Product details

Siemens SENTRON 5SY4306-7CC11 — 3-pole MCB, C-curve, 10 kA

The Siemens 5SY4306-7CC11 is a 3-pole miniature circuit breaker from the SENTRON series, designed with tripping characteristic C and a breaking capacity of 10 kA at 400 V AC per EN 60898.

Railway-rated construction and environmental tolerance

This MCB carries a design-for-railway-applications designation, meaning it meets the vibration resistance of IEC 60068-2-6: ±1 mm at 5 to 25 Hz and 50 m/s² at 25 to 150 Hz. It operates across -40 °C to 75 °C, with humidity tolerance up to 95% at 55 °C, derating to 35% at 75 °C.

Panel integration and compliance notes

Installation depth is 70 mm, with a total depth of 76 mm including the front. The neutral conductor is not switched (3-pole only).

Frequently asked questions

What is the breaking capacity of 5SY4306-7CC11?

10 kA at 400 V AC per EN 60898. It also carries a 440 V AC rating for single-phase and multi-phase operation.

What does tripping characteristic C mean for this MCB?

The C-curve trips between 5 and 10 times rated current, making it suitable for moderate inrush loads like motor starters and small transformers in industrial panels.

Where can I buy 5SY4306-7CC11 and how is it quoted?

This part is sourced and quoted to order through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm quote.

What compliance documentation is available for 5SY4306-7CC11?

The MCB is halogen-free and silicon-free. It meets IEC 60068-2-6 vibration resistance, pollution degree 3, and overvoltage category III. Standard Siemens SENTRON documentation (CE, UKCA, EAC) applies; specific RoHS/REACH declarations are available on request.
