Siemens 3VA5180-6EC31-0AA0 Molded Case Circuit Breaker

This breaker is designed for installation in Siemens P2 and P3 panelboards, as well as compatible switchboards and enclosures. Specific mounting hardware or nut keepers may be required depending on the panelboard configuration.

The LI designation means the breaker provides Long-Time (thermal) and Instantaneous (magnetic) trip functions. The long-time function protects against sustained overloads, while the instantaneous function clears severe short circuits immediately.

Yes, it features a TM230 thermal-magnetic trip unit with a fixed thermal setting (Ir) at 80A and an adjustable magnetic instantaneous setting (Ii). This allows electricians to fine-tune the short-circuit response based on the specific load requirements.

This breaker belongs to the Siemens 3VA51 frame class, which has a maximum continuous current rating of 125A. This compact frame size is designed to save space in high-density panelboards.

Yes, this breaker is rated for DC applications up to 500VDC, providing an interrupting capacity of 100kA at 500VDC. When used in DC systems, specific pole wiring configurations are required per Siemens installation guidelines.

Yes, Siemens 3VA5 thermal-magnetic circuit breakers are UL listed for reverse-feed installations, allowing flexibility in panelboard wiring and main breaker applications.

Yes, Siemens 3VA5 molded case circuit breakers are HACR rated, making them suitable for protecting heating, air conditioning, and refrigeration equipment circuits.
