D2S-10LD

D2S-10LD Application Field and Working Principle

The D2S-10LD series is a special type of D2S limit switch. It is mainly used in power transmission and distribution for overload, overcurrent, under voltage, overload tripping and other applications. It is typically used as a remote indication switch on distribution systems.

The D2S-10LD series consists of a single-pole, double-throw switch. It’s designed to be capable of supporting high current loads. The device is designed to operate in environments with high temperatures, dust and vibration.

The operation of the switch relies on a spring-type load-sensing mechanism. When a current or voltage above a given threshold is detected, the spring force drives a plunger or actuator. The actuator then pushes or pulls the switch aside, moving it from one position to the other. Indicating the user that the circuit has been triggered.

The loading capacity of the switch varies with the type of spring and the operating temperature. The operating temperature range is between -20 and 80 degrees Celsius. The switch can also be used in environments with extreme temperatures, up to 200 degrees Celsius. The load capacity of the switch also varies depending on the type of load applied.

The D2S-10LD series is also designed to protect against mechanical overloads by automatically disconnecting the load when the load exceeds a predetermined set point.

The switch is designed to experience minimal wear, thus ensuring a long service life. The enclosure of the switch is flame-retardant and is weather-proof, making it suitable for use in a wide range of indoor and outdoor applications.

The D2S-10LD series is a low-cost, reliable and efficient switch for various applications, including electricity transmission and distribution, remote indication, electrical protection and overload tripping.
