Why it Matters

The highest-current MSN breaker.
The MSN163 is a 63A miniature circuit breaker, the top of Hager's 1-pole MSN range, protecting a circuit against both overload and short circuit and tripping automatically when either occurs. A 63A rating is the choice for main-switch and heavy sub-main duty in homes and light commercial boards – sub-boards, large appliances and high-demand feeds – and its 6kA breaking capacity suits the fault levels found in those switchboards.

C curve for high-inrush 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 moderately inductive loads and high-inrush circuits. Backed by a 6kA short-circuit breaking capacity to IEC 60898-1 and energy limiting class 3, the MSN163 limits let-through energy during a fault to help protect downstream cabling.

Built for Australian switchboards.
At one module (17.5mm) wide, 83mm high and 70mm deep, the MSN163 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 meter boxes, distribution boards and homes across Australian conditions. With 7.4W dissipation 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: What is the Hager MSN163 used for?
It is a 63A single-pole MCB, the highest rating in the 1-pole MSN range, for protecting main-switch and heavy sub-main circuits against overload and short circuit in residential and light commercial boards.

Q: What does the C curve mean on the MSN163?
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 moderately inductive loads.

Q: What is the difference between the MSN163 (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.
