?

The 5SY4301-7CC11 carries EN 60898 certification for breaking capacity and is designed for railway applications, which implies compliance with EN 50155. The halogen-free and silicon-free declaration supports RoHS and REACH alignment. Specific certificates (UL, CSA, IEC) should be confirmed from the manufacturer's documentation package.
