The 5SJ4204-7HG42: Rated 400 V AC and 60 V DC, this 2-pole breaker handles single-phase or two-wire DC circuits up to that voltage ceiling. The DC rating is limited to 60 V maximum, so it is not a candidate for higher-voltage DC bus applications.
The 5SJ4 series is an active Siemens SENTRON line. No official successor or cross-reference on record.
Yes, rated 60 V DC maximum. It is suitable for two-wire DC circuits up to that voltage, but not for higher-voltage DC bus applications.
