The TM240 thermal-magnetic trip unit provides overload protection adjustable from Ir=350A to 500A, with short-circuit pickup Ii set at 5 to 10 times In (2.5 kA to 5 kA). This is a line-protection breaker, not a motor-circuit protector; the TM curve suits feeder and distribution applications where the load is resistive or mixed, not high-inrush motor starts. ## Deployment context — panel integration and OEM fit The nut keeper kit included with the -ZD00 suffix is specific to DC Power OEM builds in China — it retains the busbar nuts during assembly, saving time on high-density panels where access is tight. The 3-pole form factor fits standard 3VA1 accessories: shunt trips, auxiliary switches, and undervoltage releases share the same mounting slots across the frame 630 family.","metaTitle":"Siemens 3VA1450-4EF32-0AA0-ZD00 Circuit Breaker, 500A, 36kA","metaDescription":"Siemens 3VA1450-4EF32-0AA0-ZD00 IEC frame 630 circuit breaker, 3-pole, 500A, 36kA breaking capacity @ 415V.
