The Siemens 3VA5170-4ED31-0AA0 is a reliable molded case circuit breaker (MCCB) aimed at enhancing electrical safety. With a rated current of 70 A, it can manage voltages up to 690 V AC and 500 V DC, accommodating diverse application needs. The three-pole configuration provides scalability for various circuit designs.

Boasting significant interrupting ratings, this breaker is capable of handling 14 KAIC at 600Y/347 V and 25 KAIC at 480 V, addressing fault conditions effectively. The built-in thermal-magnetic trip unit (TM210) facilitates fixed overload protection at 70 A while also offering robust short-circuit protection, rated at 10 times the current.

This unit supports a frequency range of 50/60 Hz and is equipped with a rated insulation voltage of 800 V, making it suitable for high-voltage applications. The fixed mounting type ensures a secure installation, while the IP40 enclosure rating provides protection against solid objects, making it suitable for indoor environments.
