Product details

The Siemens 5SL4363-7RC is a SENTRON miniature circuit breaker (MCB) rated 63 A with a C tripping characteristic, 3 poles, and a 10 kA breaking capacity per EN 60898 at 415 V AC. The 10 kA breaking capacity at 415 V AC means it can safely interrupt a fault current up to that level without upstream damage, per EN 60898.

Physical fit and integration

At 18 mm wide (1 MW) and 76 mm deep, it snaps onto a standard DIN rail in any mounting position. Sealable terminals are provided for tamper-proofing after commissioning.

Electrical ratings and approvals

Rated for 50/60 Hz operation, overvoltage category III, pollution degree 2. Halogen-free and silicon-free construction.

Frequently asked questions

What is the breaking capacity of the 5SL4363-7RC?

10 kA per EN 60898 at 415 V AC, 3-pole operation.

Where can I buy the 5SL4363-7RC?

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

What is the difference between 5SL4363-7RC and 5SL4363-7?

The 5SL4363-7RC is a single-module-width (18 mm) 3-pole MCB, while the 5SL4363-7 occupies 3 modular width units (54 mm) for the same pole count. Both share the same 63 A C-curve rating, 10 kA breaking capacity, and SENTRON series. The 5SL4363-7RC is the space-saving variant for dense panels.
