The Siemens 5SJ4210-8HG41 is a 2-pole miniature circuit breaker from the 5SJ4 series, featuring a D tripping characteristic for high inrush current applications. It is rated for 10A at 400V AC supply voltage with an insulation voltage of 440V AC. The breaker offers a switching capacity of 10 kA according to EN 60898 and 15 kA per IEC 60947-2, making it suitable for branch circuit protection in industrial panels.
This MCB is designed for overvoltage category III and degree of pollution 3 environments. It has a mechanical service life of 10,000 switching cycles. The protection class is IP20 with connected conductors and IP40 in the handle range. It operates at 50 Hz rated frequency.
The D-trip characteristic provides delayed tripping to accommodate motor starting currents and other high inrush loads. The 2-pole configuration allows simultaneous disconnection of both phase conductors in single-phase or two-phase circuits.
The rated current is 10A.
It has a D tripping characteristic.
The rated supply voltage is 400V AC, with a maximum operating voltage of 240V AC per UL 489 and 60V DC (single channel) or 125V DC (2-channel).
The switching capacity is 10 kA according to EN 60898 and 15 kA according to IEC 60947-2.
It has 2 poles.
