3VF6111-6EL74-0AP1 SIEMENS

The 3VF6111-6EL74-0AP1 is a robust 3-pole circuit breaker designed by Siemens for comprehensive motor protection. It features an adjustable overcurrent release within the range of 250-500A (IR), providing flexibility for various motor applications. This circuit breaker boasts a high interrupting capacity (ICU) of 65kA at 415V, ensuring reliable performance under fault conditions. An integrated N-relay with a fixed setting of 15 times the rated current (15 x IN) enhances protection against neutral faults. The fixed-mounted design simplifies installation, while the adjustable trip class allows for fine-tuning the tripping characteristics to match specific motor requirements. Phase-failure sensitivity is incorporated to prevent damage from unbalanced voltage conditions. This model comes without an auxiliary release but includes two auxiliary switches and one alarm switch for comprehensive monitoring and control. The inclusion of connecting leads facilitates easy integration into existing electrical systems. This circuit breaker provides reliable and adaptable motor protection.
