Request a... Price & Availability It is part of Siemens' extensive family of circuit breakers known for their robust construction and precise tripping characteristics. The DB-11 features a thermal-magnetic trip mechanism, providing both overload and short-circuit protection. With a frame size rated for 100A, it is suitable for branch circuit protection in motor control centers, panelboards, and distribution systems. The breaker is UL489 listed and meets international standards, ensuring safe operation in various environments. This circuit breaker has a voltage rating of 480V AC and an interrupting capacity of 14kA at 480V, making it adequate for many industrial applications. The DB-11 is a 3-pole unit, offering three-phase protection. Its compact design allows for easy installation in standard Siemens panelboards and switchboards. The thermal element is adjustable, allowing users to set the overload trip delay according to specific load requirements. The magnetic element provides instantaneous tripping on high faults, protecting downstream equipment from damage. The DB-11 is an original Siemens product, manufactured to the highest quality standards. It is commonly used in manufacturing plants, water treatment facilities, and commercial buildings. As a replacement part, it is compatible with Siemens load centers and distribution panels that accept DB series breakers. Its proven reliability and long service life make it a preferred choice for maintenance and upgrade projects. Whether for new installations or retrofits, the Siemens DB-11 ensures dependable circuit protection. The Siemens DB-11 is a molded case circuit breaker (MCCB) designed for industrial and commercial applications requiring reliable overcurrent protection. Basic Product Information 3-pole design for three-phase applications 480V AC voltage rating with 14kA interrupting capacity Compact molded case construction for easy mounting UL489 and CSA certified for North American installations Adjustable thermal trip setting for flexibility Thermal-magnetic trip mechanism for overload and short-circuit protection Technical Specifications Version & Model Difference The Siemens DB-11 is part of the DB series, which includes various frame sizes and pole configurations. The DB-11 specifically denotes a 100A, 3-pole breaker. Other versions in the series include DB-1 (100A, 1-pole), DB-2 (100A, 2-pole), and DB-3 (100A, 3-pole with different interrupting ratings). The DB-11 may have been superseded by newer Siemens breakers like the ED or JD series, but it remains a common replacement part for existing installations. Always verify the exact specifications and compatibility with your panel before ordering. Application Scenarios Is the DB-11 a thermal-magnetic breaker?
