Description
Designed for the 3VA5 frame, this 3-pole molded case circuit breaker provides robust LI protection for industrial applications. It is equipped with a TM240 thermal-magnetic trip unit, allowing users to adjust both thermal (245-350A) and magnetic parameters. The unit installs into Siemens panelboards and switchboards, and replaces older HJD63B350 breakers when used with a mounting kit. Rated 65kAIC at 480VAC, this Class H breaker is HACR rated and current limiting.Specifications

Product FAQs
7 answersWhich legacy Siemens breakers does the 3VA5335-6EF31-0AA0 replace?
This 3VA53 frame breaker replaces legacy 350A JD-frame breakers, such as the HJD63B350. When upgrading an existing panelboard or switchboard from a JD-frame to this 3VA model, a specific retrofit mounting kit is required.
What panelboards are compatible with this 3VA53 frame breaker?
The 3VA5335-6EF31-0AA0 is designed for use in Siemens P1, P2, P3, P4, and P5 panelboards, as well as Siemens switchboards. Proper installation requires the corresponding strap kit or mounting hardware for your specific panel type.
Are terminal lugs included with the 3VA5335-6EF31-0AA0?
No, the -0AA0 catalog suffix indicates that this circuit breaker is shipped without terminal lugs. Line and load lugs must be sourced separately based on your required wire gauge and conductor material.
What is the thermal adjustment range for this 350A breaker?
This breaker is equipped with a TM240 thermal-magnetic trip unit that allows the continuous current (thermal) protection to be adjusted from 245A to 350A. The magnetic instantaneous trip is also fully adjustable for precise coordination.
Can the 3VA5335-6EF31-0AA0 be reverse fed?
Yes, this thermal-magnetic molded case circuit breaker is reverse feed capable. It can be safely wired with the incoming power connected to either the top or bottom terminals without affecting its protective functions.
Is this 350A breaker suitable for HVAC equipment?
Yes, it is HACR rated, meaning it is tested and approved for the specific inrush currents and operational demands of heating, air conditioning, and refrigeration systems.
Is the 3VA5335-6EF31-0AA0 a current-limiting circuit breaker?
Yes, this breaker features a current-limiting design. During a high-level short circuit, it clears the fault rapidly to reduce the peak let-through current and energy, providing enhanced protection for downstream equipment.
