Information About B2125

The B2125 is a BL Series low-voltage circuit breaker developed for Siemens panelboard systems requiring bolt-on mounting. Its molded case design incorporates a fixed thermal magnetic trip unit that ensures predictable operation during overload and short-circuit conditions. The breaker integrates directly with BL-frame panels, providing secure electrical connections and mechanical stability. Typical applications include residential, commercial, and light industrial distribution panels where CSA and UL certified protection devices are required.

Key Features:

  • BL Series Compatibility: Designed specifically for Siemens BL-frame panelboards to ensure correct fit and electrical integration.
  • Thermal Magnetic Protection: Provides inverse-time overload protection and instantaneous short-circuit interruption.
  • 10 kA Interrupt Rating: Capable of safely clearing fault currents in low-voltage power systems.
  • Bolt-On Connection Method: Ensures reliable conductor termination with reduced contact resistance.
  • Two-Pole Configuration: Supports single-phase 120/240 VAC circuits with simultaneous disconnection.
  • Molded Case Construction: Enhances durability, insulation, and resistance to mechanical stress.
  • Panelboard Mounting Design: Allows straightforward installation and replacement within standard panels.

The B2125 delivers the reliability and precision required for protecting low-voltage branch circuits and power distribution equipment.
