Cam switch disconnector 100A, 0-1 switch (3-pole) with signal path, in OB18 housing with yellow/red front. SK100-2.829\OB18C

Cam switch – reliable switching in your installation

This three-pole cam switch SK100, in OB18 housing with a yellow-red front, is a solid solution for frequent switching of electrical circuits. Designed for both professional and home use, it combines high mechanical strength with safety. The OB18 housing provides protection against external factors, and the clear color coding makes identification and operation easier.

Characteristics and application

The SK100 switch with a rated current of 100A is perfect for electrical installations requiring frequent load switching. It finds application in controlling motors, lighting, heaters and other electrical devices. Thanks to its high resistance to wear and stable parameters, it guarantees long-term and trouble-free operation. In combination with a 0-1 disconnector, it allows for safe isolation of the circuit during maintenance or repair.

Key features and benefits

• High mechanical resistance: Designed for intensive use – withstands up to 3 million switching cycles.

• Wide voltage range: Possibility of use in installations with voltage up to 690V AC.

• Safety of use: Protection class IP65 guarantees protection against dust and water jet, which increases safety in difficult working conditions.

• Resistance to environmental conditions: Operation at temperatures from -40°C to +70°C ensures reliability even in extreme conditions.

• Easy identification: Yellow-red front makes quick identification of the switch function easier.

• Universal mounting: Possibility of mounting on a panel (□68 hole) provides installation flexibility.

• Large wire cross-section: Support for wires with a cross-section of up to 35mm² (rigid) and 25mm² (flexible) allows connection of most typical installations.

• Short-circuit protection: Rated short-circuit making current Icm is 2.5kA, providing additional installation safety.

Technical parameters in practice

The rated continuous current (Iu) is 100 A, which means the maximum current that the switch can conduct without overheating. The rated insulation voltage (Ue) is 690 V – the maximum voltage at which the switch retains its insulating properties. The rated short-time withstand current (Icw(1s)) is 1.7 kA, which determines the switch's ability to withstand short-term overloads. Protection class IP65 guarantees protection against dust and water jet – ideal for outdoor or humid environments. The operating temperature range from -40°C to +70°C enables operation in difficult temperature conditions.

Remember that choosing the right switch is key to the safe and reliable operation of the entire electrical installation!
