Product Model
250-422
Selling Points
- 1The WAGO 250-422 terminal block uses CAGE CLAMP technology for automatic clamping, ensuring a tight and damage-free connection.
- 2The uniquely curved current bar and flat clamping face provide a high retention force, even under pullout forces.
- 3Tested for shock and vibration up to 2000 Hz with accelerations up to 109 G, meeting VDE 0611 vibration test requirements.
- 4Designed to limit temperature rise under continuous load at nominal current, ensuring reliability in various environments.
- 5Suitable for various applications, including rail-mounted configurations, with jumper contacts that can be marked and removed as needed.
