No adjustment dials means no risk of an incorrect setting during commissioning — the protection curve is locked at the factory. The nut keeper kit included with this variant is specific to DC Power OEM builds in China, so verify the mounting hardware matches your enclosure's gland plate before panel integration.","metaTitle":"Siemens 3VA1140-4ED32-0AA0-ZD00 Circuit Breaker, 40A, 36kA @","metaDescription":"Siemens 3VA1140-4ED32-0AA0-ZD00 IEC frame 160 circuit breaker, 3-pole, 40A fixed thermal-magnetic, 36kA breaking capacity @ 415V.
