Under EN 60898 it's rated 4.5 kA — that's the residential / light-commercial benchmark. Under IEC 60947-2 it's 6 kA, the industrial standard for branch-circuit protection. And for UL 1077 / CSA C22.2 No. 235 it's 5 kA, which matters if the panel ships into a North American jurisdiction that recognizes supplementary protectors. Width is 18 mm (one DIN module). The breaker accepts top and bottom combined terminals — wire up clean without needing separate feed-through lugs. It's sealable (lockable in the off position) for lockout/tagout. IP20 with conductors connected — standard for inside the enclosure, not for wet locations. Halogen-free and silicon-free construction, so it won't outgas corrosive compounds in a sealed panel. Pollution degree 3, overvoltage category III — suitable for industrial environments where the breaker sees transient surges from upstream distribution.","metaTitle":"Siemens 5SY3132-7 SENTRON MCB, 1P C-Curve 32A, 4.5kA","metaDescription":"Siemens SENTRON 5SY3132-7 miniature circuit breaker, 1-pole, C-curve, 32 A, 4.5 kA (EN 60898) / 6 kA (IEC 60947-2). 18 mm wide.

The only difference is the tripping curve: 5SY3132-7 is C-curve; 5SY3132-6 is B-curve. If the panel's coordination study calls for B-curve (lower magnetic trip threshold, typically for resistive loads or long cable runs), swapping to a C-curve breaker may change selectivity with downstream devices."},{"question":"Where can I buy the 5SY3132-7 and how is it quoted?","answer":"Sourced and quoted to order against an RFQ through independent industrial-automation distribution.
