Product details

What this 3VA1 MCCB carries

This Siemens 3VA1120-5EF32-0AA0-ZD00 is a 3-pole IEC molded-case circuit breaker on the 3VA1 frame (160 A frame size). It is rated for line protection with a TM240 thermal-magnetic trip unit, set for a 20 A nominal current (In) with overload protection adjustable from 14 A to 20 A (Ir). Short-circuit protection (Ii) is fixed at 8 to 16 times In.

The nut keeper kit keeps the terminal hardware captive during wiring — a small detail that saves time on repetitive builds. Rated for IEC 60947-2 compliance, it is suited for main or branch-circuit protection in industrial switchgear where the 55 kA interrupting rating at 415 V provides headroom for high-fault installations.

Frequently asked questions

What is the breaking capacity of this MCCB?

The Icu (ultimate breaking capacity) is 55 kA at 415 V AC, class M. That is the maximum short-circuit current it can safely clear without failure, and it sets the SCCR for the downstream panel.

Where can I buy 3VA1120-5EF32-0AA0-ZD00?
