## Long description

Three-pole Siemens circuit breaker 8UC7222-3BB20 rated at 20 A provides overcurrent protection for three-phase electrical systems. The device is designed for installation in industrial and commercial distribution boards where secure interruption of load currents is required. Its compact modular design allows space-efficient mounting and straightforward replacement or maintenance while helping to protect conductors and connected equipment from overloads and short circuits.
Advantages
This three-pole circuit breaker offers coordinated tripping for three-phase protection, ensuring simultaneous disconnection of all poles under fault conditions. The compact, modular enclosure simplifies installation in standard DIN-rail switchgear and reduces the panel footprint. Robust internal contacts and a stable operating mechanism provide consistent performance and long-term mechanical reliability. The breaker’s rated 20 A current capacity makes it suitable for a range of low- to medium-load circuits.
Suitable for
Protection of three-phase feeders and branch circuits in industrial panels
Commercial building electrical distribution
Motors and equipment requiring coordinated three-pole disconnection
Replacement or upgrade of existing modular breakers in DIN-rail panels
Key specifications
Number of poles: 3 (three-pole)
Rated current: 20 A
Application: three-phase overcurrent and short-circuit protection
Mounting: DIN-rail modular housing for compact panel installation
Operating mechanism: manual toggle for ON/OFF and trip indication
Typical environments: industrial and commercial electrical distribution boards
How to use
Install the circuit breaker on a compatible DIN-rail inside a distribution board according to local electrical standards and wiring diagrams. Ensure supply and load conductors are correctly connected to the input and output terminals respectively, and tighten terminals to the manufacturer’s recommended torque. Verify the breaker is the correct rated current for the circuit and coordinate with upstream and downstream protective devices. After installation, switch the device to ON and check for proper operation; if the breaker trips immediately, isolate the circuit and inspect for faults or incorrect wiring.
Usage recommendations
Use this Siemens three-pole, 20 A breaker in applications with matching thermal and short-circuit requirements. Coordinate with mains protection and protective relays where needed, perform periodic visual inspections, and verify terminal tightness after initial operation. Follow local electrical codes for selection, installation, and maintenance to ensure safe and reliable protection of wiring and equipment.
