Features

• Voltage detection type three-phase motor reverse rotation prevention relay
• Relay to prevent reverse rotation of motor due to wrong wiring.
• At the same time as the power supply is turned on, the positive phase and the negative phase are discriminated, and the turning on of the magnet contactor is prevented in the negative phase state.
• By the wiring method, the magnet contactor is prevented from being fed out of phase.
• Small plug-in type, no adjustment required.
• Because of the voltage detection system, it can be used regardless of the load current.
