Product Overview

The HC25 Series Three-Phase High Current Thermal Protector is engineered for heavy-duty applications requiring reliable over-temperature and over-current protection. Designed with a pure temperature-sensitive mechanism, this protector minimizes current interference and ensures ultra-low internal resistance (≤50mΩ) for energy-efficient operation in high-power systems.

It features epoxy-sealed construction to withstand harsh environments such as oil pumps, industrial motors (up to 35A), transformers, and electric vehicle charging systems. The precision-calibrated temperature range (70°C-160°C ±5°C) and vacuum varnished contacts guarantee stable performance in continuous duty cycles, making it the ideal safeguard against motor burnout in HVAC systems, agricultural equipment, and automated machinery.

Key Features
  • High-Current Capacity: Supports 25A/35A three-phase loads with minimal voltage drop, perfect for 250V AC industrial motors and pumps.
  • Precision Thermal Protection: Pure bimetal technology with ±5°C accuracy prevents false tripping while protecting windings from overheating damage.
  • Industrial-Grade Durability: Epoxy-encapsulated design resists oil contamination, dust ingress, and vibration in oil extraction pumps and construction equipment.
