Lutron · PLCs & Industrial Controllers

Description  The Lutron GP24-1204ML-20 is a 24-circuit dimming panel designed for centralized commercial lighting control applications. Operating at 120 V on a 3-phase, 4-wire system, it provides controlled dimming and switching for multiple lighting zones. This unit is part of the Grafik Systems platform and is configured with main lugs only for direct distribution integration.     Technical Specifications  Condition New/Never Used Surplus Brand Lutron Category Lighting Subcategory Lighting Controller Part Number GP24-1204ML-20 Series GRAFIK Systems – GP Dimming Panel Number of Load Circuits 24 Branch Circuit Rating 20 A Input Voltage 120 V Phase 3-Phase Wiring 4-Wire Panel Feed Type Main Lugs Only (ML) Enclosure Rating NEMA Type 1, IP20 Construction 16 Gauge Steel Cooling Method Convection (No Fans) Surge Protection ANSI/IEEE 62.41-1980 Memory Retention 10-Year Power Failure Memory Weight 175 lb Information About GP24-1204ML-20 The GP24-1204ML-20 is part of the Lutron GRAFIK Systems GP Dimming Panel family, engineered for centralized lighting control in commercial and institutional environments. It provides dimming and switching control across 24 individual load circuits. The enclosure is rated NEMA Type 1 (IP20) for indoor installation and constructed from 16-gauge steel. The panel utilizes passive convection cooling through a patented ribbed aluminum heat sink base, eliminating the need for internal cooling fans. A built-in 10-year power-failure memory automatically restores lighting to the last selected scene after a power outage. Key Features:    24 Dimming Circuits: Provides independent control of twenty-four lighting loads. 120 V Operation: Designed for standard 120-volt commercial electrical systems. 3-Phase, 4-Wire Configuration: Compatible with multi-phase power distribution. Main Lugs Only (ML): Supports direct feed connection without a main breaker. 20 A Branch Circuit Breakers: Integrated branch protection for each circuit. Convection Cooling System: Fan-free thermal management using ribbed aluminum heat sink design. 10-Year Scene Memory: Automatically restores previous lighting settings after power loss. Surge Protection Compliance: Meets ANSI/IEEE 62.41-1980 standards for surge resistance up to 6000 V and 3000 A. The GP24-1204ML-20 delivers the reliability and precision required for large-scale commercial lighting control systems.
