Eaton 90° Rotary Cam Switch, 20A, 690V AC - T0 Series - 024639 T0-2-1/E

Looking for a safe way to streamline the on-and-off switching of your electrical circuits? Use this rotary cam switch from Eaton. It has a manual switching thumb grip for safely controlling your system. When you turn the dial by 90°, it cuts the power supply to your circuit for easy maintenance and user safety in the event of a hazard. It has two positions that are clearly marked in black text on a white front plate for ease of operation. This unit is ideal for electrical engineering and industrial automation applications.

• Compact size of 48 (length) x 90 (width) x 48mm (depth) for installation in tight spaces

• High maximum voltage of 690V AC for use in high-powered industrial systems

• Screw terminal type for ease of installation

What’s a 'normally open' switch configuration?

A 'normally open' configuration indicates that the switch is turned off unless manually turned on. This means that no electrical current will flow unless the switch is in use.

Can I install this switch in harsh environments?

Yes. This switch features an IP65 (ingress protection) rating, which means that it’s protected against dust and low-pressure water jets. This makes it suitable for use in heavy-duty industrial environments.

Eaton Rotary Cam Switches - T0 Series

The T0 series of rotary cam switches and switch disconnectors from Eaton are compact and robust. Rotary Cam Switches can be used for many switching and control applications, for example as ON-OFF, main, main/control, or instrument switches. The device consists of a hand actuator, the switch unit and the mounting accessories. This range of cam switches is also suitable for use in applications where there is a need to manually power down and disconnect electrical equipment for servicing and maintenance by cutting the power supply to isolated parts of the circuit. These cam switches can also be used as safety switches.

With an IP65 degree of protection, the devices are suited to hard-wearing industrial environments with a rated uninterrupted current of up to 20 A. Available in four different mounting options (surface mount, flush-mount, rear mount, and service distribution board mount). These cam switches can be selected in a multitude of contact sequence configurations.

This professional range of cam switches offers corrosion resistance, weather sustainability, insulating material resistance to normal heat and fire due to internal electric effects and more. It comes with various advantages including high reliability, high adaptability, low power usage and makes the product efficient in its performance.
