1. The relay is mainly used in three-phase squirrel cage motor reverse connect brake circuit, available in asynchronous motor energy consumption braking circuit for motor plant after, automatically cut off the DC power supply
Relay 2. In the continuous, reliable work below 3000 rpm, in repeated short-term work system (frequent starting and braking) per minute should be not more than 30 times.
3. The relay for 150 rpm, which can move.100 RPM following contact back to the normal position.
4 the contact current is less than or equal to 2A, the voltage is less than or equal to 500V.
5 the contact life, under no more than the rated load, not less than 100000 times.
