HMA3450 - 450Amp Circuit Breaker Description
HMA3450 - 450Amp Circuit Breaker
The HMA3450 is a 450-amp, 3-pole thermal-magnetic circuit breaker designed for electrical equipment that uses the HMA breaker configuration. When you're replacing a breaker in an existing system, the important part is making sure the new unit matches the original specifications.
Key Features and Benefits
- 450 Amp, 3-pole configuration for compatible HMA applications
- Thermal magnetic circuit breaker design
- Interchangeable trip unit for matching equipment requirements
- 40°C rated
- Load-side terminals included
- Defined dimensions make it easier to confirm physical compatibility
- Suitable for maintenance and replacement projects involving existing HMA breaker systems
- Designed for form, fit, and functional replacement rather than changing the original equipment setup

Material Compliance and Certifications
Specific material compliance information, certifications, and agency listings were not provided for the HMA3450. UL, CSA, RoHS, or other certification claims should not be assumed without verification.
If a project requires a specific listing or compliance standard, confirm the breaker markings and check the applicable equipment documentation before installation.
Where It Works Best
The HMA3450 450 Amp circuit breaker is best suited for existing electrical equipment that requires an HMA-type, 3-pole thermal magnetic breaker with matching electrical and physical specifications. It is especially useful for maintenance applications where the goal is to replace a breaker while keeping the existing system arrangement unchanged.
For replacement work, the amp rating is only one part of the match. Check the existing equipment for the correct HMA type, pole configuration, voltage, A.I.C. rating, trip unit style, dimensions, and terminal requirements.
