Information About BF120H
The BF120H is part of the Siemens BL Series of thermal-magnetic molded case circuit breakers, engineered for panelboard mounting and long-term service reliability. It incorporates LI trip functions (long-time and instantaneous) for precise fault response and a built-in GFCI mechanism to protect personnel and equipment from ground fault currents. The breaker’s bolt-on mounting system ensures secure installation, while compliance with UL, CSA, and NOM standards guarantees global compatibility. Its durable construction and efficient thermal-magnetic protection make it suitable for both new installations and retrofit applications.
Key Features:
- Rated Current: 20A current rating supports general-purpose circuit protection.
- Voltage Rating: Operates at 120 VAC for standard residential and commercial systems.
- Interrupting Capacity: 22 kAIC at 120V for reliable fault interruption under load.
- Ground Fault Protection: Integrated GFCI safeguards equipment and personnel from leakage currents.
- Trip Functionality: Long-time and instantaneous (LI) trip curve ensures optimal protection response.
- Mounting Style: Bolt-on design provides secure and vibration-resistant installation.
- Terminal Compatibility: Accepts wire sizes from 10 AWG to 14 AWG for flexible wiring options.
- Safety Certifications: UL, CSA, and NOM approved for use in compliant electrical systems.
The BF120H delivers the reliability and precision required for safe and efficient ground fault protection in low-voltage electrical installations.
