Product details

Integrator note — 5SL7204-7RC

The Siemens 5SL7204-7RC is a Betagard miniature circuit breaker, 2-pole, C-curve, rated 4 A at 415 V AC. Temperature derating is published: at 40 °C the continuous rating drops to 3.76 A, at 50 °C to 3.48 A, at 60 °C to 3.24 A.

Panel fit and compliance

Width 18 mm per pole (36 mm for the 2-pole unit). Sealable, halogen-free, silicon-free; IP20 with conductors connected. Rated supply voltage is 415 V AC, maximum 440 V AC for both single-phase and multi-phase operation. Frequency 50/60 Hz. No DC rating is listed — this is an AC-only device for distribution boards feeding resistive, lighting, or moderate motor loads.

For a BOM freeze or multi-year project, the Betagard line is a standard Siemens MCB family with broad panel acceptance. If a second-source cross-reference is needed, the SENTRON 5SY7210-7CC is a 2-pole 10 A C-curve breaker with 25 kA IEC breaking capacity and a 36 mm width — same depth and installation depth, but higher current and wider footprint. The 5SL7204-7RC is the 4 A, 18 mm-per-pole option for lower-current branches.

Frequently asked questions

Where can I buy 5SL7204-7RC and how is it quoted?

The 5SL7204-7RC is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is 5SL7204-7RC's listed depth?

Depth is 76 mm; installation depth is 70 mm.

What is 5SL7204-7RC's listed width?

Width is 18 mm per pole, so the 2-pole unit occupies 36 mm total (2 modular width units at 18 mm each).

Will 5SL7204-7RC drop into a panel specified around 5SY7210-7CC without rewiring?

No — the 5SL7204-7RC is 18 mm wide per pole versus the 5SY7210-7CC's 36 mm total width, so the DIN-rail footprint is the same (2 modular units), but the 5SL7204-7RC is rated 4 A versus 10 A; the branch circuit must be sized for 4 A. Depth and installation depth match at 76 mm and 70 mm respectively.

What compliance documentation does Siemens provide for 5SL7204-7RC?

The breaker carries ratings per EN 60898 (15 kA) and IEC 60947-2 (20 kA), is halogen-free and silicon-free, and is rated for overvoltage category III and pollution degree 2. Standard Siemens documentation includes these declarations; specific RoHS/REACH/UL certificates should be requested at quote time.
