SSR-400DA Solid State Relay

This ready-to-use three-phase solid state relay (SSR) assembly combines three high-performance SSR modules with a heavy-duty aluminum heatsink and cooling fan, delivering reliable, contactless power switching for three-phase industrial systems.

Key Features:

Complete 3-Phase Solution: Pre-assembled with three SSR modules, eliminating the need for separate component sourcing and installation.
Efficient Cooling System: Large aluminum heatsink paired with a high-speed cooling fan ensures optimal heat dissipation, even under continuous high-load operation.
High-Current Capacity: Designed for heavy-duty three-phase loads, ideal for heating, motor control, and power distribution applications.
Contactless Switching: No moving parts or mechanical contacts, eliminating arcing, noise, and wear for long service life.
Easy Installation: Pre-wired and ready for direct integration into three-phase control circuits, reducing setup time and complexity.
Industrial-Grade Reliability: Built to withstand the demands of continuous-duty industrial environments, with stable performance and minimal maintenance.

Applications:

Three-phase industrial heating systems
Motor control and soft-start applications
Power distribution and process automation
HVAC and industrial equipment control
