Snaps onto DIN rail via the quick-assembly system — 36 mm wide (2 width units), 90 mm tall, 76 mm deep, with a 70 mm installation depth behind the panel. IP20 with connected conductors, touch-protected terminals, and sealable — that last one matters for installations where the inspector wants a tamper-evident cover over the adjustment dial. The 5SY3 design is the standard SENTRON MCB platform, widely stocked and cross-referenced. Halogen-free and silicon-free construction, so it's suitable for clean-room or food-processing panels where outgassing matters. Ambient temperature range -25 to +55 °C operating, -40 to +75 °C storage; humidity derating applies above 55 °C (max 95% RH at 55 °C, dropping to 35% at 75 °C). Overvoltage category III, energy limiting class 3 — that's the standard for branch-circuit protection in fixed installations. DC rating: 72 V max, 15 kA per IEC 60947-2 — covers 48 V and 60 V DC control circuits common in telecom and solar combiner boxes. The 2-pole configuration with both poles switched gives full isolation on a single-phase AC feed or a two-wire DC circuit. Position of the supply cord is any, so line and load can enter from either end without reconfiguring the busbar.","metaTitle":"Siemens 5SY3206-6 SENTRON MCB, 2P, 6A, B Curve, 4.5kA","metaDescription":"Siemens 5SY3206-6 SENTRON miniature circuit breaker, 2-pole, 6 A, B characteristic, 4.5 kA per EN 60898.
