Cam switch disconnector 63A, 1-0-2 switch (3-pole), in OB4 enclosure with yellow/red lockable front plate ŁK63-3.8380\OB4ZC

Universal cam switch for demanding applications

This three-pole cam switch with a rated current of 63A is a reliable solution for switching electrical circuits. Designed for both professional and end-user applications, it ensures safe and efficient operation in various conditions. The 1-0-2 design allows for flexible load control, and the robust housing protects against environmental influences.

Construction and application

The cam switch LK63-3.8380\OB4 with a closable front (yellow/red) is a modular element designed for mounting on a rail or directly in an enclosure. It is used in electrical installations of residential, commercial buildings and light industry. Thanks to its high resistance to atmospheric conditions (IP65 protection class of the front), it is ideal for use in places exposed to moisture and dust. The ability to close the front further increases safety, especially in public places.

Key features and benefits

• High reliability: Continuous rated current of 63A and high mechanical strength (3 million switching cycles) guarantee long-lasting and trouble-free operation.
• Safety: IP65 protection class protects against moisture and dust, and the ability to close the front protects against unauthorized access.
• Versatility: The 1-0-2 design enables a wide range of applications – from simple lighting circuits to more complex control systems.
• Resistance to external conditions: A wide range of operating temperatures (-40°C to +70°C) allows the switch to be used in harsh environmental conditions.
• Easy installation: Screw connection of the main contacts ensures quick and secure connection of cables with a cross-section of 4-10 mm².
• High switching power: Rated operating power for AC-3 is 20 kW at 400V, allowing operation of even demanding receivers.
• Impulse strength: Withstand impulse voltage Uimp is 6kV which ensures resistance to overvoltage.

Technical parameters in practice

The rated continuous current of 63A means that the switch can safely operate with a load of this value for a long time. The rated switching power Pe in category AC-3 (20 kW at 400V) demonstrates its ability to switch on and off electric motors and other inductive devices. Short-circuit current Icw(1s) of 1.2 kA indicates resistance to short-term overloads, which increases the safety of the installation. The housing material - plastic - provides insulation and corrosion resistance.
