Magentic release
An electromagnet with plunger ensure instantaneous tripping in case of short circuit. The IEC60898 distinguishes three different types, following the current for instaneous release: type B,C,D
| Test Current |
Tripping Time | Applications | |
| B | 3In 5In | t≥0.1s NonTripping t<0.1s Tripping | Only for resistive loads such as: -electrical heating -water heater -stoves |
| C | 5In 10In | t≥0.1 NonTripping t<0.1s Tripping | Usual loads such as: -lighting -socket outlets -small motors |
| D | 10In 20In | t≥0.1s NonTripping t<0.1s Tripping | Control and protection of circuits having important transient inrush currents(large motors) |
Thermal release
The release is initiated by a bimetal strip in case of overload
The standard defines the range of release for specific overload values
Reference ambient temperature is 30°C
