The 2-pole design (2P) switches both line conductors simultaneously, making it suitable for single-phase AC circuits or DC circuits where both poles need coordinated interruption. The C-curve characteristic handles the inrush of inductive loads like contactors and small motors without nuisance tripping, while still providing short-circuit protection. The 10 kA breaking capacity at 400 V AC (per EN 60898) and 15 kA at DC (per IEC 60947-2) means it can safely interrupt fault currents up to those levels — adequate for most commercial and light industrial distribution boards. The 76 mm depth and 36 mm width (2 modular width units) fit standard DIN-rail enclosures; the quick-assembly fastening method and any-position mounting simplify panel integration. ## Standards & Compliance — Dual Certification for Global Shipments The 5SY5232-7 carries dual certification to IEC / EN 60898-2 and UL1077. EN 60898-2 covers DC miniature circuit breakers for household and similar installations; UL1077 covers supplementary protectors for use in industrial control panels. This dual rating simplifies compliance for equipment destined for both European and North American markets — one part number covers both IEC and UL requirements. ## Environmental Range & Mounting Rated for ambient temperatures from -40 °C to 75 °C, with humidity derating above 55 °C: max 95% RH at 55 °C, tapering to 35% at 75 °C. The overvoltage category is III (distribution level), pollution degree 3 (industrial environments with conductive pollution).","metaTitle":"Siemens 5SY5232-7 SENTRON MCB, 2-Pole C-Curve, 400V AC / 440","metaDescription":"Siemens 5SY5232-7 SENTRON miniature circuit breaker, 2-pole, C-curve, rated 400 V AC / 440 V DC, 10 kA breaking capacity.
