Installation bracket thread specifications: M14, M16
◆ Lock bolt stroke: 14mm
Installation method: DSN-Z left side installation


The DSN-II/Z series indoor electromagnetic lock is an electronic control interlocking device that prevents electrical misoperation of high-voltage switchgear. It is mainly suitable for interlocking the front and rear cabinet doors, isolating switches, circuit breakers, grounding wires and other parts that need to be locked in indoor high-voltage switchgear to prevent misoperation. It is an indispensable locking device for power generation and supply departments. In addition, to meet the needs of integrated automation substations, this series of electromagnetic locks also adds auxiliary contacts inside the lock. It can provide users with a pair of corresponding switch contacts at the opening and closing positions of the lock, facilitating mutual interlocking and comprehensive automated sampling of the lock, avoiding empty spaces, and is an ideal locking device for modern substation equipment. The "electric control lock" product of Zhuanli solves the defect of mechanical program lock keys in comprehensive automation substations that cannot be controlled and managed.

3、 Purpose and scope of use
This product is an electrical interlocking device for preventing electrical misoperation of high-voltage switchgear. It is mainly used to achieve forced interlocking of high-voltage switchgear doors and other places that require safety interlocking, preventing accidental entry into live compartments and misoperation. It is an indispensable locking device for power generation and supply departments.

The altitude shall not exceed 2000 meters.
The ambient air temperature shall not exceed+40 ℃, not be lower than -5 ℃, and the average temperature within 24 hours shall not exceed+35 ℃.
The installation location has clean air, and the relative humidity of the atmosphere should not exceed 50% when the ambient temperature is 40 ℃. The average relative humidity in humid months is 90% when the average temperature is 25 ℃, taking into account the condensation that occurs on the surface of the product due to temperature changes.
