G3PB Solid State Relays (SSR) – Precision Power Switching for Industrial Heating and Automation
Solid State Relays (SSRs) from the G3PB series are semiconductor-based switching devices designed for high-frequency, zero-cross, or phase-angle control of resistive and inductive loads. Unlike electromechanical relays, G3PB units offer silent operation, no contact wear, and superior longevity, with typical rated currents ranging from 5A to 90A per phase and operating voltages up to 480V AC. These relays feature built-in heat sinks, LED status indicators, and optional overcurrent protection. They are available in single-phase (1P) and three-phase (3P) configurations, with control inputs compatible with 4-20mA, 0-10V DC, or standard 24V DC logic signals. The G3PB series is globally recognized as a solid-state contactor or static relay, ensuring precise thermal management in industrial processes.
G3PB SSRs are primarily deployed in industrial heating applications, including plastic injection molding machines, packaging sealers, drying ovens, and HVAC systems. They are also used in lighting control, motor soft-start circuits, and chemical process heaters. Their robust design makes them suitable for installation in control panels, distribution boards, and automated production lines where rapid cycling and high reliability are critical. The series supports DIN rail and panel mounting, with IP20 protection for indoor environments.
The G3PB category includes several subcategories: G3PB-2A (single-phase, 5-25A), G3PB-4B (three-phase, 25-90A), and G3PB-5C (high-current, 60-90A). Key article codes follow the pattern G3PB-XXXX-XX, where the first digits indicate current rating and the last digits denote control voltage (e.g., G3PB-2020-24 for 20A, 24V DC control). Other variants include G3PB-1000-48 (10A, 48V DC) and G3PB-5000-240 (50A, 240V AC control). These codes are standardized for easy identification across global catalogs.
