CHH2150H4 - 150Amp Circuit Breaker

CHH2150H4 - 150Amp Circuit Breaker

The CHH2150H4 is a 150 Amp, 2-pole molded case circuit breaker commonly found in commercial and industrial electrical equipment where a CHH4-series breaker was originally specified. You'll often see this breaker installed in switchboards, panelboards, feeder circuits, and distribution equipment that have been operating reliably for years.

When a breaker needs to be replaced, the goal is usually straightforward: find the same type, match the ratings, and keep the existing equipment configured the way it was designed.

The molded case construction is built to last, making it a practical choice for ongoing maintenance and repair work. For electricians, contractors, and facility personnel, the CHH2150H4 is often simply the breaker that's already in the system—and sometimes that's exactly what's needed.

Where It Works Best

• Commercial office buildings
• Manufacturing and industrial facilities
• Institutional and educational buildings
• Electrical distribution panels
• Switchboards and power distribution equipment
• Feeder circuit protection applications
• Branch circuit protection applications
• Existing CHH4-series installations
• Maintenance and repair projects requiring matching specifications
• Facilities operating long-standing electrical infrastructure
• Applications requiring 150 Amp, 2-pole circuit protection
• Systems requiring a 42kAIC interrupting rating at 240VAC

When a breaker in an existing CHH4 installation needs attention, replacing it with a breaker that matches the original specifications is often the simplest approach. The CHH2150H4 is commonly used for that purpose, helping facilities maintain consistency across their electrical systems while preserving the ratings, configuration, and layout of the original installation.
