The NEC Class 2 rating (per UL 1310) means the output is limited-energy, which simplifies wiring in industrial control panels — no separate overcurrent protection required on the load side for most applications. The UL/cULus listing (UL 508, CSA C22.2 No. 107.1) confirms it meets North American industrial control equipment standards. With IP20 protection, it's suited for dry indoor environments inside a cabinet; the housing doesn't seal against moisture ingress, so keep it behind a gland plate or enclosure door. The 2.5 A rated current is the continuous output at 25 °C ambient. Above 55 °C, derate at 2 % per Kelvin up to 70 °C. The DC input range of 110 to 300 V covers nominal 110 V, 125 V, and 220 V DC systems commonly found in railway, telecom, and industrial battery-backed buses. The wide tolerance handles dips and surges without dropping out. Internal fuse protection means no external fuse holder is needed on the output, though the feeder should have a miniature circuit breaker — 10 A characteristic B or 6 A characteristic C recommended upstream. MTBF at 40 °C is 3,723,563 hours. CE marking, EAC approval, and DNV GL marine type approval are on file. Galvanic isolation provides safety extra-low output voltage (SELV) per EN 60950-1 and EN 50178, so it's suitable for feeding control circuits that require separation from mains.","metaTitle":"Siemens 6EP1332-1SH43 Power Supply, 2.5 A, NEC Class 2","metaDescription":"Siemens 6EP1332-1SH43 power supply, 2.5 A rated output, DC input 110-300 V, UL/cULus listed NEC Class 2, IP20, DIN rail mount.
