In many industrial applications, from industrial oven heating control and small motor frequent start-stop cycles to injection molding machine automation, engineers face a common challenge: managing loads in the 30A to 100A power range while maintaining system reliability and efficiency. Traditional electromechanical relays often fall short, producing arcing, sparks, noise, slow response, and short lifespans, causing unplanned downtime and maintenance headaches.
Even standard solid-state relays come with hidden risks. Poor heat dissipation can lead to SSR failure or explosion, weak anti-interference design may cause false triggering, and the lack of built-in protection can result in load damage. In the mid-power range where reliability is crucial, these issues become critical.
So the question arises: how can engineers choose a “worry-free, durable, and efficient” solution for 30-100A industrial applications?
Meet the solution — CDGKZ Three-Phase Solid-State Relays (30A~100A). Designed specifically for the mid-power industrial sector, these relays solve all the common pain points of traditional relays and standard SSRs. With high reliability, efficient heat dissipation, built-in protection, and strong anti-interference capabilities, CDGKZ relays provide engineers with peace of mind, lower maintenance costs, and improved system efficiency.
Whether you’re controlling industrial ovens, motors, or injection molding machines, CDGKZ three-phase solid-state relays are engineered to deliver long-lasting performance, precise switching, and safe operation, making them the ideal choice for any application requiring 30-100A power handling.
Why CDGKZ Is the Superior Choice for Industrial Applications
Choosing a solid-state relay is not just about switching—it’s about ensuring system reliability, efficiency, and long-term cost savings. CDGKZ three-phase solid-state relays address the common pain points of industrial users with a structured approach: Feature → Advantage → Customer Value.
1. Extreme Reliability for Continuous Production
Feature: Uses top-tier chips such as Infineon and Mitsubishi, combined with an optimized gate drive circuit.
Advantage: Lower thermal loss, stronger overload capability (instant surge resistance 2-3x higher than typical), and extremely consistent switching.
Customer Value: Minimizes unexpected downtime, ensures uninterrupted production lines, and reduces maintenance costs.
2. Innovative Heat Dissipation Design — Say Goodbye to Overheating Concerns
Feature: Low thermal resistance design carefully calculated, high-performance thermally conductive insulation materials, and precision-machined contact surfaces with heatsinks.
Advantage: Thermal resistance far below industry standards, allowing rapid heat transfer to heatsinks.
Customer Value: Lower operating temperatures at the same power, longer lifespan, stable operation in higher ambient temperatures, or with smaller heatsinks—saving installation space and reducing cooling costs.
3. Built-In Multi-Layer Protection — Your “Intelligent Guardian”
Feature: Optional or standard built-in RC snubber circuits, over-voltage protection (OVP), and phase-loss protection (three-phase models only).
Advantage: Effectively suppresses voltage spikes, handles grid fluctuations and back EMF from inductive loads (e.g., motors), protecting both the relay and the load.
Customer Value: Significantly improves system resilience in harsh industrial environments, protects expensive downstream equipment like heating elements or motors, and lowers the risk of system failures.
4. Easy Installation and Commissioning — Boosting Work Efficiency
Feature: Clear status indicators, multiple mounting options (DIN rail or screw), and compact design.
Advantage: Operational status is immediately visible, installation is flexible, and electrical cabinet space is saved.
Customer Value: Reduces installation and troubleshooting time, improving engineers’ overall efficiency.
