Cam switch disconnector 63A, 0-1 (3-pole) with signaling path, in OB2 housing with lockable yellow/red front ŁK63-2.829\OB2ZC

Cam switch – reliable control of electrical circuits

This three-pole cam switch, with a rated current of 63A, is a solid solution for switching electrical circuits on and off. Equipped with a 0-1 disconnector function, it allows for safe isolation of the load from the power supply. An additional signaling circuit increases the functionality of the device, and mounting in a durable OB2 housing provides protection against mechanical damage and external factors. The yellow/red front indicates the off state, which increases work safety.

Design and application

The SPAMEL ŁK63-2.829\OB2ZC cam switch is used in low-voltage electrical installations, both in industrial conditions (degree of pollution 3) and in commercial construction. It is ideal as a switch, disconnector, changeover switch or control switch. A wide range of operating temperatures (-40°C to +70°C) allows it to be used in harsh environmental conditions. It meets the requirements of PN-EN60947-3 and IEC 60947-3 standards, which guarantees its safety and reliability.

Key features and benefits

• High mechanical resistance: Durable construction and solid materials ensure long-term operation even in demanding conditions.
• Safety of use: The 0-1 disconnector function and clear indication of the off state (yellow/red front) minimize the risk of accidental activation or leaving it energized.
• Versatility: Can be used in various types of electrical installations – industrial and commercial.
• Wide operating temperature range: Allows operation in difficult climatic conditions (-40°C to +70°C).
• Compliance with standards: Meeting the requirements of PN-EN60947-3 and IEC 60947-3 standards confirms the safety and quality of the device.
• Resistance to external factors: Resistance to vibrations, shocks, damp heat and salt mist ensures reliable operation in various environments.
• Designed for mounting: The OB2 housing facilitates mounting and provides additional protection against damage.
• High switching power: Rated switching power up to 20 kW (at 400V) allows it to handle demanding loads.

Additional information regarding resistance to external factors (vibrations, shocks, damp heat, salt mist) confirms the high quality of workmanship and durability of the device. The cross-section of connection cables 4...10 mm² ensures compatibility with various types of electrical installations. The degree of protection IP65 guarantees protection against water jets and dust – particularly important in difficult working conditions.
