Siemens 3VA5580-6EC32-0AA0 Molded Case Circuit Breaker

No. This breaker is equipped with a nut keeper kit, which is intended for busbar or compression lug attachments. If you need to terminate standard copper or aluminum cables, you must order the appropriate mechanical lug kits separately based on your specific wire gauge and conductor count.

The TM230 thermal-magnetic trip unit features a fixed thermal overload (Ir) set permanently to 800 amps. However, the instantaneous magnetic short-circuit protection (Ii) is adjustable from 4,000 to 8,000 amps, allowing you to dial in the trip point between 5 and 10 times the continuous current rating.

This 3VA55 frame breaker is designed for direct integration into Siemens 3VA panelboards and modern switchboards. It can also be installed into Siemens P4 and P5 panelboards, provided you use the correct strap kit and mounting hardware assembly.

Yes, the 3VA5 series is the modern upgrade path for legacy Siemens CMD and CND frame breakers, including common models like the CMD63B800 and CND63B800. When retrofitting this newer SENTRON frame into an existing panel, be aware that updated mounting brackets or deadfront modifications will likely be required.

The LI trip function code stands for Long-Time and Instantaneous protection. The Long-Time thermal element protects the system against sustained, low-level overloads, while the Instantaneous magnetic element trips the breaker immediately during severe short-circuit faults.

No, this specific model is a standard 3-pole line protection breaker without a neutral protection feature. Systems that require monitored or switched neutrals will need a 4-pole breaker or a more advanced electronic trip unit configuration.
