Modular contactor ST63-31 modular contactor 3NO+1NC contacts I=63A coil voltage U=230V AC 3 modules

Modular contactor for mounting on a 35mm rail

This modular contactor, designed for direct mounting on a standard 35mm rail, is a reliable solution for controlling electrical circuits. It features a compact design – occupying only 3 modules – which allows for efficient use of space in distribution boards. This is particularly important when designing installations in limited spaces.

Design and application

This contactor has a contact configuration of 3NO (normally open) + 1NC (normally closed), providing great flexibility in control applications. The rated operating current is 63A, and the maximum switching capacity for incandescent lamps is as high as 24000W, making it suitable for high-power loads. It is designed to operate at 230V AC in both the control and power circuits. This makes it suitable for a variety of applications, from lighting control to switching motors and other electrical devices.

Advantages and benefits

• Compact dimensions: A width of only 3 modules makes it easy to install even in crowded distribution boards.

• High switching capacity: Rated current of 63A and switching capacity of 24000W allow for handling demanding loads.

• Versatility: 3NO+1NC contact configuration provides flexibility in various control applications.

• Safety: IP20 protection degree protects against accidental contact and the ingress of small solid objects.

• Durability: Electrical endurance of 1 x 10^{5 cycles and mechanical endurance of 1 x 10}6 cycles guarantee long and trouble-free operation of the device.

• Easy installation: Designed for quick mounting on a standard TH-35 rail.

• Clear status: Contactor operating status indicator facilitates visual monitoring of device operation.

Additional information: the contactor power consumption is 6.4W, and the operating temperature is in the range of -25°C to +50°C. Screw terminals allow connection of wires with a cross-section of up to 16 mm². The insulation voltage is as high as 4kV, providing additional safety. The contactor meets the requirements of IEC 61095 standard.
