Table 2-1 Reaction Of The Ps 305;(2 A) Power Supply Module To Atypical Operating Conditions - Siemens SIMATIC S7-300 Manual

Line protection
The mains supply of the PS 305 power supply module (2 A) should be protected with a
miniature circuit-breaker (for example Siemens 5SN1 series) of the following rating:
● Rated current at 110 VDC: 10 A
● Tripping characteristics (type): C.
