Product details

Breaking capacity and protection profile

The 3VA1163-6MH32-0HH0: This 3VA1 IEC frame 160 MCCB carries a 70 kA breaking capacity at 415 V (class H), meaning it can safely interrupt a fault current up to that level without upstream fuses needing to clear first — a critical spec for panel SCCR coordination in a 415 V distribution board. The 63 A thermal-magnetic trip (TM120M) provides short-circuit protection adjustable from 5 to 15 x In, but note the description explicitly states it ships without overload protection, so this unit is intended for applications where overload protection is handled upstream or by a separate motor starter relay.

Integrated control and signalling

Factory-fitted with a shunt trip (STL) rated 12–30 V DC and 24 V AC 50/60 Hz, plus two HQ auxiliary switches and one HQ trip alarm switch.

Frequently asked questions

What is the breaking capacity of this MCCB?

70 kA at 415 V (IEC breaking capacity class H). This is the maximum fault current the breaker can safely interrupt at that voltage level.

Does this breaker include overload protection?

No. The description states it is configured for short-circuit protection only (Ii = 5–15 x In) without overload protection. Overload coordination must be provided upstream or by a separate motor starter.

What auxiliary contacts are fitted?

Two HQ auxiliary switches and one HQ trip alarm switch are factory-installed. The shunt trip (STL) operates on 12–30 V DC or 24 V AC.
