EARTHING + LIGHTNING PROTECTION

ROUND UP

Integrated electrical system as modern and stylish design. 90 ReStart devices restore power supply quickly from automatic circuit breaker trips, but only after checking the system status. In addition, the Autotest function periodi- cally tests the functioning of the residual current circuit breaker protection without disconnecting the system from the power supply. The range includes two pole and four pole versions. The 90 RCD range includes the MDC monobloc compact residual current circuit breaker with overcurrent protection, the BD and BDHP add-on modular residual current devices for MT and MTHP minia- ture circuit breakers and the SD residual current circuit breaker. The 90 AM range consists of auxiliaries for circuit breakers and many modular accessories for protection, command, programming, measurement and signal- ling in electric systems. The LST surge protection range guar- antees excellent protection of loads and power distribution systems. The 47 CVX range of distribution boards is available in bothmodular andmonobloc systems from

GEWISS , represented locally by ACDC Dynamics , produces systems and com- ponents for low voltage electrical installa- tions globally. The fact that development is seen as a constant management feature has permitted GEWISS to assert itself as a market leader, offering an integrated elec- trical systemwith over 20 000 products for Domotics, Energy and Lighting. Gewiss’s protection system is com- posed of products which have synergy and perfect integration among each other, such as the innovative 90 ReStart range (automatic reclosing devices), the 90 MCB and 90 RCD ranges (modular circuit breaker for circuit and residual current protection) and the 47 CVX range (metal distribution boards). An integrated range of products which can meet every need according to the application type, from residential to the industrial and which can guarantee quality and safety in step with market requirements. The advantages of GEWISS system are several, practical compatibility of homogenous products, simple and quick planning, installation and maintenance of the system, as well

160 A to 3 200 A. In both surface or flush mounting types, these boards are avail- able in a variety of IP ratings to suit most applications. Thanks to the extractable frame and quick connection of brackets, rails and functional profiles, the 160 A board allows quick assembly. Because the 630 A boards are based on a ‘completely open structure’, board wiring operations are quick and easy. Enquiries: Nelen Govender.Tel. +27 (0) 10 202 3300 or email neleng@acdc.co.za
