Weil McLain 383-500-604 Fuses mechanical joints in refrigerant linesThe Weil McLain 383 500 604 is a critical 12A slow blow fuse designed specifically for the protection of advanced control modules in condensing gas boilers. For service technicians troubleshooting a blank display or a non responsive Ultra U Control module, these high amperage glass fuses are the standard requirement to safeguard line voltage circuits against transient surges without premature tripping. Unlike standard fast acting alternatives, the
