Circuit breaker not suitable for continuous load of large inverters



Bosch GSH 27 VC Professional Breaker is the most Powerful Electric Breaker from Bosch! This Bosch cordless drill tool has decoupled handles and vibration-reduced hammer mechanism which reduces the vibration to just 8m/s². It consists of components made of aluminum and steel which increases the lifetime of the tool even when working under tough conditions. It has a high impact performance due to 62 joules of impact energy and 1000 blows per minute. It has ergonomic handles with soft grip and low center of gravity which ensures optimum handling of the tool. It also includes an anti-slip surface which prevents the tool from falling over.For more information, please visit our website: http://www.bosch-professional.com/middle-east/en/ Get in touch with us on Facebook here: https://www.facebook.com/BoschGlobalFollow us on Twitter here: https://twitter.com/BoschGlobal
