Comprehensive Motor Protection Solution: NDR2-38 Series Thermal Overload Relays from Liangxin (Shanghai Nader)
Ensuring operational safety and longevity of electric motors requires robust protection against thermal overload—a critical function efficiently provided by the NDR2-38 Series Thermal Overload Relays. Designed under the Shanghai Liangxin (Nader) brand, this relay series serves as an integral safeguard in motor control circuits, particularly compatible with NA2-38 mounting bases.
Key Features & Specifications:
-
Protection Mechanism: The NDR2-38 range utilizes a precision-engineered bimetallic thermal tripping system that responds to current-induced temperature rise. When motors operate beyond their rated current capacity—due to overload, phase failure, or phase unbalance—the relay trips to disconnect power, preventing potential motor damage and fire hazards.
-
Model Versatility: With a comprehensive model lineup (NDR2-3801~NDR2-3822), the product accommodates a broad spectrum of applications. Whether your needs fit the NDR2-3805, NDR2-3812, or NDR2-3821 configuration, the series offers adjustable trip settings, reset modes (manual or automatic), and current calibration to match motor specifications.
-
Industrial Durability: The relays are constructed for demanding environments, featuring dust-resistant enclosures, terminal placement for optimal heat dissipation, and robust contact systems. Enhanced for gravitation insensitivity, they maintain performance accuracy regardless of orientation.
Application Excellence:
NDR2-38 Thermal Overload Relays are extensively adopted in industrial settings—from machine tools and compressors to pumps and conveyor systems—as a fail-safe component complementing contactors (e.g., within molded case starter assemblies). Their reliability translates into lower maintenance costs and downtime by proactively detecting abnormal loads before irreversible motor degradation occurs.
Why Choose NDR2-38 Relays?
- Engineered Precision: Calibrated thermal calibration curves ensure timing accuracy across varying overloads.
- Dependability: Shanghai Liangxin production adheres to IEC 60947-4-1 safety standards.
- Compatibility: Seamless integration with NA2-38 contactor bases simplifies installation in existing setups.
For motor-centric operations prioritizing uptime longevity, the NDR2-38 Thermal Overload Relay Series delivers protection assurance—an essential investment for industrial energy control systems.
