Disconnect switch On/Off In=100A P=50kW P3-100/I5/SVB/HI11 207378

Main and isolating switch – reliable power disconnection

This On/Off switch with a rated current of 100A and a power of 50kW (at AC-23, 400V) is a robust solution for safely disconnecting electrical circuits. The device's design, compliant with IEC/EN 60947-3 standards, ensures reliable operation in various installations. It is a complete device in an enclosure, ready for mounting.

Functionality and application

The device functions as a main switch, safety switch, and maintenance switch. This makes it suitable for both industrial installations, public buildings, and homes. The red handle with a locking ring (lockable with three padlocks) increases work safety by preventing accidental switching on of the circuit during maintenance or repair. The locking mechanism is particularly important in applications requiring a high level of safety. The manual drive acts directly on the contacts, ensuring a positive and forced disconnection.

Technical characteristics and construction

The switch features a three-pole design and the possibility of plate mounting. It has one normally open and one normally closed auxiliary contact, enabling integration with control and signaling systems. The IP65 degree of protection on the front side guarantees resistance to dust and water ingress, which is important in harsh environmental conditions. Made of high-quality materials, it ensures long-lasting and trouble-free operation. The rated continuous current (Iu) is 100A, and the withstand short-circuit current (Icw) is 2kA – these parameters demonstrate its ability to operate in demanding overload conditions. Screw connection of the main contacts ensures a secure and durable connection of the conductors.
