3VL5740-2EM46-0AA0 SIEMENS

The 3VL5740-2EM46-0AA0 is a high-performance molded case circuit breaker (MCCB) from Siemens, designed for robust line protection in industrial and commercial applications. This 4-pole circuit breaker is part of the VL series, known for its reliability and high breaking capacity. It offers a high breaking capacity (Icu) of 70kA at 415V AC, ensuring effective protection against short circuits and overloads. Equipped with a Thermal-Magnetic (TM) trip unit, it provides adjustable overload protection (IR) ranging from 320A to 400A. The instantaneous short-circuit protection (II) is also adjustable, ranging from 2000A to 4000A, allowing for precise coordination with downstream devices. This model features N-conductor protection (100%), enhancing safety and preventing damage from neutral faults. It is specifically designed for line protection applications. This circuit breaker does not include an auxiliary release, auxiliary switch or alarm switch. The rated current (In) is 400A, making it suitable for a wide range of applications requiring substantial current carrying capacity. Its robust design and adjustable protection settings make it a versatile solution for various electrical distribution systems.
