Product details

The Siemens 3VA1450-5EE42-0AA0 is a 4-pole IEC frame 630 circuit breaker in the 3VA1 series, rated at In=500A with a breaking capacity Icu=55kA at 415V. Overload protection is adjustable via the TM220 thermal-magnetic trip unit from Ir=350A to 500A, and short-circuit protection is fixed at Ii=10 x In (5000A).

Deployment Context

The 4-pole configuration with unprotected neutral suits it for main or feeder protection in 3-phase, 4-wire distribution boards, switchgear, or MCC buckets. The nut keeper kit simplifies panel assembly by retaining mounting hardware during installation.

Frequently asked questions

What is the breaking capacity of 3VA1450-5EE42-0AA0?

The breaking capacity is Icu=55kA at 415V, which is the 'M' (medium) breaking capacity class per IEC 60947-2. This rating means the breaker can safely interrupt fault currents up to 55kA without damage, suitable for industrial distribution systems with moderate fault levels.

Where can I buy 3VA1450-5EE42-0AA0?
