Product details

The Siemens 5SU9304-1KK32 is a SENTRON RCBO — an RCD-operated circuit breaker that combines overcurrent protection and residual-current detection in a single 18 mm-wide module. The IP20 rating applies only when the distribution board is installed with connected conductors.

At 40 °C the continuous current drops to 30.08 A; at 45 °C to 29.12 A; at 50 °C to 27.84 A; and at 55 °C to 25.92 A. If the panel runs warm — common in crowded enclosures — the effective capacity is lower than the label. Factor this into the load schedule.

Frequently asked questions

What is the 5SU9304-1KK32 used for?

It is an RCBO (RCD-operated circuit breaker) that provides both overcurrent protection (32 A, Type C) and residual-current protection (30 mA, Type AC) in a single 18 mm-wide DIN-rail module. It is used in distribution boards for commercial and light-industrial installations where combined protection is required.

Where can I buy 5SU9304-1KK32?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at the time of quotation.

What is the difference between 5SU9304-1KK32 and 5SY4116-7CV?

The 5SY4116-7CV is a Siemens SENTRON MCB (miniature circuit breaker) only — it provides overcurrent protection but no residual-current detection. The 5SU9304-1KK32 is an RCBO that adds 30 mA RCD protection in the same 18 mm footprint. If the panel requires both overcurrent and earth-leakage protection in one device, the 5SU9304-1KK32 is the correct choice; the 5SY4116-7CV would need a separate RCD module.
