Cam switch disconnector 63A, -4.8240 in OB18 enclosure with yellow/red lockable cover. SK63-4.8240\OB18ZC

Cam switches – reliable switching in your installation

The cam switch SK63-4.8240 is a solid device designed for safe and convenient switching of electrical circuits. Manufactured by Spamel, it combines a proven design with high-quality workmanship. This model, combined with the OB18 housing and a lockable front (yellow/red), provides not only functionality but also additional safety and aesthetic mounting. It is an ideal solution for both professional installers and end-users who value reliability and durability.

Construction and application

The cam switch SK63-4.8240 is a modular element, which means it can be easily integrated with other components of the electrical installation. It is designed to operate in circuits with a rated insulation voltage of up to 690V and a rated current of 63A. The design allows for mounting on a panel, and the OB18 housing provides protection against external factors (IP65 protection). The front locked with a key (yellow/red) further protects against unauthorized access and accidental adjustment. The device finds application in control panels, switchboards and other electrical installations requiring frequent circuit switching.

Key features and benefits

• High reliability: The design based on proven Spamel solutions guarantees long-lasting and trouble-free operation.
• Safety: The OB18 housing and lockable front provide protection against electric shock and unauthorized access.
• Versatility: The ability to mount on a panel and integrate with other electrical installation elements increases the range of applications.
• Mechanical durability: Designed for intensive use – withstands up to 3 million switching cycles.
• Resistance to external conditions: A wide operating temperature range (-40°C to +70°C) allows use in harsh environmental conditions.
• Suitable for different types of cables: Supports both rigid and flexible cables with a cross-section from 6 to 16 mm².
• Compliance with standards: Meets European standards regarding safety and quality.
• Protection against vibrations and shocks: Ensures stable operation even in demanding industrial conditions.

Technical parameters in practice

The rated switching current Ic of 63A allows handling most standard loads in electrical installations. The short-circuit withstand current Icw(1s) of 1.2kA provides additional safety in the event of a short circuit. The screw tightening torque of 2.0 Nm guarantees a secure electrical connection without the risk of damaging the terminals. The degree of protection IP65 means complete protection against dust and a water jet directed from any direction – which is particularly important in humid or dusty working environments. Protection class II provides additional safety by isolation from grounding.
