Low-voltage complete devices series SPASSK-89

Low-voltage device (LVD) SPASSK-89 for currents up to 5000A is a panel of unilateral and bilateral service in metal cases with a fixed or withdrawable circuit breakers with air-insulated. NKU SPASSK-89 used as shields switchgear with voltage of 0.4 kV (RU-0.4 kV) substations, main switchboards (MSB) of industrial buildings, control panels motor loads.

NKU SPASSK-89 is suitable for power distribution of three-phase AC voltage up to 690V and 50 Hz in networks with isolated or grounded neutral protection against overload and short circuit protection, automatic input of a reserve (AVR), and also for control, measuring and signaling.


Low-voltage complete devices SPASSK-89 - economical, practical, standard solution for industry with continuous technological processes, administrative and civil purposes.

Modular technology of the device allows to optimally adapt the installation SPASSK-89 under the requirements of the customer.

The use of high quality switchgear ensures reliable operation and increases the service life of equipment and ensures the safety of staff. New technology roll-out elements based on the principle of "clamping, not cutting contact of the blades in the tyre" eliminates contact wear.
