Independent (off-grid) isolating switch, 3-pole, handle on drive shaft RA 160 P3/R Un: 690 V~ In: 160 A Ui: 1000 V 63-822982-051

Isolator switch – reliable power disconnection

This three-pole isolator switch with an independent (knife) drive is a key element ensuring safe and controlled disconnection of electrical circuits. Designed to operate at 690 V~ and 160 A, it is a solid solution for both professional installers and end-users. The construction with a handle on the drive shaft enables convenient and intuitive operation.

Functionality and application

The RA 160 P3/R isolator switch is perfect as a main switch in electrical installations. Its task is to ensure complete disconnection of the circuit, which is essential during maintenance, repair or modernization work. The possibility of mounting on a plate increases the flexibility of the installation, and the screw connection of the main contacts guarantees reliable and durable connections. The rated continuous current of 160 A allows for safe operation with medium-power loads.

Safety and operating parameters

The isolator switch has been designed with user safety in mind. The rated operating voltage is 690 V~, and the maximum operating voltage Ue AC is also 690 V. The withstand current Iq is 8 kA, providing protection against the effects of sudden overvoltages. The IP00 protection class indicates that the device is intended for use in dry and clean rooms. It is important to note that the isolator switch does not have a locking mechanism, which requires caution during operation. Its construction does not provide for mounting in distribution boards or as an emergency switch or safety/maintenance isolator.
