Information About MBKQJ1225
The MBKQJ1225 is a Siemens MBK series main breaker and sub-feed panelboard kit developed for single-phase 240VAC electrical distribution applications. Designed for use with Siemens P1 panelboards, the assembly incorporates a 2-pole thermal magnetic circuit breaker with fixed long-time and instantaneous trip protection characteristics. The breaker supports conductor sizes ranging from 6 AWG to 300 kcmil copper and 4 AWG to 300 kcmil aluminum, providing installation flexibility in commercial and industrial feeder systems. Built to UL 489 and CSA C22.2 standards, the kit supports dependable overcurrent protection and structured panelboard distribution integration.
Key Features:
- 225A Current Rating: Designed for medium-capacity feeder and panelboard distribution applications.
- 2-Pole Breaker Configuration: Supports single-phase 240VAC electrical systems.
- Thermal Magnetic Protection: Combines overload and short-circuit protection functionality.
- Bolt-On Mounting Design: Provides secure breaker installation within Siemens P1 panelboards.
- LI Trip Functionality: Features long-time and instantaneous trip protection characteristics.
- Wide Wire Compatibility: Supports copper and aluminum conductors up to 300 kcmil.
- Included Installation Components: Supplied with mounting hardware, breaker, and lugs.
- UL and CSA Approved: Manufactured to UL 489 and CSA C22.2 certification standards.
The MBKQJ1225 delivers the reliability and precision required for panelboard feeder protection and commercial electrical distribution applications.
