High Voltage Solid State Relay LSR3-3-3150DA SSR 3-Phase 150A 1200VAC Industrial Panel Mount Explosion Proof Custom R&D
High Voltage 3-Phase SSR 150A 1200VAC — R&D Powered, Cost Optimized
Semi-Permanent Life · Explosion Proof · Compact · We Design Your Complete Switching Solution
???? We Don't Just Sell SSRs — We Engineer Power Control Systems
This 3-phase 150A 1200VAC SSR is a high-voltage workhorse for industrial heating, motor control, and power distribution. But the real value is our R&D engineering partnership. Need 200A instead of 150A? Different control input? Custom thermal management for a confined cabinet? Explosion-proof certification for hazardous environments? Our engineering team redesigns the SSR to your exact requirements — and we optimize the design to reduce your system-level cost while maintaining or improving performance.
