Information About G3PB-545B-3N-VD
The G3PB-545B-3N-VD is part of the Omron G3PB Series, a line of compact three-phase solid state contactors engineered for precision AC load switching. Utilizing zero-cross technology, it minimizes electrical noise and surge currents during operation, enhancing load and contactor longevity. This model supports control voltages from 9.6–30 VDC and operates over a wide load voltage range from 180–528 VAC, making it suitable for both resistive and some inductive loads. Designed with screw terminals and an integrated heat sink, the G3PB-545B-3N-VD simplifies installation and ensures optimal performance under continuous-duty conditions.
Key Features:
- Three-Phase Switching: Controls all three phases simultaneously for balanced load operation.
- High Load Capacity: Rated at 45 A with load voltages up to 528 VAC for industrial applications.
- Zero-Cross Triggering: Reduces electrical noise and inrush current during load activation.
- Wide Control Voltage Range: Accepts 9.6–30 VDC for flexible system integration.
- Integrated Heat Sink: Ensures efficient heat dissipation under continuous operation.
- Dual Mounting Options: Supports both chassis and DIN rail installation for convenience.
- Fast, Silent Operation: No mechanical contacts, eliminating arcing and contact wear.
- Industrial Durability: Built for long-term use in heating, motor, and process control applications.
The G3PB-545B-3N-VD delivers the reliability and precision required for high-performance AC load switching in industrial automation and temperature control systems.
