Reliable Protection for Three-Phase Electrical Circuits

Miniature circuit breakers such as the IMO BR6C3N40A-L are designed to automatically disconnect a circuit when an overload or short circuit occurs. This helps protect cables, connected devices and electrical equipment from damage caused by excessive current.

The C curve characteristic makes this MCB well suited to circuits where a brief inrush current may occur during normal operation. This makes it a practical choice for machinery, control panels, lighting circuits, small motors and general three-phase distribution systems.

Typical Applications

• Industrial control panels and automation enclosures.
• Three-phase machinery circuits.
• Commercial distribution boards.
• Motor and transformer protection circuits.
• Lighting and power distribution systems.
• Panel building, maintenance and electrical installation work.
