At 40 °C it derates to 18.8 A, at 50 °C to 17.4 A, and at 70 °C to 14.6 A. Mounting position is any, so vertical or horizontal DIN-rail orientation won't change the thermal performance.
Touch protection is built in. The supply cord can enter from top or bottom, giving flexibility in panel layout. IP20 rating applies when installed in a distribution board with connected conductors — it's not a standalone outdoor device.
Rated 20 A at 30 °C, 30 mA Type A residual current, B tripping curve, 6 kA breaking capacity per EN 60898, 2-pole, 2 modular width units (36 mm).
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is listed here.
The depth is 77 mm, with an installation depth of 70 mm. Width is 36 mm (2 MW), height is 90 mm.
The 5SU1356-6KK20 is an RCBO (overcurrent + residual current combined), while the 5SY5202-6 is a miniature circuit breaker only (no residual protection). They share the same 2-MW DIN-rail footprint, but the 5SU1356-6KK20 adds the 30 mA Type A residual current trip — wiring and circuit design must account for that difference. Physical fit is the same; functional substitution depends on whether residual current protection is required.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
