Siemens 3VA5560-6EC32-0AA0 Molded Case Circuit Breaker

Nut keeper terminals indicate the breaker is supplied with hardware designed for attaching compression lugs or busbar connections, rather than standard mechanical box lugs.

The TM230 trip unit provides fixed thermal protection for overloads and adjustable magnetic protection for short circuits. This allows you to fine-tune the instantaneous trip response for your specific application.

Yes, it can be used to retrofit older installations, but it requires 3VA-specific mounting hardware or strap kits designed for your exact panelboard or switchboard type.

Yes, this 3VA55 frame breaker is the modern replacement for legacy Siemens 600A frames, such as the HLMD63B600, when used with the appropriate retrofit mounting kits.

No, this specific catalog number is supplied without internal accessories like auxiliary switches or shunt trips. However, the 3VA series features a modular design allowing these accessories to be purchased and field-installed separately.

The adjustable magnetic trip allows electricians to set the instantaneous short-circuit pickup level. This ensures coordinated fault protection and minimizes arc flash hazards without affecting the continuous 600A overload rating.

Yes, the Siemens 3VA series utilizes a uniform accessory platform, meaning many internal components like auxiliary contacts and alarm switches are interchangeable across 3VA5 and 3VA6 molded case circuit breakers.

The Class H designation indicates a medium interrupting capacity for the 3VA series, which corresponds to its 65kA at 480V rating. This makes it suitable for commercial and industrial environments with moderate fault current levels.
