All 1-pole and 2-pole 5SJ, 5SY and 5SP4 miniature circuit breakers
can be used in DC systems up to 60 V or 120 V.
For higher voltages, 5SY5 and 5SP5 versions are required.
In contrast to to other product ranges, the arcing chamber area
of the 5SY5 and 5SP5 are equipped with an additional perma-
nent magnet to support the positive quenching of the electric
arc.
For this reason, the polarity of the switch is coded and must be
observed when connecting the conductor.
Up to max. 220 V DC battery voltage
Up to max. 220 V DC battery voltage
Up to max. 440 V DC battery voltage.
