It incorporates an ETU320 LI electronic trip unit, providing adjustable long-time and instantaneous settings. The 3-pole breaker mounts into Siemens P5 panelboards, switchboards, and motor control centers. With a Class M breaking capacity of 35kAIC at 480V, this 3VA6 frame MCCB is HACR rated, current limiting, and fully suitable for reverse feed applications.
Which electronic trip unit is included with this Siemens 3VA65 frame breaker?
This breaker features the Siemens ETU320 microprocessor trip unit. This specific module provides adjustable Long-Time (L) and Instantaneous (I) overcurrent protection.
What type of equipment is the 3VA6580-5HL32-0AA0 designed to be installed in?
This 800A molded case circuit breaker is engineered for integration into Siemens P5 panelboards, modular switchboards, and motor control centers (MCC).
How are electrical connections made to the 3VA6580-5HL32-0AA0?
This breaker is equipped with nut keeper hardware rather than standard mechanical wire lugs. The nut keepers allow for direct bolting of busbars or compression ring terminals. If wiring directly with cables, compatible mechanical lugs accepting 2/0 AWG to 600 kcmil copper or aluminum conductors must be added.
Is the 3VA6580-5HL32-0AA0 rated for 100 percent continuous current?
No, this catalog number designates a standard 80 percent rated circuit breaker. Siemens models in this series that are rated for 100 percent continuous load will typically feature a suffix ending in -2AA0.
What does the Class M breaking capacity indicate for this model?
In the Siemens 3VA nomenclature, Class M represents a Medium Low interrupting tier. For this 800A frame, it provides an interrupting capacity of 35kA at 480V and 18kA at 600V, which covers standard commercial fault current requirements.
