A DC isolator switch is an electrical contraption fashioned to isolate/disconnect a DC circuit from its power source. The 1000 voltDC isolator switch is specifically used in DC systems operating at voltage levels reaching 1000 volts.

Features
The DC isolator switch functions as a safety device. It allows for safe maintenance, inspection, or repair of electrical equipment by providing a means to de-energize the circuit.
When evaluating a 1000-volt DC isolator switch, some of the features described may include:
- A 1000-volt DC isolator switch’s voltage rating defines and sets its limit at 1000 volts. Beyond this, it interrupts electrical flow in the circuit isolating the equipment from the DC source.
- A 100-volt DC isolator switch can have lockout/tagout provisions only allowing operation by authorized personnel as a safety measure.
- It can feature extinguishing mechanisms such as arc suppression for safe operation and minimized risk of arc flash in case of interruption.
- Materials used in the construction of 1000-volt DC isolator switches are durable and capable of tolerating electrical and environmental stress conditions.
- May feature visible contacts allowing visual verification of the switch position to indicate circuit status in terms of energization.
- These electrical devices feature manual operation designs allowing straightforward control by alternating between ON and OFF positions.
- These isolator switches comply with relevant industry standards for safety and functionality ensuring effective performance.
- These isolator switches have a compact design optimizing space utilization and making integration in electrical systems straightforward.
