Product Description
The HCET HC25 Three-Phase High Current Thermal Protector is a precision-engineered safety solution designed for heavy-duty industrial applications. With a rated capacity of 16A, 25A, or 35A at 250V AC 50/60Hz, this epoxy-sealed protector ensures ultra-low internal resistance and minimal current interference, making it ideal for pumps, transformers, high-power motors, and battery charging systems.
Featuring a preset temperature calibration range of 70°C to 160°C (±5°C/±8°C accuracy), its closed structure provides dust-proof and impact-resistant protection in harsh environments. The pure temperature-triggered mechanism eliminates false tripping caused by current fluctuations, while the insulated casing design meets international electrical safety standards.
Product Features
- Industrial-Grade Durability - Epoxy resin encapsulation with vacuum varnish ensures moisture resistance and mechanical stability for long-term operation in pumps, compressors, and motor-driven equipment.
- Precision Temperature Control - Pure thermal activation design (no magnetic interference) with factory-preset thresholds (70-160°C) guarantees accurate overload protection for transformers and power systems.
- High Current Capacity - Supports 3-phase systems up to 35A/250V AC, specifically engineered for HVAC systems, industrial machinery, and EV battery charging stations.
- Zero-Maintenance Design - Sealed construction prevents dust/contaminant ingress, eliminating field adjustments and reducing downtime in manufacturing plants.
