Product details

The Siemens 5SY7506-8 is a SENTRON miniature circuit breaker (MCB) with a D tripping characteristic, rated 6 A at 35 °C on AC supply at 50/60 Hz.

Breaking capacity — the dual rating matters

The EN 60898 rating of 15 kA is the lower bound for installations that fall under that standard's scope.

Thermal derating — don't size by the 35 °C number alone

The 6 A rating holds at 35 °C ambient. Above that, the bimetal strip heats earlier: 5.63 A at 40 °C, 5.44 A at 45 °C, 5.24 A at 50 °C, 5.04 A at 55 °C, and 4.82 A at 60 °C. If the panel ambient runs at 50 °C, this breaker will carry 5.24 A continuously before the thermal trip element starts to bend — not 6 A.

Installation depth is 70 mm (total depth 76 mm). Sealable with a lead seal for tamper-evident applications.

Frequently asked questions

Where can I buy 5SY7506-8 and how do I get a price?

The 5SY7506-8 is available to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time, no stock-count or lead-time figures published here.

Will 5SY7506-8 drop into a panel specified around 5SY7210-7CC without rewiring?

The 5SY7506-8 and 5SY7210-7CC share the same SENTRON family footprint (2 MW, 36 mm wide, same DIN-rail clip) and the same 1P+N pole configuration, so mechanical fit is identical. The difference is the trip curve and rating: the 5SY7506-8 is a 6 A D-curve; the 5SY7210-7CC is a different rating and characteristic. Verify the branch-circuit protection requirements before swapping — the physical swap is straightforward, but the protection coordination may change.

What compliance documentation does Siemens provide for 5SY7506-8?

Siemens provides RoHS and REACH declarations, manufacturer declarations of conformity to EN 60898 and IEC 60947-2, and the product is halogen-free and silicon-free. Documentation is included with the shipment or available on request.
