HLB3300 - 300Amp Circuit Breaker

HLB3300 - 300Amp Circuit Breaker

The HLB3300 is a 3-pole, 300-amp thermal magnetic circuit breaker designed for use in compatible HLB electrical systems. It's commonly selected for commercial and industrial environments where keeping existing equipment in service is the priority. When you're working within 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 HLB frame style.

Material Compliance and Certifications

The HLB3300 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 HLB3300 is best suited to commercial buildings, industrial facilities, and maintenance environments where HLB-compatible equipment is already in place. It's commonly used when replacing an existing breaker and keeping the original panel layout unchanged is important.
