Cam switch disconnector 15A, Isolator 0-1 (3-pole) with signal path, in OB3 housing with lockable yellow/red front cover ŁK15-2.829\OB3ZC

Rotary cam switch – reliable switching in your installation

This three-pole rotary cam switch with a rated current of 15A is a solid solution for frequent circuit switching. Equipped with a 0-1 disconnector, it provides safe and convenient power switching. The design with a signaling circuit allows for easy monitoring of the circuit status, which is particularly important in industrial and automation applications. The OB3 housing with a key-lockable front (yellow/red) guarantees a high level of security and protection against unauthorized access.

Construction and application

The rotary cam switch LK15-2.829\OB3ZC is designed for continuous operation in a wide range of ambient temperatures (-25°C to +70°C). It is intended for mounting on a panel and is used for controlling motors, machines and electrical equipment. The ability to configure the number of segments (from 1 to 16) allows the switch to be adapted to specific installation needs. The robust construction and high resistance to environmental conditions ensure long-lasting and trouble-free operation.

Key features and benefits

• High reliability: Rated current of 15A and mechanical endurance of 3 million switching cycles guarantee a long service life.
• Safety of use: OB3 housing with a key-lockable front provides protection against accidental opening and unauthorized access.
• Versatility: The ability to configure the number of segments allows the switch to be adapted to different applications.
