Product details

The Siemens SENTRON 5SL6206-7BB is a 2-pole miniature circuit breaker (MCB) with a C-trip curve, rated 6 A at 400 V AC, and a 6 kA breaking capacity certified to both EN 60898 and IEC 60947-2.

At 36 mm wide (2 modular units) and 76 mm deep, this MCB drops onto any standard DIN rail. Mounting position is unrestricted — vertical, horizontal, or upside-down in a tight gland plate — no derating needed for orientation.

Thermal derating — the real-world number

The 6 A rating holds at 30 °C; at 40 °C it's 5.68 A, at 55 °C it's 5.17 A. The mechanical life is 10 000 switching cycles typical, which is fine for a distribution breaker not cycled daily.

Frequently asked questions

Where can I buy 5SL6206-7BB and how is it quoted?

We source it to order through independent distribution. Submit an RFQ for current pricing and availability — no minimum quantity assumed, and we confirm lead time at quote.

What are the key ratings of the 5SL6206-7BB?

2-pole, C-curve, 6 A rated current at 400 V AC, breaking capacity 6 kA per both EN 60898 and IEC 60947-2. Width is 36 mm (2 MW), depth 76 mm, mounting position any.

Will 5SL6206-7BB drop into a panel specified around 5SL3340-7CC?

Both are 2-pole C-curve MCBs on a 36 mm footprint, so the mechanical fit is the same. The 5SL6206-7BB is rated 6 A / 6 kA; the 5SL3340-7CC is a different current/kA variant — verify the load and fault level before swapping. No rewiring needed if the busbar and terminals match.

What compliance documentation does Siemens provide for 5SL6206-7BB?

The MCB is halogen-free and silicon-free. It carries IP20 protection with connected conductors and is rated for overvoltage category III, pollution degree 2. Standard Siemens declarations (CE, UKCA) accompany the shipment; RoHS/REACH status is available on request.
