Disconnect switch RX3 40A 3P 419327

Isolator switch – reliable circuit disconnection

This three-pole RX3 isolator switch with a rated current of 40A is a robust solution for safely disconnecting electrical circuits. It is suitable for both domestic and industrial installations where reliable operation and compliance with standards are required. The device's design as a complete unit in an enclosure simplifies installation and provides protection against mechanical damage.

Features and application

The isolator switch is designed for mounting on a TH35 rail, ensuring quick and convenient installation in distribution boards. The possibility of connection using comb or pin busbars provides flexibility in choosing the method of connecting the wires. The device meets the requirements of IEC/EN 60947-3 standard and has a work category of AC 22A, which guarantees its reliability in typical applications. Its construction allows for complete isolation of the circuit, ensuring safety during maintenance or repair.

• The isolator switch provides a switching capacity of up to 16 kW at a voltage of 400 V, which is sufficient for most standard loads.
• The rated continuous current is 40 A, allowing safe operation with loads with constant power consumption.
• The device protects against the effects of short circuits and overvoltages thanks to the withstood short-circuit current at the level of 0.48 kA.
• The protection degree IP20 provides basic safety of use, protecting against finger contact and solid objects larger than 12.5 mm.
• Mounting on a TH35 rail guarantees quick and easy installation in the distribution board.
• The complete enclosure makes the device ready for immediate use after mounting on the rail.

Thanks to the possibility of completely isolating the circuit, this isolator switch is ideal for use as a main switch in an electrical installation. The gray actuating lever makes it easy to identify the device's status, and the lack of possibility to equip it with additional auxiliary contacts or releases simplifies the design and increases reliability. The device operates in a temperature range from -25°C to 70°C, allowing it to be used in various environmental conditions. Its mechanical durability is 20,000 cycles, which guarantees a long service life even with frequent use.
