Siemens 3VA6610-6HN32-0AA0 Molded Case Circuit Breaker

This 1000A breaker is specifically designed for integration into Siemens P5 panelboards, Siemens switchboards, and motor control centers. It is not intended for use in standard load centers or smaller lighting panels.

The nut keeper design provides a retained threaded nut at the terminals, allowing you to bolt busbars or crimp-on compression lugs directly to the breaker. If your installation requires terminating bare wire, you will need to purchase and install compatible mechanical box lugs separately.

The adjustable LSI (Long-Time, Short-Time, Instantaneous) electronic trip unit allows panel builders to fine-tune the breaker's response curve. By adjusting the short-time pickup and delay, you can achieve precise selective coordination with downstream breakers, ensuring that a fault clears at the lowest possible level without tripping the main 1000A breaker.

No, the 3VA6610-6HN32-0AA0 is a panel mount breaker. Due to its size and 1000A capacity, it must be bolted directly to the chassis or buswork of a compatible Siemens switchboard, P5 panelboard, or motor control center.

This unit is part of the Siemens SENTRON family and utilizes the 3VA66 frame. Knowing the frame type is essential when sourcing compatible internal accessories, such as auxiliary switches, shunt trips, or external operating handles designed for the 3VA66 footprint.

Yes. With high interrupting capacities like 65kAIC at 480V and 150kAIC at 240V, this breaker can serve as a fully rated main and protect lower-rated downstream branch breakers. You must consult Siemens series rating tables to verify that your specific combination of main and branch breakers is UL listed for the available fault current.
