Product details

Breaking capacity and duty class

The Siemens 5SY4380-7 is a 3-pole, C-curve miniature circuit breaker from the SENTRON series, rated 10 kA breaking capacity at 400 V AC per EN 60898 and 15 kA at DC per IEC 60947-2. The C-curve trips at 5–10× rated current, making it suited for mixed resistive and inductive loads in control panels. The DC rating of 15 kA at 60 V (max 72 V) covers DC auxiliary circuits common in switchgear and automation cabinets.

Mounting and environmental range

Compliance and production status

Certified to IEC/EN 60898-1 and IEC/EN 60947-2; also to UL/CSA standards with 5 kA breaking capacity for North American installations. Halogen-free and silicon-free construction supports clean-room and sensitive-environment installations.
