Reliable Protection for Industrial Electrical Systems
Miniature circuit breakers automatically disconnect electrical circuits when overload or short circuit conditions occur, protecting wiring, motors and connected equipment from electrical damage. The thermal element responds to sustained overload conditions, while the magnetic element provides rapid operation during severe fault conditions.
The IMO UB10D3063A features a D curve tripping characteristic that allows higher temporary inrush currents before magnetic tripping occurs, making it ideal for industrial motors, transformers and other inductive equipment while maintaining dependable protection against genuine electrical faults.
