Disconnect switch ON-OFF, 3-pole + N, 40A, in IP65 enclosure, red-yellow knob with padlock lock P1-40/I2/SVB/N 199911

Universal isolator with lock – safety and control in one device

This isolator, with a rated current of 40A and a 3-pole design with neutral (3P+N), is a robust solution for safely disconnecting electrical circuits. The enclosure with an IP65 protection rating guarantees reliable operation even in harsh environmental conditions – moisture, dust or dirt are not a problem. This makes it ideal for use both indoors and outdoors.

Functionality and application

The device functions as a main switch, emergency stop switch and maintenance isolator, offering versatility in various installations. The red-yellow knob with the possibility of fitting a padlock is an additional safety feature, preventing accidental or unauthorized switching on of the circuit. The locking mechanism ensures stability of the knob setting. It is made in the form of a complete device in an enclosure, ready for mounting.

Parameters and capabilities

The isolator is characterized by a high switching capacity – up to 22 kW at 400 V (AC-23). The rated continuous current is 40A for AC-21 and AC-23 and 40A for AC-3. The withstood short-circuit current Icw is 0.64 kA, and the rated conditional short-circuit current Iq is as high as 80 kA – which proves its resistance to overloads. The possibility of operation at a rated voltage of 690 V expands the range of applications of the device. The connection of the main contacts is made using screw connections, which ensures a secure and durable connection of the wires. The rated current is 40A, and the short-circuit capacity Iq is as high as 80 kA, which proves its resistance to overloads. The rated power AC-23 at 400V is 22 kW, and AC-3 is 15 kW. The IP65 protection rating guarantees reliable operation in harsh environmental conditions, and the number of poles is 4 (3P+N).

The design of the device allows for safe and efficient disconnection of electrical circuits in various industrial and construction applications. It is a reliable tool for installers and a guarantee of safety for end users.
