Information About QSA2020SPD
The QSA2020SPD is a surge protection circuit breaker engineered by Siemens for use in designated residential load centers. It combines branch circuit overcurrent protection with integrated surge suppression to reduce the impact of transient voltage spikes on connected equipment. The device is designed for plug-in installation and operates within single-phase 240-volt systems. It is commonly installed in Siemens EQ-family panels where coordinated surge and circuit protection is required in residential electrical distributions.
Key Features
- Integrated surge protection: Provides suppression of transient voltage surges directly at the panel level.
- Dual 20-amp breaker design: Combines surge protection with branch circuit overcurrent protection.
- Thermal-magnetic LI trip function: Responds to sustained overloads and instantaneous short-circuit faults.
- 10 kA interrupting capacity: Ensures reliable fault interruption at rated system voltage.
- Plug-in mounting: Enables fast installation in compatible Siemens residential panels.
- Panel compatibility: Designed exclusively for Siemens EQ, EQL, SEQ, EQG, PL, and ES load centers.
- Residential application focus: Optimized for home electrical systems requiring enhanced surge defense.
The QSA2020SPD delivers the reliability and precision required for combined surge and overcurrent protection in Siemens residential electrical distribution panels.
