Information About B2020
The B2020 is a molded case circuit breaker from Siemens’ B Series engineered for dependable branch-circuit protection in 240-volt single-phase systems. Its B-frame construction provides strong mechanical durability, while the bolt-on connection ensures secure mounting and stable electrical contact within panelboards. The built-in thermal-magnetic trip mechanism delivers both long-time overload protection and instantaneous response to high-fault currents, supporting safe operation across a wide range of loads. With a 20-amp rating and a 10 kA interrupting capacity at 240 volts, the breaker provides effective fault clearing for residential and commercial installations requiring reliable two-pole protection.
Key Features
- 20-Amp Current Rating: Supports typical residential and commercial load demands while providing dependable branch-circuit protection.
- Thermal-Magnetic Trip Mechanism: Combines long-time overload sensing with instantaneous short-circuit response for comprehensive protection.
- Bolt-On Connection Style: Ensures secure mechanical fastening and stable electrical contact in compatible Siemens panelboards.
- Two-Pole Configuration: Delivers simultaneous protection across both legs of a 240-volt single-phase system.
- 10kA Interrupting Rating: Provides the capability to safely clear moderate fault currents, reducing damage to wiring and equipment.
- B Frame Durability: Engineered for long-term performance with robust mechanical construction suitable for diverse environments.
- Long-Time & Instantaneous Trip Functions: Supports selective coordination by responding effectively to both gradual overloads and sudden high-energy fault events.
- Compact Molded Case Design: Facilitates efficient installation in tight panel spaces while maintaining reliable electrical performance.
The B2020 delivers the reliability and precision required for protecting 240-volt single-phase electrical systems across residential and commercial environments.
