Product details

The Siemens 3VA1163-6EF42-0AA0-ZD00 is a 4-pole IEC frame 160 molded case circuit breaker with a 63 A thermal-magnetic trip unit (TM240, ATAM). Its headline rating is the 70 kA breaking capacity at 415 V (class H), which means it can safely interrupt fault currents up to that level on a 415 V three-phase system without upstream coordination failure — a key spec for panel builders targeting high-fault industrial mains.

The breaker includes a nut keeper kit for DC Power OEM in China — a mounting accessory that simplifies panel integration for OEM builds.

Frequently asked questions

What is the breaking capacity of this circuit breaker?

The breaking capacity is Icu = 70 kA at 415 V, class H.

What are the overload and short-circuit protection settings?

Overload protection Ir is adjustable from 44 A to 63 A. Short-circuit protection Ii is fixed at 5 to 10 times In (315 A to 630 A).

How do I get current pricing and availability for 3VA1163-6EF42-0AA0-ZD00?
