Providing precise, low-noise thermal regulation in demanding industrial environments, the Omron G3PE-245B-3N acts as a heavy-duty three-phase solid-state contactor engineered for high-frequency heater switching. Designed with a built-in heat sink and integrating advanced phototriac isolation, this device ensures safe galvanic separation between the control logic and high-power load circuits. The integrated zero-cross function suppresses electromagnetic interference by synchronizing load activation with the AC voltage zero points, making it highly compatible with noise-sensitive automation environments.
| Manufacturer | Omron |
| Model Number | G3PE-245B-3N |
| Device Type | 3-Phase Solid State Relay (Heater Control) |
| Number of Elements | 3-phase, 3-element |
| Rated Control Voltage | 12 to 24 VDC |
| Operating Voltage Range | 9.6 to 30 VDC |
| Input Current | 10 mA max. (at 24 VDC) |
| Must Operate Voltage | 9.6 VDC max. |
| Must Release Voltage | 1 VDC min. |
| Rated Load Voltage | 100 to 240 VAC (50/60 Hz) |
| Load Voltage Range | 75 to 264 VAC (50/60 Hz) |
| Load Current | 45 A (at 40 degC) |
| Minimum Load Current | 0.5 A |
| Inrush Current Resistivity | 440 A (60 Hz, 1 cycle) |
| Permissible I2t | 1260 A2s |
| Applicable Load Capacity | 15.5 kW (at 200 VAC) |
| Isolation Method | Phototriac |
| Zero Cross Function | Equipped |
| Terminal Structure | Screw terminal |
| Shipping Weight (Calculated) | 3.0 kg |
| Terminal Designation | Terminal Class | Description / Function |
|---|---|---|
| A1 (+) / A2 (-) | Input Terminal | DC Control Voltage Input (12 to 24 VDC trigger signal) |
| L1 / L2 / L3 | Load Line Input | 3-Phase AC power line input connections (100 to 240 VAC) |
| T1 / T2 / T3 | Load Output | 3-Phase AC power connection directly to the heating elements |
The "3N" suffix denotes a 3-phase, 3-element controller which switches all three distinct phases. If replacing older 2-element models (such as the G3PE-245B-3, which only switches two phases while passing the third directly), verify panel wiring diagrams. The 3-element version provides superior isolation and meets stricter safety codes requiring all phase lines to be interrupted during off-cycles.
Solid state relays generate approximately 1.5 Watts of heat per Ampere of load current. When installing this 45 A unit in fully enclosed control panels, calculate total thermal load and ensure adequate air circulation or force-cooling. Ambient temperature inside the panel must not exceed 40 degC to maintain the full 45 A rating without derating the device.
To prevent localized overheating and terminal failure under high current loads, use crimp-style closed-loop ring terminals for the main load lines (L1/L2/L3 and T1/T2/T3). Ensure all load terminals are tightened to a torque rating between 1.47 and 2.45 N-m. Periodically inspect connection torque during routine plant maintenance cycles.
