Siemens 3VA9243-0JJ13 2A 3-Pole 3 V Circuit Breaker

Siemens 3VA9243-0JJ13 2A 3-Pole 3 V Circuit Breaker is a compact, reliability-first protection device designed for three-phase circuits in control panels and light-duty distribution setups. With a precise 2 A current rating and a triple-pole design, this breaker delivers balanced protection across all three phases, helping prevent overloads from propagating through your system while keeping downtime to a minimum.

• Three-pole protection: Protects all three phases simultaneously, reducing the risk of phase imbalance and ensuring coordinated shutdown during faults.
• 2 A trip rating: Specifically tuned for low-load, three-phase circuits where sensitive equipment requires dependable overcurrent protection without nuisance trips.
• Voltage rating of 3 V: Built to operate within its specified low-voltage window, providing clear protection boundaries for compatible systems.
• Part number clarity: 3VA9243-0JJ13 makes ordering, stocking, and cross-referencing straightforward for technicians and procurement teams.
• Siemens engineering promise: Designed to integrate with Siemens panel ecosystems, offering consistent performance and predictable behavior in demanding environments.

This model answers the real-world needs of engineers and technicians who build and maintain three-phase control and protection schemes. Ideal for applications where a compact, reliable three-pole breaker is required to safeguard low-current loads, control circuits, or auxiliary services within Siemens-enabled panels and enclosures.

Why choose this Siemens 3VA9243-0JJ13 over generic alternatives? Its dedicated three-pole architecture ensures synchronized interruption across all phases, minimizing the chance of partial faults and equipment damage. The 2 A rating is tailored for precise protection, enabling longer asset life for sensitive loads while preventing unnecessary interruptions. With its clear part-number identity, it simplifies maintenance, stocking, and future upgrades within a Siemens-driven electrical system.

Practical tips for use: verify compatibility with your panel or enclosure, ensure correct phase wiring to the three poles, and match the 2 A setting to the protected circuit’s continuous load plus any inrush considerations. Keep this unit on hand as a ready replacement part for Siemens-based installations to reduce downtime and maintain consistent protection across your three-phase network.
