Product details

The Siemens 5SY4404-6CC is a SENTRON miniature circuit breaker — 4 A rated current, B-curve tripping characteristic, 4-pole (4P) construction, and a 10 kA breaking capacity per EN 60898.

Mounting position is any, which helps when the busbar layout dictates a rotated breaker. Terminal design is combined top and bottom, touch-protected per the product feature, and accepts the usual comb busbar for the feed side.

Ratings and approvals

Rated operational voltage is 400 V AC; multi-phase operation goes to 440 V AC. DC side maxes at 72 V — not a DC-rated breaker for solar or battery strings, but fine for control-circuit isolation. Breaking capacity under UL 1077 and CSA C22.2 No. 235 is 5 kA, which covers most North American supplementary protection applications.

Frequently asked questions

What is the breaking capacity of 5SY4404-6CC?

10 kA per EN 60898 at 400 V AC, and 5 kA per UL 1077 / CSA C22.2 No. 235.

What compliance documentation does Siemens provide for 5SY4404-6CC?

The part carries UL and CSA supplementary protection listings (5 kA), is rated per IEC/EN 60898, and is halogen-free and silicon-free. Standard Siemens declarations of conformity (CE, UKCA) and material compliance (RoHS, REACH) are available with the shipment documentation.

Where can I buy 5SY4404-6CC and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for volume or single-piece needs.

Will 5SY4404-6CC drop into a panel specified around 5SY4301-7CV?

Both are 4-pole SENTRON MCBs on the same DIN-rail footprint (4 MW units). The 5SY4404-6CC is a 4 A B-curve; the 5SY4301-7CV is a different rating. If the panel busbar and wiring are sized for the 5SY4301-7CV's current, the 5SY4404-6CC will physically fit the same slot without rewiring — but verify the ampacity matches the circuit protection requirement.
