Examine our advanced low-voltage circuit protection, surge suppression, and automatic control devices manufactured to strict international quality standards.
For B2B procurement managers and system integrators seeking absolute reliability in motor control, thermal heating, and low-voltage distribution.
Our 2P AC Contactors utilize high-purity copper windings with specialized varnish insulation. Engineered to prevent coil burnout even under continuous duty or voltage fluctuations between 85% to 110% of rated control voltage.
Designed with high-density silver alloy (AgSnO2) tips that resist electrical arcing and prevent contact welding. This achieves over 1 million operations under AC-3 loaded operations, drastically minimizing maintenance overhead.
Engineered to align directly with IEC 60947-4-1, CE, GB14048.4, and RoHS requirements. The flame-retardant housing meets UL94-V0 compliance, making it suitable for demanding industrial and commercial HVAC systems globally.
Located in Liushi, Wenzhou, Zhejiang, the Electrical Capital of China.
Zhejiang Shuorui Electric Co., Ltd. operates at the epicenter of China's electrical manufacturing ecosystem. By utilizing rich regional industrial resources, we have consolidated our entire R&D, manufacturing, quality testing, and logistics chain to offer maximum efficiency. Our core business philosophy centers on providing "the most cutting-edge technology, the best quality, the most sincere service, and the most favorable price."
To retain our competitive lead in the global market, Shuorui Electric channels a significant percentage of annual revenue back into technological research and development. Our dedicated engineering team continuously optimizes key product categories—including miniature circuit breakers (MCBs), surge protective devices (SPDs), overvoltage and undervoltage protectors, automatic switches, and AC contactors.

Liushi, Wenzhou provides unique industrial clustering advantages that yield faster turnaround times, lower raw material margins, and highly specialized components.
Proximity to leading copper smelters, silver alloy developers, and precision tooling facilities reduces upstream transport costs and secures highly consistent raw material batches.
We configure custom coil voltages (12VDC, 24VAC, 110VAC, 240VAC), auxiliary contact arrangements, and bespoke private-label packaging with exceptionally low minimum order requirements.
Shuorui Electric utilizes semi-automated assembly lines, automated winding machines, and computerized testing benches. This guarantees high precision and output capacity for volume wholesale orders.
Every product is engineered with a modern aesthetic, high functional efficiency, and structural reliability.
In-House QC Inspection Station
During the manufacturing cycle, Shuorui Electric strictly regulates each phase—from raw materials receipt to automated optical inspections (AOI) and final testing of assembly lines. We have implemented rigorous verification procedures, utilizing modern calibration machines to check operation tolerances, thermal stability, and circuit interruption reliability.
We strive to make every batch consistent, ensuring our international buyers can deploy our devices in their regional markets with complete operational confidence.
Wide spectrum of low-voltage electrical controls to suit global grid specifications.
Custom color housings, tailored printing parameters, and specialized packaging structures.
Accredited ISO9001 facilities adhering to globally verified industrial compliance protocols.
Our 2-pole AC contactors are widely deployed in commercial, industrial, and residential environments.
Designed to control single-phase compressor motors and fan blowers. The 2-pole configuration switches both active and neutral lines simultaneously, providing electrical isolation and protection during cycles.
Integrated downstream of solar micro-inverters or main inverter stages to control low-voltage AC outputs. Works alongside SPDs to provide circuit disconnection under faults or schedule-based maintenance.
Ideal for AC-1 and AC-3 resistive/inductive heating elements, industrial process pumps, water filtration loops, and ventilation fans. Ensures long-life operation under continuous switching duty.
Watch our actual assembly lines, advanced CNC machines, and testing stations in Liushi.
We hold numerous utility patents, system design standards, and conformity certificates to fulfill localized regulatory requirements across multiple jurisdictions.
Providing enterprise buyers with reliable logistics, certification paths, and engineering support for international electrical distributions.
We work with distribution partners in North America, Western Europe, and Southeast Asia to offer technical consultation, onsite diagnostics, and rapid warranty replacement parts.
All component parts align with REACH, WEEE, and RoHS. We verify our supply chain to ensure complete exclusion of prohibited substances, facilitating export and customs clearance.
We support various B2B payment terms (L/C, T/T) and provide customs classification, container consolidation, and ocean/air freight booking out of Ningbo and Shanghai ports.
