SD204/63 disconnector 2CDD284101R0063

Isolator switch – reliable disconnection and safety

This four-pole isolator switch SD204/63 from ABB is a key element of any electrical installation, providing effective circuit disconnection and safety during maintenance work. It is a basic protection that, in conjunction with fuses, protects the installation and connected devices from the effects of short circuits and overvoltages. It is ideal for use in distribution boxes as a main power switch.

Functionality and parameters

The SD204/63 isolator is characterized by a rated current of 63A and a rated voltage of 440V. It occupies 4 module widths, which facilitates installation in standard distribution boards. Short-circuit strength at 25 kA guarantees its reliability even in difficult working conditions. The IP20 degree of protection provides basic protection against contact and ingress of solid objects.

• Four-pole design: allows for complete disconnection of the circuit.

• Rated current 63A: suitable for protecting circuits with medium loads.

• Width 4 modules: compact dimensions make it easy to install in tight spaces.

• Short-circuit strength 25 kA: high resistance to damage caused by short circuit.

• Installation depth 69 mm: allows adaptation to different types of distribution boards.

• Rated voltage 440 V: versatility of use in various installations.

Installation and application

The isolator is designed for mounting on a TH35 rail, which ensures stability and ease of installation. Remember that installation and connection should be performed only by a qualified electrician, observing all safety precautions – disconnect the power before starting work!. The risk of electric shock and damage to the installation is real with incorrect installation. The device is made of high-quality materials, which guarantees long-lasting and trouble-free operation. The gray color of the cover provides good visibility in low-light conditions.
