Information About Q21520CT
The Q21520CT is part of Siemens’ QT series of miniature molded case circuit breakers, engineered for space-efficient residential load center applications. The quadplex design enables multiple circuit protections within a single breaker footprint, supporting efficient panel layouts. This breaker integrates using a plug-in mounting method compatible with Siemens load centers and operates with a thermal-magnetic trip system to address overload and short-circuit conditions. Typical usage includes residential service panels where circuit density, standardized installation, and reliable protection are required.
Key Features:
- QT series quadplex design: Allows multiple circuits within a compact breaker format.
- 15/20 amp ratings: Supports mixed residential branch circuit requirements.
- Two-pole configuration: Designed for 120/240V single-phase systems.
- Thermal-magnetic trip unit: Provides long-time and instantaneous protection.
- 10 AIC interrupt rating: Suitable for standard residential fault levels.
- Plug-in mounting: Enables quick installation in compatible Siemens load centers.
- Space-saving construction: Optimizes panel capacity without additional enclosures.
The Q21520CT delivers the reliability and precision required for residential load centers requiring compact, multi-circuit overcurrent protection.
