The Siemens 3VA1180-3GF42-0AA0-ZD00 is a 4-pole circuit breaker from the 3VA1 IEC frame 160 series, rated at 80 A with a breaking capacity class N and an Icu of 25 kA at 415 V. It carries TM240 overload protection with an adjustable Ir range of 56 to 80 A and short-circuit protection set at 5 to 10 times In. This is a line-protection breaker, not a motor-protection device — the TM240 thermal-magnetic trip is sized for feeder and distribution panels, not for starting-duty overload curves.
This breaker includes 100% N-conductor protection and a nut keeper kit, and is specified for a DC Power OEM application in China. The nut keeper kit simplifies panel assembly — keeps hardware captive during mounting in a distribution board or enclosure. The 4-pole configuration with full neutral protection suits TN-S or TN-C-S systems where the neutral needs to be switched and protected alongside the phases.
