Modular contactor ST63-40/24 modular contactor 4NO contacts I=63A coil voltage U=24V AC 3 modules ST63-40-24V

Modular contactor for efficient circuit control

This 3-module electromagnetic contactor, designed for mounting on a standard 35mm rail, is a reliable solution for both professional installers and end-users. It provides effective switching of circuits up to 63A, while offering compact dimensions and easy installation. The design with four normally open contacts (4NO) allows for controlling various loads, and the coil voltage of 24V AC ensures compatibility with commonly used control systems.

Characteristics and application

This contactor finds wide application in electrical installations of residential and commercial buildings, as well as in industrial automation. It is ideal for controlling lighting, electric heaters, pumps, fans and other devices requiring frequent switching. Its modular construction facilitates integration with electrical distribution boards, and its high mechanical and electrical durability guarantees long-lasting and trouble-free operation. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well.

Key features and benefits

• High performance: Rated current of 63A and switching capacity AC1 up to 24kW and AC3 up to 8.5kW allow for handling demanding loads.
• Compact dimensions: A width of only 3 modules minimizes the space occupied in the distribution board.
• Safety: Protection class IP20 provides basic protection against contact and ingress of solid objects. Insulation voltage of 4kV guarantees safe use.
• Durability: Electrical switching durability of 1x10⁵ cycles and mechanical 1x10⁶ cycles ensures long device life.
• Easy installation: Designed for direct mounting on a 35mm rail, which simplifies and speeds up installation.
• Status indication: Red marker in the window informs about the contactor's on state - quick identification of the device's operating status.
• Versatility: Four normally open contacts (4NO) provide great flexibility in configuring control circuits.
• Compliance with standards: Meets the requirements of IEC 61095 standard, which confirms its quality and safety.

This contactor has a rated operating voltage in the range of 230 ... 230 V and a rated control voltage of 24 ... 24 V. Its mounting depth is 65 mm, and the degree of protection is IP20. The maximum switching capacity for incandescent lamps is as high as 24000 W.

This contactor is a solid choice for anyone who needs a reliable solution for controlling electrical circuits - both in home and industrial installations. Its compact size, high performance and easy installation make it an ideal component for any installer or end-user looking for an effective solution.
