Product FAQs
9 answersWhat panelboards are compatible with the 3VA6115-6HN31-0AA0 circuit breaker?
This 150A breaker mounts in Siemens P2, P3, P4, and P5 panelboards. Appropriate strap kits or mounting hardware are required to secure the breaker to the panelboard bus.
Can the 3VA6115-6HN31-0AA0 be used to replace legacy Siemens 150A breakers?
Yes, the 3VA6 series serves as a modern replacement for discontinued Siemens VL (such as the HDG3B150) and older Sentron (such as the HFD63B150) molded case circuit breakers. A 3VA-specific mounting kit is typically required when retrofitting into older enclosures.
What specific electronic trip unit is installed on this breaker?
The 3VA6115-6HN31-0AA0 is equipped with the ETU350 trip unit. This provides LSI (Long-Time, Short-Time, and Instantaneous) protection with rotary adjustment dials for precise coordination of the tripping curves.
What breaking capacity class does the number 6 in the part number indicate?
The 6 in the first block of the 3VA6115-6HN31-0AA0 catalog number designates it as an H-Class (High Breaking Capacity) breaker. This correlates to its interrupting ratings of 65kA at 480V and 100kA at 240V.
What is the adjustment range for the continuous current (Ir) on this breaker?
The ETU350 trip unit on this 150A frame breaker features an adjustable long-time pickup (Ir). The continuous current setting can be dialed down from the maximum 150A rating to a minimum of 60A.
Does the LSI function allow for selective coordination with downstream breakers?
Yes, the LSI trip unit allows you to adjust both the short-time pickup (Isd) and the instantaneous pickup (Ii). This flexibility enables engineers to optimize selective coordination with downstream circuit breakers and protect specific motor or equipment loads.
Is the 3VA6115-6HN31-0AA0 approved for commercial HVAC equipment?
Yes, this circuit breaker carries a HACR (Heating, Air Conditioning, and Refrigeration) rating. It is heavily tested and certified to handle the significant inrush currents generated by HVAC compressors and blower motors.
Can the terminal configuration on the 3VA6115-6HN31-0AA0 be modified for different conductors?
Yes, while the breaker supports lug connections, it accepts a variety of interchangeable AL or CU lug kits. This allows installers to safely terminate different wire gauges or utilize multi-conductor setups depending on the electrical service.
Can the 3VA6115-6HN31-0AA0 be reverse fed in a panel?
Yes, this molded case circuit breaker is designed to allow reverse feeding. This provides additional wiring flexibility for panel builders and electricians when routing line and load conductors in constrained enclosures.
