Series 4120 switches are single-pole, thermal circuit breakers with threadneck mounting, push/pull actuation, temperature compensation and high breaking capacity and optional auxiliary contact. They have a reliable switching behaviour due to an uninfluenced free tripping.
The special design allows use under extreme environmental conditions. Various dummies without electrical protection functions are available for mounting pre-installed wiring without consumers.
Typical applications:
Land, air and water vehicles
