The ABB UF B700 A01 HIET404238R0001 is a high-performance product in ABB’s miniature circuit breaker series,designed for residential,industrial,and commercial applications.It provides reliable overload and short-circuit protection and complies with international standards IEC/EN 60898 and IEC/EN 60947-212.
1.Product Overview and Core Functions
Basic Positioning:The UF B700 A01 is a high-end model in ABB’s miniature circuit breaker(MCB)series,suitable for electrical protection scenarios requiring high breaking capacity and special functions.
Main Functions:
Overload Protection:Achieved through a bimetallic strip device,automatically disconnecting the circuit when the current exceeds the set value.
Short Circuit Protection:Employs electromagnetic trip technology,rapidly cutting off power in the event of a short circuit.
Isolation Function:Features a manually operated switch,usable as a circuit isolation device.
High Reliability:Utilizes a double insulation structure and metal operating mechanism,ensuring long-term stable operation.
2.Technical Specifications and Performance Parameters
Electrical Characteristics:
Breaking Capacity:Up to 25kA,suitable for high short-circuit currents that may occur in industrial and commercial environments.
Current Rating:Covers an operating current range of 1-1000A,meeting various application needs.
Protection Characteristics:Provides B,C,and D type trip characteristics for precise protection against different load types.
Compliance Standards:Strictly compliant with IEC/EN 60898 and IEC/EN 60947-2 International Standard
Physical Characteristics:
Structural Design:Utilizes a thermosetting material shell;when exposed to open flame,it will only gradually carbonize without melting or deforming.
Operating Mechanism:Independent metal operating mechanism,eliminating the need for a shell for positioning,improving structural stability and reliability.
Wiring Method:Both top and bottom can be used as cable entry points,supporting wire and busbar connections.
