Product details

The 3VA1450-6EE42-0AA0-ZD00 is a Siemens 3VA1 IEC frame 630 molded-case circuit breaker with a 70kA breaking capacity at 415V (class H). The thermal-magnetic trip unit is a TM220 ATFM, with adjustable overload protection (Ir) from 350A to 500A and fixed short-circuit pickup at 10 x In (5000A). The 4-pole configuration leaves the neutral conductor unprotected, which is standard for line-side main breakers where the neutral is bonded to ground and does not require overcurrent protection. The nut keeper kit and DC Power OEM designation indicate this variant is packaged for integration into DC power equipment manufactured in China.

For a BOM line requiring a 500A frame 630 breaker with 70kA @ 415V interrupting capacity, this is the exact Siemens order code.

Frequently asked questions

What is the breaking capacity of this breaker?

The 3VA1450-6EE42-0AA0-ZD00 has a rated ultimate breaking capacity (Icu) of 70kA at 415V AC, which places it in breaking capacity class H for the 3VA1 frame.

What are the overload and short-circuit protection settings?

Overload protection (Ir) is adjustable from 350A to 500A via the TM220 ATFM trip unit. Short-circuit protection (Ii) is fixed at 10 times In, or 5000A for this 500A rated breaker.
