Why it Matters

Protects all three phases together.
The MSN363 is a 63A three-pole miniature circuit breaker, the top of Hager's 3-pole MSN range, protecting a three-phase circuit against both overload and short circuit and tripping automatically when either occurs. Its three linked poles switch and protect all three phases as one, the choice for three-phase main-switch and heavy sub-main duty in homes and light commercial boards – large motors, plant and high-demand feeds – with a 6kA breaking capacity for the fault levels found in those switchboards.

C curve for motor and mixed loads.
The C tripping characteristic trips on short circuit at 5 to 10 times rated current, the general-purpose curve suited to mixed resistive and inductive loads including the inrush of three-phase motors. Backed by a 6kA short-circuit breaking capacity to IEC 60898-1 and energy limiting class 3, the MSN363 limits let-through energy during a fault to help protect downstream cabling.

Built for Australian switchboards.
At three modules (52.5mm) wide, 83mm high and 70mm deep, the MSN363 clips onto standard 35mm DIN rail with 360° mounting flexibility, and its terminals take rigid conductors up to 35mm² at 2.8Nm. It is compliant with AS/NZS 60898.1, rated IP20, and operates from -25°C to 70°C to suit distribution boards and homes across Australian conditions. With 18.3W dissipation per pole at full load, allow for heat in tightly packed boards. Hager auxiliaries including the MZ201 auxiliary contact, MZ202 alarm contact and MZ203/MZ204 shunt trips are available.

Q: Is the Hager MSN363 a three-phase breaker?
Yes. It is a 3-pole (3P) MCB that switches and protects all three phases of a 415V circuit together; it does not include a separate neutral pole.

Q: What does the C curve mean on the MSN363?
The C curve trips on short circuit at 5 to 10 times the rated current, making it the general-purpose characteristic for mixed resistive and inductive loads including motors.

Q: What is the difference between the MSN363 (6kA) and a 10kA MCB?
6kA is the rated short-circuit breaking capacity, suited to residential and light commercial boards; a 10kA breaker such as Hager's NT range is specified where fault levels are higher, typically in commercial and industrial installations.
