Aluminum Heat Sink for Solid State Relay (SSR) — Three 3Phase A purposebuilt aluminum heat sink designed to improve heat dissipation for solid state relays used in threephase systems. This passive cooling accessory helps maintain lower operating temperatures for SSRs, improving reliability and reducing the risk of thermal shutdown under continuous load. Key benefits Effective thermal management: Transfers heat away from SSRs to reduce junction temperature and help maintain stable operation. Threephase support: Sized and arranged to accommodate three SSR channels in a single, consolidated heat sink for cleaner panel layout and simpler installation. Durable, lightweight construction: Machined from aluminum for good thermal conductivity, low weight, and corrosion resistance. Improved reliability and longevity: Better cooling minimizes thermal stress on SSR components, extending service life and reducing maintenance interventions. Simple integration: Designed to be mounted in control cabinets or on equipment frames alongside SSR modules for straightforward system upgrades. Key attributes Functionality: Passive heat dissipation for solid state relays used in threephase power control. Compatibility: Intended for standard threephase SSR modules and installations; suitable where multiple SSRs are mounted together to manage load across three phases. Material: Aluminum construction for efficient thermal transfer and durability. Performance: Provides a stable thermal path away from SSRs to help prevent overheating during continuous or load operation. Form factor: Configured to support three SSR channels in a single heat sink to streamline installation and wiring in threephase systems. Typical applications Industrial automation and motor control panels where threephase SSRs control motors, heaters, or pumps and require reliable thermal management. HVAC and process heating systems using SSRs to switch heating elements across three phases, helping maintain consistent operation under continuous duty. Power distribution, batching, and manufacturing equipment that uses threephase SSRs for load switching and benefits from consolidated heat dissipation. Installation and maintenance Intended for direct mounting with standard SSRs in control cabinets or on mounting rails; follow SSR manufacturer mounting recommendations for torque and thermal interface materials. Keep fins and surfaces of dust and debris to preserve thermal performance. Aluminum construction allows easy cleaning with a dry brush or compressed air. Use this aluminum heat sink to centralize cooling for threephase SSR installations, reduce thermal stress, and simplify cabinet layout without adding active cooling components.
