The Siemens SENTRON 5SL3113-7 is a 1-pole miniature circuit breaker (MCB) rated 13 A at 30 °C with a C tripping characteristic, meaning it trips at 5 to 10 times rated current — the standard choice for moderate inrush loads like small motors, lighting circuits, and general-purpose outlets in residential and light commercial panels.
Rated current is 13 A at 30 °C ambient, but derates to 12.37 A at 40 °C and 11.36 A at 55 °C — a consideration when the breaker shares a crowded enclosure with other heat sources. Rated operational voltage is 400 V AC single-phase (250 V AC single-phase), with a maximum of 440 V AC for multi-phase operation. The DC rating is 72 V maximum — useful for control circuits but not for high-voltage DC bus protection.
Physical fit and compliance
Dimensions: 18 mm wide (1 modular unit), 90 mm high, 76 mm deep (installation depth 70 mm). Degree of pollution 2, overvoltage category III. Touch protection is built in. Halogen-free and silicon-free construction. Sealable (can be locked in the OFF position). Complies with IEC 81346-2 and DIN EN 61346-2 designation F.
