01.03 Additional modular devices

01.03.01 Switch disconnectors VN-32

01.03.01 Switch disconnectors VN-32

VN-32 switch disconnector are switching device without protection functions. From functional point of view, the VN-32 are knife switches with double break of contacts that prevents occurrence of leakage even under environmental conditions of elevated humidity. Switch versions for 100A have two contact bridges working in parallel in order to improve reliability of contacts and limit heat loss at contact junctions. The switches do not have arc suppression elements and cannot be used for switching on/off of capacitance and inductance loads.
01.03.02 Surge protective devices OPS1

01.03.02 Surge protective devices OPS1

Surge protective devices OPS1 are intended for protection of internal distribution networks of residential and public building from lightning and surge overvoltages. Correspond to the requirements EN 61643-11.
01.03.03 Accessories of modular series

01.03.03 Accessories of modular series

The KDU60 serves for obtaining information on status of VA47-60 circuit breakers in process automation systems or protection of individual facilities. The KDU60 has functions of auxiliary contact and position indication for the circuit breaker or RCCB resetting mechanism. The device comprise two switchover contacts: status contact (SC) and status|alarm contact (SC|AC). The contact SC|AC works depending on position of function selector: either as status contact or as alarm contact.
01.03.04 Modular contactors KM

01.03.04 Modular contactors KM

KM type module contactors are intended for use in AC networks of 400V (50Hz) and serve for commutating low inductance loads with rated currents up to 63V. They are applied for automation and control of various technological processes including that of lighting, ventilation and conditioning systems.
