Reliable Protection for High-Inrush Industrial Loads
Miniature circuit breakers disconnect electrical circuits automatically whenever overload or short-circuit conditions occur, protecting wiring, equipment and connected loads while improving the overall safety and reliability of electrical installations.
The D curve characteristic allows substantially higher temporary inrush currents before magnetic tripping occurs, making the P1MB3PD32 particularly suitable for transformers, motors, contactors, industrial power supplies and other inductive equipment commonly found in industrial automation systems.
Typical Applications
- Industrial control panels.
- Motor control centres.
- Transformer protection circuits.
- Industrial automation equipment.
- OEM machinery.
- Commercial three-phase distribution boards.
