Siemens ED61B020L - 20 A, 600 V, 1-Pole Circuit Breaker | AmpState

Meet the Siemens ED61B020L, a 20A, 600V, 1-Pole molded case circuit breaker built to protect branch circuits in panelboards and load centers. This compact, purpose-built device delivers dependable overcurrent and short-circuit protection for a wide range of installations, from homes to light commercial spaces.

Why the ED61B020L stands out

• Compact molded case design maximizes usable panel space and simplifies integration in tight panels, helping you maintain clean, organized panel layouts.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining overload sensing (thermal) with short-circuit detection (magnetic). This dual action helps reduce nuisance trips and ensures prompt response when circuits demand it.
• 1-pole configuration is ideal for protecting individual branch circuits, such as lighting or receptacle runs, with a straightforward, reliable installation.
• 600V rated performance supports a broad range of applications, ensuring compatibility with modern electrical systems while maintaining robust protection standards.
• OEM and panelboard compatibility designed to work seamlessly with Siemens and compatible load centers, ensuring proper fit, mounting, and trip characteristics.
• Versatile for residential, commercial, and light industrial use—a dependable choice whether you’re upgrading an existing panel or configuring a new installation.

Performance you can trust

The ED61B020L is engineered to guard against two critical faults: overcurrent and short circuits. The thermal-magnetic trip mechanism ensures you get precise, predictable protection that aligns with typical electrical load patterns found in everyday environments. In practical terms, this means:

• Overload protection for sustained drawing above 20A
• Rapid interruption during a short-circuit, helping limit damage to wiring and connected equipment
• Consistent protection performance across varying ambient conditions and wiring configurations
