IC Electronic P-Line SC 1 DD 40 30 semiconductor contactor, 24-480VAC, 30A, contol voltage 5-24VDC *new*

SC 1 DD 40 30 is an industrial solid-state contactor designed for controlling three-phase AC loads and motors. Instead of mechanical contacts, the device uses solid-state technology (ie semiconductor technology), which provides silent operation, high switching speed, and a significantly longer service life in demanding environments.

Applications:

• Controlling motors (pumps, fans, compressors, process equipment).
• Resistive and inductive loads.
• Automation panels and control systems.
• Applications requiring maintenance-free operation and high reliability.

Features:

• Wide operating voltage range 24–480VAC, 50/60Hz.
• No mechanical contacts. This eliminates arcing and mechanical wear.
• Silent and fast switching.

Benefits:

• Excellent choice for high-frequency switching applications.
• Minimal maintenance requirements.
• Enhanced durability against vibration and harsh environmental conditions.
• Higher reliability compared to traditional mechanical contactors.

Industrial applications:

• Machine building.
• Automation and process control.
• Heating, ventilation, and air-conditioning systems (HVAC).
• Pump stations and conveyor systems.
