Miniature Circuit Breakers

Series G - Miniature Circuit Breakers

Miniature circuit breakers, or MCBs shortly, protect an electrical circuit from damage caused by overload or short circuit.

 
The Series G, is GEs basic range of MCBs and covers a complete range of short circuit breaking capacities and tripping characteristics for residential (G30, G45 and G60) and industrial use (G100).
 

Features

• 3, 4, 6 and 10kA
• Characteristics B-C (G100, D also available)
• 1P,  1P+N (G60, G100), 2P, 3P and 4P versions available
