3VL2706-2EM43-0AA0 SIEMENS

The 3VL2706-2EM43-0AA0 is a robust 4-pole circuit breaker from Siemens, designed for line protection in electrical systems. It falls under the VL160H series, known for its high breaking capacity, ensuring reliable performance under demanding conditions. This circuit breaker boasts an Icu (ultimate short-circuit breaking capacity) of 70kA at 415V AC, providing effective protection against high-level fault currents. Equipped with an Electronic Trip Unit TM, it offers precise and adjustable protection characteristics. The In (rated current) is 63A, while the IR (rated current setting range) can be adjusted from 50A to 63A for overload protection. The II (instantaneous tripping current) is adjustable from 300A to 600A, providing short-circuit protection. Notably, this model does not include N (neutral) protection, catering to specific circuit configurations. It also lacks auxiliary release mechanisms and auxiliary/alarm switches, simplifying its design and application. This circuit breaker is well-suited for applications requiring reliable and adjustable overcurrent and short-circuit protection without the need for additional signaling or control features.
