Why it Matters

A workhorse lighting and sub-circuit breaker.
The MSN110 is a 10A miniature circuit breaker, protecting a circuit against both overload and short circuit and tripping automatically when either occurs. A 10A rating is one of the most common sizes on final sub-circuits – lighting and small power runs – and its 6kA breaking capacity suits the fault levels found in residential and light commercial switchboards.

C curve for general-purpose 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 such as lighting and power circuits. Backed by a 6kA short-circuit breaking capacity to IEC 60898-1 and energy limiting class 3, the MSN110 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 MSN110 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. Hager auxiliaries including the MZ201 auxiliary contact, MZ202 alarm contact and MZ203/MZ204 shunt trips are available.

Q: What is the Hager MSN110 used for?
It is a 10A single-pole MCB, a common size for protecting lighting and small power sub-circuits against overload and short circuit in residential and light commercial boards.

Q: What does the C curve mean on the MSN110?
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 MSN110 (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.
