The EHD3030 molded case circuit breaker is part of the Eaton Cutler-Hammer Series C line, suitable for diverse applications. Rated at 30 amperes, this device operates effectively within specified frequency limits of 50 to 60 Hz. It features three poles to facilitate three-phase connections.
For reliability during fault conditions, the EHD3030 is rated for interrupt capacities of 14 kAIC at 480 VAC and 18 kAIC at 240 VAC, making it a robust choice for protecting circuits. The breaker’s operating temperature ranges from a minimum of 0°C to a maximum of 40°C, allowing it to function in standard conditions. Additionally, it can be stored safely within a temperature range not exceeding 40°C, with a maximum humidity level of 80% for both operation and storage conditions, without condensation issues.
It operates effectively at altitudes up to 1000 meters above sea level, providing versatility across multiple installations. The trip function incorporates fixed thermal and fixed magnetic mechanisms to enhance circuit protection. The EHD3030 is built with frame size classified as Frame F, solidifying its structural attributes for reliable performance.
