Cam switch disconnector 63A, 1-0-2 switch (3-pole), in OB3 enclosure. ŁK63-3.8380\OB3

Universal cam switch for demanding applications

This three-pole cam switch with a rated current of 63A is a robust solution for manual switching of electrical circuits on and off. It is ideal for applications requiring reliability and frequent switching, such as controlling motors, transformers or other medium-power electrical devices. The design with a "0" position provides additional safety during maintenance and repair, allowing complete isolation of the circuit.

Design and functionality

The switch is made of high-quality plastic, which guarantees its durability and resistance to mechanical damage. The IP65 protection rating provides effective protection against dust and water jets, allowing installation in harsh environmental conditions. Screw connection of the main contacts ensures a secure and reliable connection of the wires. This model is supplied as a complete device in OB3 housing, ready for mounting.

Operating parameters and compliance with standards

The rated power for AC-3 at 400V is 20kW, making it suitable for industrial and commercial applications. The switch meets the requirements of EN 60 947-3:1992, confirming its safety and compliance with applicable standards. The continuous rated current Iu is 63A, and the rated short-circuit current withstood by the switch is 1.2kA – important parameters when designing electrical installations. Thanks to this, it can be used in installations with higher loads without the risk of damage to the device.
