The SZD1163/300010 is a threepole On/Off Isolator Load Break Switch designed for safe isolation of electrical circuits. It is rated for 63 Amp at up to 660 V and features a pad lock compatible rotary cam for secure lockout during maintenance or testing. Key benefits Safe isolation of threephase circuits: provides a clear disconnect to prevent unintended energization during servicing. Lockout compatibility: rotary cam supports pad locking to ensure the switch cannot be operated while under maintenance. Simple manual operation: On/Off action offers straightforward control for routine isolation tasks. Threepole design for balanced threephase switching: suitable for common threephase electrical systems up to the specified voltage and current rating. Key attributes Model and type: SZD1163/300010 threepole On/Off Isolator Load Break Switch Electrical rating: 63 Amp, up to 660 V Poles: 3 Operation: On / Off isolation Safety feature: Rotary cam with pad lock capability for lockout Compatibility and performance Designed for use in threephase electrical installations requiring a dedicated isolation device with load break capability. Suitable for applications where a secure disconnect point is needed for maintenance or safety procedures, with the ability to lock the switch in the OFF position. Usage scenarios Isolate a threephase motor in a production line for routine maintenance or work. Provide a safe disconnection point within a control panel or switchgear during wiring changes or testing. Lockout a feeder or circuit in a facility's electrical distribution setup to ensure safe servicing and compliance with safety protocols. Use cases Scenario 1: A maintenance technician needs to service a threephase motor. The SZD1163/300010 is opened to OFF, and the pad lock is applied to prevent accidental reenergization during the procedure. Scenario 2: During panel modification, the switch is used to isolate a feeder in a switchgear assembly, providing a clear, lockable disconnect point. Scenario 3: For routine safety checks, the device offers a reliable isolation option for threephase circuits up to 660 V, supporting safe testing and inspection workflows.
