Product details

The Siemens 6EP1332-4BA00 is a SITOP PSU8200 power supply delivering a rated output of 3 A over a 0 to 3 A range. It accepts a wide AC input: 85 to 132 V or 170 to 264 V, with automatic range selection, at line frequencies of 45 to 65 Hz. The unit provides a safety extra-low output voltage (SELV) per EN 60950-1, EN 50178, and EN 61132-2, making it suitable for control circuits in industrial panels. For hazardous area deployment, this unit carries ATEX (EX) II 3G Ex nA nC IIC T4 Gc and IECEx Ex nA nC IIC T4 Gc certifications, along with FM approval for Class I, Div. 2, Group ABCD, T4. It is also cULus-Listed (UL 508, CSA C22.2 No. 142) and holds DNV GL marine approval, EAC, and CE marking.

The power supply mounts directly onto an S7-1500 rail via its fastening method. The datasheet specifies a top clearance of 40 mm and a bottom clearance of 40 mm, with 0 mm required on the left and right sides. This compact footprint allows tight side-by-side placement on the DIN rail, but the vertical clearance must be maintained for natural convection cooling during operation from 0 to 60 °C.

Wiring and Feeder Protection

The manufacturer recommends a 10 A characteristic B or 6 A characteristic C miniature circuit breaker in the feeder. The maximum I²t value is 1.3 A²·s, and the typical no-load current draw is 0.4 mA, rising to a maximum of 3.5 mA.

Frequently asked questions

What certifications does the 6EP1332-4BA00 carry?

The unit carries ATEX (EX) II 3G Ex nA nC IIC T4 Gc, IECEx Ex nA nC IIC T4 Gc, cULus-Listed (UL 508, CSA C22.2 No. 142), FM Class I Div. 2, DNV GL marine, EAC, and CE marking.

What are the clearance requirements for mounting?

The datasheet specifies 40 mm clearance above and below the unit, with 0 mm required on the left and right sides, allowing tight side-by-side mounting on the S7-1500 rail.

What is the rated output current?

The rated output current is 3 A over a 0 to 3 A range, with a safety extra-low output voltage per EN 60950-1 and EN 50178.

How does the 6EP1332-4BA00 compare to the 6EP1336-3BA00?

The 6EP1336-3BA00 is a higher-output sibling in the same SITOP PSU8200 family, offering a higher current rating. The 6EP1332-4BA00 is the 3 A variant, while the 6EP1336-3BA00 serves applications requiring more current. Both share the same form factor, mounting rail, and hazardous-area certifications, so a panel designed for one can typically accept the other without rewiring, provided the feeder protection and wiring are sized for the higher current.
