Product details

The Siemens SENTRON 5SM1311-6 is a 2-pole residual current circuit breaker (RCCB) rated 16 A at 40 °C, with a 30 mA trip threshold and Type A sensitivity. It sits on a DIN rail (REG) in a distribution board, occupying 2 modular width units. Type A detection covers sinusoidal AC and pulsating DC residual currents, which covers most modern electronics and single-phase rectified loads.

Temperature derating and real-world current

Above that, it derates linearly: 15.36 A at 50 °C, 14.72 A at 55 °C, 14.08 A at 60 °C, and 12.8 A at 70 °C.

Rated according to EN 60898 (0.5 kA) and IEC 61008-1 (0.5 kA). Overvoltage category III. The I²t let-through is 70,000 A²·s; surge current resistance is 1 kA. The test circuit supply voltage minimum is 100 V AC.

Frequently asked questions

What is the closest functional second-source for 5SM1311-6?

The 5SU9354-7KK16 is a similar 2-pole RCCB from the same SENTRON family, but verify the trip characteristic and width before substituting — the 5SM1311-6 is an instantaneous Type A device at 30 mA. Panel rewiring is not required if the footprint matches, but the SCCR and temperature derating curves differ.

What is the maximum ambient temperature for 5SM1311-6?

Maximum operating ambient is 45 °C; storage maximum is 60 °C. Current derating begins above 45 °C.

What compliance documentation does Siemens provide for 5SM1311-6?

The device is rated to EN 60898 and IEC 61008-1, and carries an IP20 rating when installed. Silicon-free construction is declared. Full RoHS/REACH/UL documentation is available from Siemens upon request through the supply channel.

Where can I buy 5SM1311-6 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no online stock figure is published for this channel.
