SENTRON 5SY6302-6CC — Type B 2 A MCB for 3-pole protection
The Siemens 5SY6302-6CC is a SENTRON miniature circuit breaker with a Type B tripping characteristic, rated 2 A at 35 °C, 3-pole construction, and a 6 kA breaking capacity per EN 60898. Rated current is temperature-dependent: at 40 °C it derates to 1.91 A, at 50 °C to 1.81 A, and at 55 °C to 1.75 A. The surrounding temperature influence limits are specified up to 75 °C, with humidity constraints at each level. The 3-pole design (3P) switches all three phases simultaneously; there is no switched neutral (neutral conductor switching is not fitted). This suits it for three-phase loads or as a feeder breaker where neutral is bonded elsewhere.
Combined terminals at both top and bottom accept standard copper conductors. The breaker is sealable — useful for utility or metering applications where tamper evidence is required.
The product designation (miniature circuit breaker) and the energy limitation class 3 indicate it limits let-through energy to protect downstream wiring. The product is suited for mechanical engineering and industry applications per the manufacturer's suitability classification.
