Product details

What this power supply delivers

The Siemens 6EP3332-7SB00-0AX0 is a SITOP power supply delivering a rated output of 2.5 A from a DC input spanning 110 to 275 V. Typical current draw sits at 3.1 A. The output is safety extra-low voltage per EN 60950-1, with galvanic isolation between input and output. Feeders should be protected by a circuit breaker from 4 A characteristic C up to 16 A characteristic C, or by the specified 3RV2 series breakers.

Snaps onto DIN rail EN 60715 35x7.5/15 — standard panel integration. Clearance requirements: 50 mm top and bottom, 0 mm left and right. IP20 protection means it's for dry, enclosed control cabinets, not washdown environments. Push-in terminals accept 0.5 to 2.5 mm² single-core or finely stranded wire on both input (/+, L2/N/-, PE) and output (+1, -1, -2) sides.
