PDG21M0150TFFJ - 150 Amp Circuit Breaker

PDG21M0150TFFJ - 150 Amp Circuit Breaker

When you're matching a breaker to an existing electrical system, the details matter. The Eaton PDG21M0150TFFJ is a Power Defense Frame 2 molded-case circuit breaker rated at 150 amps with a single-pole configuration. It has an interrupting rating of 65 kA at 277 VAC, providing the capacity required for compatible commercial and industrial applications where higher fault currents may be present. This breaker uses a fixed-trip design and comes with line and load lugs, keeping the configuration straightforward for applications that require these features. At 1.38 inches high, 6 inches wide, and 3.5 inches deep, it also packs its electrical capabilities into a relatively compact footprint. For maintenance work, equipment replacement, or a new installation, the PDG21M0150TFFJ is a practical choice when your system specifications call for this exact combination of amperage, poles, interrupting capacity, and connections.

Key Features and Benefits

• 150-amp rating for compatible commercial and industrial electrical applications.
• Single-pole configuration for systems requiring 1-pole circuit protection.
• 65kA interrupting capacity at 277 VAC for applications with substantial available fault current.
• Fixed trip design provides predetermined trip characteristics without field adjustment.
• Line and load lugs provide connection points on both sides of the breaker.
• Power Defense Frame 2 design combines circuit protection with a compact physical profile.
• Globally rated Power Defense platform designed for a broad range of electrical distribution applications.
• Clearly defined ratings make it easier to compare the breaker with the requirements of an existing system or planned installation.

Material Compliance and Certifications

• The Power Defense molded case circuit breaker family is designed to meet recognized electrical performance and safety requirements. Depending on the specific configuration, products within the Power Defense Frame 2 family may carry applicable UL, CSA, IEC, CCC, and RoHS compliance or certification markings.
• For jobs where a specific approval or material compliance standard is required, check the markings on the breaker and the applicable manufacturer documentation for the PDG21M0150TFFJ before installation. This is especially important when equipment specifications, local codes, or project requirements call for a particular certification.
  

Where It Works Best

• The PDG21M0150TFFJ makes sense in compatible commercial and industrial power distribution systems that specifically require 150A, single-pole protection and a 65kA interrupting rating at 277 VAC. It may be used in electrical distribution equipment, facility power systems, equipment protection applications, and compatible panel or switchboard installations where its electrical and physical specifications are a match.
  
• It can also be a practical replacement option when maintaining existing equipment. In that situation, don't rely on amperage alone. Check the PDG21M0150TFFJ part number, pole count, voltage, interrupting rating, trip type, lug arrangement, dimensions, and equipment requirements. Getting those details right is far more important than simply finding another breaker marked "150A."
