The 32 A rated current at 400 V AC sets the continuous load this MCB can carry without tripping under normal conditions. For a 3-phase motor drawing 32 A per phase, this 2-pole breaker protects two of the three phases — typically used in a 2-pole protected scheme where the third pole is a switched neutral or the load is single-phase. The D-curve trips magnetically between 10 and 20 times rated current (320–640 A), which is deliberately above the startup spike of most induction motors; a C-curve (5–10× In) would trip on the same motor's inrush. The 72 V DC maximum rating allows use in DC control circuits up to that voltage, but note the DC breaking capacity is not the same 10 kA — verify the DC performance curve if used on a DC bus. ## Installation and mounting Height is 90 mm. Combined terminals at both top and bottom allow looping through without separate distribution blocks. Sealable — the toggle can be locked in the ON or OFF position with a padlock, meeting lockout/tagout requirements. Touch protection is integral; IP20 with connected conductors means finger-safe but not protected against water ingress.","metaTitle":"Siemens 5SY4232-8CC11 SENTRON MCB, 2P D 32 A, 10 kA","metaDescription":"Siemens 5SY4232-8CC11 SENTRON miniature circuit breaker, 2-pole, D-curve, 32 A, 10 kA breaking capacity per EN 60898, 400 V AC.

This is the maximum fault current the breaker can safely interrupt at rated voltage. For DC circuits up to 72 V, the DC breaking capacity is not specified as 10 kA — consult the DC performance data if used on a DC bus."},{"question":"What wire sizes does 5SY4232-8CC11 accept?","answer":"Solid conductors from 0.75 to 35 mm²; stranded conductors from 0.75 to 35 mm². The 35 mm² upper limit is generous for a 32 A breaker — it allows use with larger conductors for voltage drop mitigation on long runs."},{"question":"Where can I buy 5SY4232-8CC11?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
