Cam switch 4-pole 45° 20 A screw mounting K2H004ULH

Cam Switches – Reliable Control for Your Installation

This four-pole cam switch is a robust solution for frequent switching of electrical circuits. Designed by Schneider Electric, the K2H004ULH model combines durability, safety, and ease of installation. It performs exceptionally well in both industrial applications and demanding commercial installations.

This switch stands out with a high rated continuous current of 20 A and an AC-3 operating current of 8 A, ensuring reliability even under heavy loads. The four-pole design enables effective simultaneous control of multiple circuits. Thanks to a 45° rotation angle, it delivers precise and rapid switching.

Construction and Installation – Flexibility and Convenience

The K2H004ULH switch is designed for easy installation. The screw-terminal mounting system ensures stability and secure connections. The option for indirect mounting provides great flexibility in selecting the installation location. The IP40-rated enclosure protects against solid object ingress, enhancing safety in various environmental conditions. Constructed from durable materials, the switch is resistant to mechanical damage and ensures long-term operation.

Safety and Compliance with Standards

Safety is a priority. The switch features Class II protection, minimizing the risk of electric shock. Compliance with IEC 60947-3 (for power circuits) and IEC 60947-5-1 (for control circuits) confirms its high quality and adherence to rigorous standards. Additionally, it holds CSA and UL certifications, demonstrating its suitability for applications requiring specific safety regulations. The use of a 20A gG cartridge fuse provides additional protection against short-circuit damage.

Additional features worth noting:

• Electrical endurance: The switch withstands up to 200,000 cycles under AC-23 and AC-3 conditions, making it ideal for applications requiring frequent switching.
• Wide temperature range: Operation possible from -25°C to 55°C; storage range from -40°C to 70°C ensures reliability in harsh climatic conditions.
• “0” position: The presence of a “0” position enhances safety by enabling complete circuit disconnection.
• Mechanical durability: The switch withstands up to one million mechanical cycles, confirming its exceptional longevity and reliability.
• Connection type: Screw terminals ensure secure and stable wiring connections, minimizing the risk of loosening during operation.
• Extended rotary handle: Facilitates operation even in hard-to-reach locations or while wearing protective gloves.
