HLA3300 - 300Amp Circuit Breaker

HLA3300 - 300Amp Circuit Breaker

The HLA3300 is a 3-pole, 300-amp thermal magnetic circuit breaker designed for use in compatible HLA electrical systems. It’s commonly selected for commercial and industrial environments where keeping existing equipment in service is the priority. When you're working with an established electrical setup, having a breaker that matches the original form, fit, and electrical ratings helps make maintenance and replacement work more straightforward.

This unit features an interchangeable trip design and includes load-side terminals, making it a practical choice for systems already built around the HLA frame style.

Material Compliance and Certifications

The HLA3300 should be installed in accordance with applicable electrical codes and the requirements of the system in which it is used. Always confirm voltage ratings, interrupt ratings, and compatibility before installation.

Where It Works Best

The HLA3300 is best suited for commercial buildings, industrial facilities, and maintenance environments where HLA-compatible equipment is already in place. It’s commonly used when replacing an existing breaker and keeping the original panel layout unchanged is important.
