The low-voltage control part has advanced motor protection and flexible soft start setting function.

The high voltage part communicates with the low voltage control part through optical fibers, and the high and low voltage parts are safely isolated without interference from the high voltage part. The low-voltage control power supply adopts the 220/120VAC standard, which has a wider range of applications.

Built in 120V synchronous transformer, accurately collects power waveform signals.

The isolation switch at the incoming end is mechanically interlocked with the cabinet door to ensure that the cabinet door cannot be opened when the isolation switch is closed and the isolation switch cannot be closed when the cabinet door is open.

The visible grounding busbar ensures the safety of operation.

The selection of fuses is based on the starting characteristics of the soft starter, with a fuse indication.

Net side vacuum contactor (meeting the requirements for straight up).

Bypass vacuum contactor (meeting the requirements for straight up).

The heavy-duty SCR design adopts a separate synchronous pulse transformer isolation to ensure reliable triggering of the thyristor.

RTD control part (optional), monitors the RTD thermistor inside the motor to monitor the motor temperature. Can input up to 12 RTD signals.

Zero sequence current protection (optional).

The HRV series soft starter can not only provide conventional starting control curves, but also set starting and stopping curves that fully meet the load starting requirements according to actual situations, thereby achieving smooth starting and stopping of the motor and eliminating mechanical impacts on related equipment.

The HRV series soft starter provides the best starting and protection curve for the motor by detecting the thermal capacity of the motor. The complete protection function can completely replace the comprehensive protector of the motor, meeting the increasingly demanding requirements of users for motor protection.

The high voltage and low voltage control parts of the HRV series soft starter transmit signals through optical fibers, which is safer for users and can avoid interference from the main circuit to the control circuit, ensuring the normal operation of the equipment.
