What this 5SJ6532-7 does in the panel
The Siemens SENTRON 5SJ6532-7 is a 1P+N miniature circuit breaker rated 32 A at 240 V AC, with a C tripping characteristic and 6 kA breaking capacity per EN 60898 (also rated 6 kA per IEC 60947-2). The 1P+N configuration switches the line pole and provides a switched neutral, so the neutral is disconnected when the breaker is off — useful for single-phase final circuits where you want isolation on both conductors. Rated for 440 V insulation voltage and overvoltage category III, it handles the transient environment of a distribution board. The 20 000 mechanical switching cycles give it a solid service life for a panel that sees regular switching, not just fault protection. Pollution degree 2 rating means it's suited for normal industrial or commercial environments with only non-conductive contamination.
Installation and panel fit
Installation depth is 70 mm, and it occupies 2 width units (about 36 mm on a standard rail). The IP20 rating applies with connected conductors; the terminals are touch-protected per the product feature listing. Halogen-free and silicon-free construction means it won't off-gas corrosive compounds in a fire — relevant for panels in critical infrastructure or controlled environments. Sealable with a lead seal for tamper-proofing in metering or rental applications.
Environmental range and compliance
That -40 °C floor matters for unheated electrical rooms or outdoor enclosures in cold climates. The 75 °C ceiling is the internal temperature limit — not the ambient; the breaker itself can withstand that internal temperature without nuisance tripping or damage.
Sourcing and supply posture
For volume procurement or scheduled releases, a blanket order with fixed pricing can be structured.
