Siemens 3RV2011-1JA10 - Circuit Breaker | AmpState

The Siemens 3RV2011-1JA10 molded case circuit breaker is built to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. With a compact molded case design and a thermal-magnetic trip unit, it provides stable, repeatable protection across varying loads and environments, making it a reliable choice for both new installations and panel upgrades.

Key features that matter in the real world

• Space-efficient, molded-case design: minimizes panel footprint and simplifies wiring in tight enclosures.
• Thermal-magnetic trip unit: combines thermal sensing for gradual overloads with magnetic trip for fast response to high fault currents, reducing nuisance trips while maintaining protection.
• OEM panel compatibility: designed to pair with matching Siemens OEM load centers and panelboards for a clean, code-compliant installation.
• Reliable branch circuit protection: protects individual circuits from overcurrent and short circuits, supporting safe electrical distribution in residential, commercial, and light industrial settings.

Technical snapshot

• Manufacturer: Siemens
• Part Number: 3RV2011-1JA10
• Type: Thermal-magnetic molded case circuit breaker
• Application: Branch circuit overcurrent and short-circuit protection

Ideal use cases

• Upgrading a home or apartment panel to add circuits or replace an aging breaker
• Equipping small commercial panels for lighting, receptacle, and equipment branches
• Providing robust protection for light industrial panels with compact form factor requirements
• Replacing a faulty breaker in Siemens OEM load centers to maintain system compatibility

Why the thermal-magnetic protection matters

Real-world electrical loads vary, so the thermal element handles gradual overloads while the magnetic element activates during short circuits. This yields predictable tripping, minimizes nuisance trips, and keeps critical circuits online during normal operation. The result is safer, more reliable electrical distribution with reduced maintenance and downtime.

Compatibility and installation tips: Use with matching Siemens OEM load centers and panelboards. Ensure the panel rating and interrupting capacity align with your system requirements. This model is ideal for residential, commercial, and light industrial applications where space is at a premium and reliable protection is essential.
