Reliable Protection for Three-Phase Electrical Circuits
The IMO BR6D3N20A automatically disconnects the circuit when overload or short circuit conditions are detected. Its D curve characteristic allows it to tolerate higher start-up currents before tripping, making it suitable for circuits feeding motors, transformers and equipment with significant inrush demand.
Its 3 pole plus neutral arrangement makes it suitable for three-phase installations where the neutral conductor must be switched alongside the live phases. This makes the BR6D3N20A a practical choice for panel builders, electrical contractors and maintenance engineers requiring reliable multi-pole circuit protection.
Typical Applications
- Three-phase distribution boards.
- Industrial control panels.
- Motor control circuits.
- Transformer protection circuits.
- OEM machinery and automation equipment.
- Commercial and industrial electrical installations.
