The Basics of Circuit Breaker Maintenance | EC&M bottles require very little maintenance when compared to air-magnetic contact assemblies. The contact moves only about ½ in. in the vacuum bottle, and the opening springs are much lighter. This reduces wear on the assembly and also reduces the weight, because heavy metal supports and frame can be decreased.
