The Siemens 3VA1116-6EE32-0AA0-ZD00 is a 3-pole IEC frame 160 circuit breaker rated for line protection with a TM220 thermal-magnetic trip unit. Breaking capacity class H delivers Icu=70kA at 415V — sufficient for high-fault industrial distribution panels where upstream coordination demands a robust interrupting rating. The overload protection is adjustable from Ir=112A to 160A, and the short-circuit pickup is fixed at Ii=10 x In.
Integration and Mounting
Mounts on a DIN rail or can be screw-fixed to a backplate in the panel. The 3-pole footprint fits standard 3VA1 cutouts. Spring-cage terminals accept copper conductors; torque settings per the terminal marking on the device. The nut keeper kit is pre-installed for the DC Power OEM application — verify polarity and voltage rating before energizing.
