Siemens ED61B030 - 30 A, 600 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens ED61B030, a 1-pole, 30A molded-case circuit breaker built for dependable protection in panelboards and load centers. With a bolt-on mounting design and a thermal-magnetic trip unit, this breaker delivers stable, repeatable protection for branch circuits in commercial, residential used? No—this is intended for environments where reliability matters, including light industrial applications.

Why this breaker stands out

• Secure bolt-on mounting ensures a rigid, vibration-resistant bus connection. That means fewer discussions about loose connections and longer-term reliability in cabinets that experience movement or vibration.
• Thermal-magnetic trip unit provides precise, predictable protection. The thermal element handles overcurrent slowly, while the magnetic element responds quickly to short-circuits, reducing nuisance trips and safeguarding delicate equipment.
• 1-pole design for single-phase circuits: ideal for branch circuits within panelboards and load centers where space and simplicity matter.
• 600V rating supports industrial and commercial applications, expanding how and where you can safely deploy this breaker.
• OEM-compatible performance tuned to work seamlessly with Siemens panelboards and other compatible load centers—streamlining replacement and upgrades.
• Versatile application suitable for residential-style projects that require robust protection in commercial or light industrial environments, such as lighting, receptacle, and control circuits.

Practical use cases

Use the ED61B030 to protect a dedicated 30A branch circuit in Siemens panelboards or matching load centers. It’s well-suited for:

• Commercial electrical rooms where a reliable 30A circuit breaker is needed for HVAC controls, lighting feeders, or small machinery.
• Retrofits or replacements in existing Siemens panels, ensuring compatibility and straightforward installation with bolt-on mounting.
• New installations in light industrial settings where robust current protection and quick fault interruption are essential.
