The Siemens SENTRON 3VA10203ED320AA0 MCCB is a high-performance molded case circuit breaker designed to provide dependable protection against overloads, short circuits, and electrical faults in industrial and commercial power distribution systems. As part of the trusted SENTRON 3VA series, this MCCB combines compact design, robust construction, and advanced protection technology to ensure reliable operation and enhanced electrical safety. The breaker features a 20A rated current, 3-pole configuration, and 25kA breaking capacity at 415V AC, making it suitable for a wide range of low-voltage distribution applications.
The 3VA10203ED320AA0 is equipped with a TM210 Thermal Magnetic Trip Unit utilizing FTFM (Fixed Thermal Fixed Magnetic) protection technology. This configuration provides fixed overload protection at 20A and fixed short-circuit protection at 16 × In (320A), ensuring rapid fault detection and reliable circuit interruption when abnormal electrical conditions occur.
Designed for line protection applications, the Siemens 3VA10203ED320AA0 continuously monitors current flow and automatically disconnects the circuit whenever overloads or short-circuit faults are detected. This helps protect motors, transformers, cables, switchgear assemblies, control panels, and other critical electrical assets from costly damage, reducing downtime and improving system reliability.
Built on the compact 3VA1 Frame 100 platform, this MCCB offers excellent mechanical endurance of up to 20,000 operating cycles and electrical endurance of up to 9,000 operating cycles at 415V AC. Its space-saving design allows seamless integration into LT panels, PCC panels, MCC panels, switchboards, distribution boards, motor control centers, and OEM equipment.
