The Siemens 3VA1116-3ED42-0AA0-ZD00 is a 3VA1 IEC frame 160 molded-case circuit breaker with a 160 A fixed thermal-magnetic trip unit (TM210). Breaking capacity class N delivers an Icu of 25 kA at 415 V AC, 4-pole configuration, with the neutral pole unprotected. The short-circuit release is fixed at 10 x In (1600 A). This variant includes a nut keeper kit and is specified for DC Power OEM builds in China.
Key Ratings & Fit
The 160 A fixed Ir means the overload protection is non-adjustable — the breaker trips on thermal overload at exactly 160 A continuous. The Ii of 10 x In (1600 A) sets the magnetic instantaneous pickup; this is a fixed value, not field-adjustable. The 25 kA Icu at 415 V is the maximum short-circuit current the breaker can safely interrupt — sufficient for most industrial distribution panels with a transformer rating that keeps prospective fault current under that threshold. The 4-pole design with unprotected neutral is typical for IT or corner-grounded delta systems where the neutral does not require overcurrent protection.
Deployment Context
Mounts in a standard panel enclosure on a DIN rail or direct-mount busbar system. The nut keeper kit simplifies busbar connection during panel assembly — the captive nut stays aligned while torquing the bolt, reducing installation time on repetitive builds.
