The Siemens 3VA1096-2ED42-0AA0-ZD00 is a 4-pole IEC frame 100 circuit breaker with a 16 A rating and a breaking capacity of 16 kA at 415 V (class B). This specific suffix (-ZD00) designates a variant built for DC Power OEMs in China.
The fixed Ir and Ii settings simplify ordering: no adjustment dials, no mis-set trips on site.
The TM210 trip curve is a thermal-magnetic type — thermal element handles overloads, magnetic element handles short-circuits. At 20 × In (320 A magnetic pickup), it's suited for circuits with moderate inrush, like small motor feeders or general distribution.
