Siemens 3RV2011-1KA10 - 5 A, 3-Pole Circuit Breaker | AmpState

Introducing the Siemens 3RV2011-1KA10 — a compact 5 A, 3-pole molded case circuit breaker built to safeguard branch circuits in panelboards and load centers. Designed for dependable overcurrent and short-circuit protection, it pairs seamlessly with matching Siemens OEM panels to deliver consistent, long‑lasting performance.

• Space‑efficient molded case design: minimizes footprint to maximize panel real estate, making room for wiring and additional breakers without compromising protection.
• Thermal‑magnetic trip unit: combines thermal overload sensing with magnetic instantaneous trip for stable, repeatable protection against both gradual overcurrent and sudden short circuits.
• 3-pole configuration: protects all three hot legs in 3‑phase installations, ensuring coordinated protection across the circuit.
• OEM‑compatible: engineered to fit and operate with matching Siemens load centers and panelboards for a reliable, drop‑in replacement experience.
• Versatile across environments: ideal for residential, commercial, and light industrial applications—from home subpanels to small business electrical distributions.

Technical snapshot

• Manufacturer: Siemens
• Part Number: 3RV2011-1KA10
• Type: Thermal‑magnetic molded case circuit breaker
• Amperage Rating: 5 A
• Number of Poles: 3
• Application: Branch circuit overcurrent and short-circuit protection

Use cases and practical considerations: In a residential subpanel distributing lighting and outlets, this 5 A, 3‑pole breaker offers targeted protection for multiple legs in a three‑phase capable setup or for multi‑wire circuits in compatible panels. When replacing an existing unit, verify that the panelboard supports molded case breakers and that the replacement part number matches your Siemens model to preserve coordinated protection and precise trip characteristics. Installations should conform to local electrical codes and be performed by a qualified electrician.
