Graco 121623 Circuit Breaker – 10 A, 2-Pole
The Graco 121623 Circuit Brkr 10A 2P is a compact, industrial-grade protective device designed to safeguard your airless sprayer systems and high-pressure fluid circuits. With its two-pole design and 10-amp rating, it delivers balanced power distribution and reliable protection against overcurrent faults.
Key Features
- 10 A rating: Provides robust overload protection for motors, pumps, and solenoids.
- Two-pole configuration: Isolates both live wires simultaneously for enhanced safety.
- Compact footprint: Dimensions of approximately 3.6″ (L) × 1.2″ (H) × 1.2″ (W) make it easy to mount in tight control panels. :contentReference[oaicite:0]{index=0}
- Thermal-magnetic trip mechanism: Combines time-delay for startup inrush and instant short-circuit response. :contentReference[oaicite:1]{index=1}
- Durable housing: Made from UV- and chemical-resistant polycarbonate for long life in harsh environments. :contentReference[oaicite:2]{index=2}

Why Choose the 121623 Breaker?
When building or servicing high-performance coating rigs, electrician panels or OEM control systems, circuit protection is often overlooked. The 121623 breaker offers a tight package, reliable trip characteristics, and long-term durability — making it a wise choice for professional setups.
Installation & Maintenance Tips
- Mount on a DIN-style rail or secure flat-panel surface—its low profile helps save space.
- Wire with appropriately rated conductors; ensure both poles are isolated equally.
- Perform manual trip tests during scheduled maintenance to verify the reset lever is functioning.
- Inspect for visual signs of wear, corrosion or housing damage every 6 months.
Frequently Asked Questions
A two-pole (2P) circuit breaker interrupts both live conductors simultaneously. This ensures complete isolation of the circuit, which is important for systems using split-phase or dual-phase AC, common in industrial power panels.
It's not recommended to change the amp rating arbitrarily. A lower-amp breaker may nuisance-trip under normal load, while a higher-amp version may not protect your equipment against overload properly. Always conform to the design specifications in your machine’s manual or consult an electrical engineer.
Test the reset lever manually during regular maintenance (e.g., quarterly or semi-annually). If the breaker fails to trip when tested or shows signs of damage, it should be replaced. The device is rated for over 10,000 mechanical operations under normal conditions. :contentReference[oaicite:8]{index=8}
Yes — electrically, the 121623 is a standard-rated 10 A, 2-pole breaker. As long as your non-Graco system uses a compatible voltage and current profile, it may work. However, make sure mounting, wiring, and style (manual reset, trip curve) suit your design, and verify that it meets your panel’s safety standards.
