Siemens 3VA6340-7HL31-0AA0 400 Amp 3-Pole Molded Case Circuit Breaker – Panel Mount – 240/480/600VAC Rated

The Siemens 3VA6340-7HL31-0AA0 is a high-performance molded case circuit breaker (MCCB) from the SENTRON 3VA6 series, engineered for industrial, commercial, and high-energy power distribution systems requiring very high interrupting capacity. Built on the 3VA63 frame, this 400A, 3-pole breaker provides reliable long-time and instantaneous (LI) protection using an ETU320 electronic trip unit with adjustable settings for precise coordination. It is designed for integration into Siemens P3, P4, and P5 panelboards, switchboards, and motor control centers. With a high interrupting rating of up to 100kA at 480VAC, it ensures strong fault protection in critical electrical networks.
