Rotary circuit breakers and disconnectors

Rotary switches and disconnectors - key elements of electrical installations

Rotary switches and disconnectors are the basis for safety and control in electrical systems.   At Onninen we offer a wide selection of these essential components. Our range includes products from renowned brands such as Spamel, Eti, Eaton, Apator and ABB. Each of these manufacturers stands out for its reliability and innovation.

We often hear questions about the differences between different types of switches. We explain that the main categories are cam switches, 0-1 switches, and specialist switches. Each type has its own unique application and characteristics. 0-1 switches are available in 1 to 4 pole versions. They are used to safely disconnect circuits under load.

Specialized solutions in the category of rotary switches and disconnectors

Our offer also includes three-phase starter switches. They offer positions 0, Y and A.   They are essential for starting high-power electric motors.   L-0-P direction change switches are the perfect solution for machines requiring reversing. They allow easy change of the engine's direction of operation.

For more complex installations, we recommend power source switches. They are available in 3- and 4-pole versions. They allow for quick switching between different energy sources. This is a key element in emergency power systems. They guarantee the continuity of critical equipment.

• CLBS disconnectors (25/40/63 3P) - compact and efficient
• Star-delta cam switches (25/40A) - ideal for starting engines
• 6.5 kW (20A) cam switches - universal use

Our experience shows that selecting the right circuit breaker or disconnector is crucial. It affects the safety and efficiency of the entire installation.   When selecting, take into account the voltage, rated current and number of phases.   The operating conditions of the device are also important. Industrial and domestic installations have different requirements.

Practical applications of rotary switches and disconnectors

In everyday practice, we observe various applications of these devices. In the food industry, cam switches control production lines. They provide precise control over processes. In car workshops, L-0-P switches operate lifts and diagnostic machines. They ensure safe work of mechanics.

Recently, we used CLBS disconnectors in a project for a large logistics center. They provided effective overload protection for transport systems. In another case, in a modernized sewage treatment plant, we used power source switches. They allowed for a smooth transition between main and emergency power supply.

Rotary switches and disconnectors are not just elements of the installation. They are a guarantee of safety and reliability.   In the case of office reorganization, we most often reach for compact 0-1 disconnectors. They are ideal for controlling lighting and air conditioning in individual zones. For small workshops, we recommend universal cam switches with a power of 6.5 kW. They are useful for operating various machines and tools.

Many customers ask us about energy-saving solutions. In response, we present modern switches with an automatic shutdown function. They reduce energy consumption during periods of inactivity. This is especially important in large production halls or warehouses. It translates into significant savings over the course of a year.

• Industry: Cam switches for production line control
• Workshops: L-0-P switches for operating specialist equipment
• Offices: 0-1 switches for lighting and air conditioning control
• Logistics centers: CLBS disconnectors to protect transport systems

Onninen recommends special attention to the quality and certification of products. All of our rotary switches and disconnectors meet strict European standards. This guarantees their reliability and long-term operation. In addition, most models have IP65 protection. This ensures resistance to dust and moisture.

In case of specific requirements, we offer technical advice. Our experts will help you choose the best solutions for your specific needs. We take into account both technical and economic aspects. Thanks to this, each customer receives a product that is perfectly tailored to their expectations.

Rotary switches and disconnectors are the foundation of a safe and efficient electrical installation.   At Onninen, we understand their key role. That is why we are constantly expanding our offer with the latest solutions. We invite you to familiarize yourself with the full range available in our branches and online store.
