Cam switch disconnector 63A, 0-1 switch (3-pole), in OB4 housing with yellow/red lockable front ŁK63-2.8211\OB4ZC

Universal cam switch for demanding applications

This three-pole cam switch with a current of 63A is a reliable solution for switching electrical circuits. Designed for both industrial and building installations, it combines a robust construction with functionality, ensuring safe and efficient operation. Equipped with a 0-1 disconnecting mechanism, it allows for easy and reliable power disconnection.

Design and application

The switch is housed in a durable OB4 enclosure with a yellow-red locking front, providing high resistance to mechanical damage and external factors. The IP65 protection rating guarantees protection against dust and water jets, making it ideal for use in harsh environmental conditions. Designed for indirect mounting, it offers flexibility in integration with various electrical systems. Made of high-quality plastic, it is lightweight and easy to operate.

Performance and safety

The switch is characterized by a rated continuous current of 63A and the ability to switch loads up to 20 kW (AC-3 at 400V). It provides effective protection against overload and short circuit - like most circuit breakers in this class. Thanks to its high resistance to vibration and impact, it meets stringent safety standards. The knob mechanism provides convenient and precise operation. In addition, the high mechanical durability of 3 million switching cycles guarantees long-lasting and trouble-free operation of the device.

The rated switching power AC-3 up to 20 kW at 400V allows for operation of a wide range of devices. The rated short-time withstand current Icw(1s) is 1.2 kA, providing resistance to short-term current surges. A wide operating temperature range from -40°C to +70°C enables use in various climatic conditions. The possibility of connecting wires with a cross-section of 4…10 mm² ensures compatibility with various types of electrical installations. The IP65 protection rating guarantees protection against dust and water, increasing safety of use.
