3VA5210-1BB61-0AA0 SIEMENS

The 3VA5210-1BB61-0AA0 is a molded case circuit breaker (MCCB) from Siemens, designed for robust circuit protection in industrial and commercial applications. This 3VA5 UL frame circuit breaker has a frame size of 250, indicating its capacity to handle substantial current loads. It features a 2-pole configuration, making it suitable for single-phase systems. With a maximum short-circuit breaking capacity (Icu) of 100kA at 480V, it ensures reliable protection against high-fault currents. Specifically designed for line protection, this MCCB is equipped with an MCS110 trip unit. The rated current (In) is 100A, optimized for circuits with corresponding current demands. This particular model does not include overload protection, focusing solely on short-circuit protection. The self-protection feature is set at Ii=16 x In, providing instantaneous tripping at 16 times the rated current. Note that this circuit breaker is supplied without connection terminals, allowing for flexible installation options based on specific application requirements. This MCCB is ideal for applications where fast and reliable short-circuit protection is paramount.
