Product Overview

The ZHR10 Series Integrated Bypass Soft Starter (Built-in Bypass Intelligent Motor Soft Starter) is an advanced digital soft start solution, suitable for 0.37~400KW three-phase AC asynchronous motors. As a core Bypass Soft Starter, its standout feature is automatic switching to bypass operation after start-up completion, reducing energy consumption and improving equipment stability.

This intelligent motor soft starter supports two start modes (voltage ramp start, current-limiting start) and two stop modes (free stop, timed soft stop). As a professional in-line soft starter, it is equipped with a complete protection system, including multiple safeguards such as input phase loss, output phase loss, overload, overcurrent, and underload. It supports RS485 communication (Modbus-RTU protocol) and Chinese/English display, adapting to 220V/380V voltage levels and star or internal delta connection methods to meet diverse industrial scenario requirements for soft starter applications.

Its core design focuses on high reliability, low energy consumption, and easy operation. Through optimized circuit layout and built-in bypass structure, this Bypass Soft Starter ensures long-term stable operation in harsh industrial environments, suitable for various small to medium-sized industrial equipment such as pumps, fans, and conveyors that require a reliable motor soft starter.

Product Features

Built-in Bypass Design for Energy Efficiency (Integrated Bypass Soft Starter)

As a professional Integrated Bypass Soft Starter, it automatically switches to bypass operation after start-up, reducing thyristor loss, lowering energy consumption, and extending the service life of this motor soft starter.

Dual Start Modes for Diverse Loads (Motor Soft Starter)

This soft starter supports voltage ramp start (smooth start to reduce impact) and current-limiting start (controls start-up current to protect the power grid), which can be flexibly selected according to load characteristics of equipment using in-line soft starter.

Comprehensive Protection System for Safety & Reliability (Bypass Soft Starter)

This Bypass Soft Starter integrates multiple protections including input phase loss, output phase loss, running overload, start-up overcurrent, running overcurrent, underload, thyristor breakdown, and three-phase imbalance to fully protect motors and equipment using motor soft starter.

Intelligent Communication & Remote Control (Soft Starter)

Equipped with an RS485 communication interface and supporting Modbus-RTU protocol, this motor soft starter enables remote control, centralized management, and data monitoring, reducing on-site operation difficulty for Integrated Bypass Soft Starter users.

Multi-Language Display for Easy Operation (Motor Soft Starter)

This soft starter supports Chinese/English bilingual operation interfaces, with clear LED status indicators and a detachable operation panel. Parameter setting is intuitive and fault troubleshooting is convenient for in-line soft starter applications.

Pump-Specific Functions for Scenario Optimization (Soft Starter)

This motor soft starter supports 4 pump-matching functions (float switch, electric contact pressure gauge, liquid level relay, etc.), optimizing start-stop logic for water supply/drainage scenarios and adapting to various pump equipment using Bypass Soft Starter.

Flexible Installation for Diverse Spaces (Integrated Bypass Soft Starter)

This Integrated Bypass Soft Starter features a wall-mounted installation design with a compact size, adapting to different on-site installation conditions. The power range covers 0.37~115KW, meeting the driving needs of small to medium-sized equipment requiring a soft starter.
