Specter single-phase miniature switch 25 amps type C :
About the miniature switch, it can be said that the fuse is a protective device that is used in electrical equipment and circuits when the current exceeds the permissible limit. It cuts the circuit so that other equipment is not damaged.
Miniature switches use two mechanisms for their operation.
Bitmal function for overload protection
Magnetic function for connection protection Short
In terms of the number of bridges, the miniature switches are divided into 2 single-phase and three-phase parts, and in terms of the cut-off time, they are divided into two fast-acting and slow-acting states. They are also divided into types K, D, C, B and Z in terms of use. B type miniature switch: This type of miniature switch is mostly used in homes and the overload current is between 3 and 5 times the rated current. This type of switch is considered to be fast-acting type.
Type C miniature switch: This type of switch is mostly used in industry and it cuts the overload current between 5 and 10 times the rated current in a specified time. The switch is considered a slow-acting type. D type miniature switch: This type of switch is used mostly in special industrial applications such as transformers and cuts off the overload current 10 to 20 times the rated current. K type miniature switch: This type of key is used in transformer and engine. Its function is between type C and D. Z type miniature switch: This miniature will issue a shutdown command at a specific time when the passing current exceeds the rated current. This key is used in very sensitive circuits.
Note: In the case of miniature keys, peripherals can be installed to detect the on/off status or alarms. :
