Modular contactor for rail, 4xNO contacts, 63A, 24V DC ST63-40-24ACDC

Modular contactor for DIN rail mounting – reliable circuit switching

This modular contactor, designed for mounting on a 35 mm rail, is a robust solution for controlling electrical circuits. Designed for reliability and ease of installation, it will work well in both domestic and industrial applications. It features a four normally open (4NO) contact configuration, providing flexibility in connecting various loads.

Construction and operating parameters

The contactor is characterized by a rated current of 63A and a coil voltage of 24V AC/DC, making it versatile in application. Its modular design (3 modules) allows for easy integration with existing installations. Made of high-quality materials, it ensures durability and resistance to environmental conditions. The IP20 protection class guarantees safe use in standard conditions.

Application and benefits

• Versatility: Ideal for controlling lighting, heating, electric motors and other devices requiring frequent switching on and off.
• Safety: Compliance with IEC 61095 standard ensures a high level of safety.
• Durability: Thanks to the high electrical (1x10⁵ cycles) and mechanical (1x10⁶ cycles) switching durability, the contactor will serve for a long time without failure.
• Easy installation: Modular design facilitates quick and easy mounting on a standard 35 mm rail.
• Efficiency: The rated switching power AC1 (230V) is 24 kW, and AC3 (230V) – 8.5 kW, allowing it to handle even demanding loads.
• Practical solutions: Screw terminals with a capacity of 16 mm² provide a secure connection of wires. The coil power consumption is only 6.4 W.

Additional information: the insulation voltage is 4 kV and the operating temperature is in the range of -25°C to +50°C. The contactor is adapted to work in AC and DC circuits.
