Designed to safeguard feeder and control circuits, HVAC systems, and lighting loads, it supports 480 VAC operations and carries a 65 kAIC interrupt rating. This unit delivers reliable performance in demanding environments with a temperature tolerance from -25°C to 50°C. With its fixed thermal magnetic trip and current-limiting type, it provides fast, precise interruption of fault currents to protect downstream equipment. Key Features: Amperage: 30 A nominal current capacity suitable for light to medium-duty power distribution. Applications: Engineered for backfeeding, feeder circuits, control circuits, HVAC systems, HID lighting, and SWD-rated loads at 15 and 20 A. Frame: Built on a compact and robust D-frame architecture ideal for panel integration. Interrupt Rating: High fault-clearing capacity of 65 kAIC at 480Y/277 VAC ensures enhanced safety. Number of Poles: 3-pole configuration provides simultaneous protection across three conductors. Temperature Rating: Operational temperature range from -25°C to 50°C supports reliable performance in varied conditions. Trip Type: Fixed thermal magnetic trip unit for consistent overload and short-circuit protection. Type: Current-limiting breaker that minimizes let-through energy during fault conditions. Voltage: Rated for 480 VAC distribution systems in commercial and industrial setups. The 140UT-D7D3-C30 delivers high-interrupting performance and rugged reliability across a range of demanding electrical distribution environments.
