The Clipsal MX9MN320 is a 20A miniature circuit breaker (MCB) with a 3P+N configuration, designed for 415V three-phase circuit protection in commercial and industrial environments. It uses a C curve tripping profile (5 to 10 times rated current), ideal for circuits with moderate inrush loads such as HVAC units, lighting arrays and small motors.
With a 6kA breaking capacity, the MX9MN320 meets AS/NZS 60898 compliance requirements. It features a toggle actuator, contact position indicator, and clear ON/OFF status display for safe operation. Designed for durability, it is rated for 20,000 electrical and mechanical cycles and includes IP20 internal protection.
The 54mm housing fits standard DIN rail boards, and tunnel-type terminals accept 1 to 10mm² flexible and 1 to 16mm² rigid cables. It is also fully MAXBAR compatible for streamlined busbar integration in MAX9 setups.
