E43B015 - 15Amp Circuit Breaker

E43B015 - 15 Amp Circuit Breaker

The E43B015 molded case circuit breaker is a 3-pole, 15-amp thermal magnetic breaker designed for dependable circuit protection in commercial and industrial electrical distribution systems. Built on the E43 frame, this breaker helps protect wiring and connected equipment from overloads and short circuits while maintaining compatibility with panelboards and switchboards that require this specific form and fit. With interrupting ratings of 18kA at 480VAC and 25kA at 240VAC, the E43B015 is suitable for installations where consistent protection and proper system coordination are essential. Its bolt-on mounting design provides secure installation in compatible panels, and included load-side terminals help streamline wiring during maintenance or replacement projects. Rated for 40°C environments and HACR applications, this molded case circuit breaker is commonly used in legacy systems where maintaining original specifications and electrical ratings is important. Built with durable internal components, these breakers are designed for long service life when used within their intended electrical parameters.

Where It Works Best

• The E43B015 3-pole 15A circuit breaker is well suited for electrical systems that require the E43 frame bolt-on configuration, particularly in existing panelboards and switchboards designed for this breaker type.
• Typical applications include:
• Commercial building electrical distribution panels
• Industrial control panels and equipment feeders
• HVAC branch circuits where HACR-rated breakers are specified
• Maintenance and replacement projects in facilities operating legacy electrical equipment
• Three-phase branch circuit protection in manufacturing or service environments
• Because electrical systems often depend on specific frame sizes and mounting styles, the E43B015 helps maintain form, fit, and functional compatibility when servicing or replacing breakers in established installations.
