Reliable Single-Phase SSR for Continuous Machine Duty
The G3NB-210B-1 is engineered for frequent AC switching in automation cabinets where durability and stable behavior matter. It is commonly selected for thermal load control and repetitive process switching.
Durable High-Cycle Operation
With no mechanical contacts, the relay avoids contact erosion and bounce, supporting high switching frequency use cases.
Clean Switching Profile
Zero-cross triggering is well suited to resistive loads and helps reduce noise compared with random turn-on methods.
Straightforward Integration
The module format supports common panel mounting practices and works with standard control-stage outputs.
Typical Applications
- Handles repetitive AC load switching
- Improves process repeatability in heat control
- Supports quieter cabinets
- Reduces downtime from relay wear
- Enables compact SSR replacement strategy
- Works in legacy or new control panels
Buying Checklist
- 10A class for standard branch loads
- Zero-cross for reduced EMI events
- Solid-state durability for high cycles
- Easy PLC/control integration

Frequently Asked Questions
What's the advantage of G3NB series?
Compact size, cost-effective, reliable zero-cross switching. Ideal for space-constrained panels, cost-sensitive applications, general AC load switching.
Do I need heat sink?
For loads under 5A at normal ambient, no heat sink needed. For 5-10A loads or high ambient, use heat sink. SSR power dissipation: 1.6V × load current.
Can this switch DC loads?
No, G3NB is AC output only. For DC loads, use G3NA-D series DC output SSRs or G3NE MOS FET SSRs.
What's the maximum load?
10A at AC200-240V resistive load. For inductive loads (contactors, solenoids), derate to 60-70% or add varistor protection.
