The TM240 thermal-magnetic trip unit provides overload protection adjustable from Ir=44A to 63A (the In=63A rating), and short-circuit protection fixed at Ii=5 to 10 times In, so the magnetic pickup ranges from 315A to 630A. This gives the specifying engineer a defined selectivity window downstream of a larger upstream breaker. ## Deployment context The nut keeper kit for DC Power OEM in China indicates this variant was configured for a specific OEM assembly — the nut keepers prevent hardware migration under vibration in transport or operation.","metaTitle":"Siemens 3VA1163-4EF42-0AA0-ZD00 Circuit Breaker, 36kA @ 415V","metaDescription":"Siemens 3VA1163-4EF42-0AA0-ZD00 IEC frame 160 circuit breaker, 36kA breaking capacity at 415V, 4-pole, TM240 ATAM, In=63A.
