The product is a rotary switch from Eaton's P1 product series, type P1-25/EA/SVB/HI11, designed as a main switch for industrial applications. It is intended for safe disconnection of electrical loads and for installation in enclosures. The switch features an emergency stop function, which can be locked in position 0 (Off), and is equipped with a red rotary handle and a yellow locking collar. The protection rating IP65 ensures dust and splash water protection, making it suitable for use in industrial environments. The rated current is 25 A, and the switch is 3-pole.

Applications

The switch is used in industrial electrical engineering, particularly in systems requiring safe and manual power disconnection. It is suitable for systems with a rated voltage of 400 V and a frequency of 50–60 Hz, with a rated power of 11 kW at AC-23A. The protection rating IP65 makes it suitable for use in environments with increased humidity or dust exposure, such as production halls or outdoor areas. The locking in position 0 enables safe shutdown, protected against accidental re-energization.

Functions and Equipment in Detail

The switch is equipped with a red rotary handle and a yellow locking collar, making the positions visually identifiable. The emergency stop function allows immediate shutdown in an emergency. The locking in position 0 (Off) ensures the switch cannot be accidentally turned on, which is important during maintenance or inspections. The 3-pole design enables disconnection of all three phase conductors, which is necessary for safety in three-phase networks.

Technology Explained Simply

The switch operates according to the principle of a load disconnector in accordance with IEC/EN 60947-3. The rated current of 25 A means it can continuously carry a current of up to 25 amperes without overheating. The protection rating IP65 protects against dust and splashing water, making it suitable for use in harsh environments. The emergency stop function is a safety feature that allows immediate shutdown to protect personnel or machinery from damage. The locking in position 0 (Off) is an additional safety feature that prevents re-energization.

Compatibility and Accessories

Various accessories are available for this switch to extend its functionality. These include additional front plates in different languages (e.g. German/English, French), toggle handles in various colors (e.g. red, black), terminal covers, locking components with N-/PE connection, neutral conductor terminals, and locking extensions. These components can be added according to the system requirements to optimize operation or integrate additional safety features. The accessories are specifically designed for the P1 series and ensure safe and compatible installation.

Mounting and Installation

The switch is designed for installation in enclosures. Mounting is typically done using fixing screws on the enclosure wall. Connections are made at the terminals, which are intended for connection to the wiring. The switch positions (On, Off, Emergency Stop) are clearly identifiable by the color coding of the rotary handle and locking collar, as well as by mechanical positioning. The locking in position 0 (Off) is activated by the integrated locking mechanism as soon as the switch is moved into this position.

Advantages in Operation

The switch offers clear and safe operation through visual identification of positions. The emergency stop function enables immediate shutdown in an emergency, increasing safety. The locking in position 0 (Off) protects against accidental re-energization, which is important during maintenance. The protection rating IP65 makes it suitable for use in harsh environments, and the 3-pole design ensures complete disconnection of the electrical load. Compatibility with various accessories allows adaptation to specific system requirements.

Standards and Regulations

The switch complies with standards IEC/EN 60947, VDE 0660, IEC/EN 60204, CSA and UL. It is classified as a load disconnector in accordance with IEC/EN 60947-3 and meets requirements for use in industrial systems. The protection rating IP65 meets requirements for use in environments with increased humidity or dust exposure. The rated power of 11 kW at 400 V and 50–60 Hz is suitable for typical industrial applications.

Accessories and Extensions

Various accessories are available for this switch to extend its functionality. These include additional front plates in different languages (e.g. German/English, French), toggle handles in various colors (e.g. red, black), terminal covers, locking components with N-/PE connection, neutral conductor terminals, and locking extensions. These components can be added according to the system requirements to optimize operation or integrate additional safety features. The accessories are specifically designed for the P1 series and ensure safe and compatible installation.

Safety and Operation
