Eaton PDG21M0150TFFJ - Circuit Breaker | AmpState

Meet the Eaton PDG21M0150TFFJ molded case circuit breaker, a dependable solution for protecting branch circuits in panelboards and load centers. Available through AmpState, this unit is engineered to deliver reliable overcurrent and short-circuit protection where it matters most.

• Compact molded case design maximizes panel space and simplifies installation in tight or crowded panels, helping you fit more circuits without sacrificing accessibility or organization.
• Thermal-magnetic trip unit provides stable, repeatable protection. The thermal element responds to overloads for controlled, predictable trips, while the magnetic element delivers instantaneous action on high-energy short circuits.
• OEM-compatible construction is designed to align with matching Eaton OEM load centers and panelboards, ensuring straightforward replacements and minimal retrofit adjustments.
• Versatile for multiple sector needs suitable for residential, commercial, and light industrial applications, delivering consistent performance across a range of environments.

What it is and how it works

The PDG21M0150TFFJ is a thermal-magnetic molded case circuit breaker that interrupts current during overcurrent and short-circuit events. In normal operation, it passes current with low resistance. When abnormal conditions occur, the thermal sensor detects excess heat from overloads and the magnetic mechanism can trip instantly for short circuits, interrupting the circuit to protect wiring and connected devices.

Where and how to use

Ideal for upgrading or replacing breakers in existing panelboards and load centers where Eaton compatibility matters. It slots into panels built to Eaton’s molded case breaker standards, reducing replacement hassles and preserving panel layout and bus connectivity.
