Abb Type R Circuit Breaker

Modified for use on all type r breakers and all esva recloser designs.

Abb type r circuit breaker.

Due to this it is abb s interest to develop new service solutions to keep the equipment under the best condition. Mechanism and compartment detail rear view latch check switch push to close bar spring charge m right closing spring manual charge device figure 5b. These designs are to be used for indoor applications. Mechanism front view.

The high voltage compartment the mounting provisions and the low voltage compartment. Some of the devices are the heaters charg ing motor trip and close coils and relays. Type r is used for applications at 15 kv or 27 kv and type v for applications at 38 kv. Abb s type v vacuum circuit breaker meets all applicable nema ansi.

Type r 27 kv instructions for vacuum circuit breaker created date. The low voltage internal circuitry connects the devices in the low voltage compartments with the con trol power. The type r and type v vacuum circuit breaker trays are the industrial application of the type r and type v outdoor circuit breakers. Together with the optional relaying and current transformers the breaker will sense an overload and automatically open.

Style 279c693g06 this is a complete mechanism. This breaker should be installed within the design limitations as described on. Abb s type r vacuum circuit breaker meets all applicable ansi nema standards. The type r mag vacuum breaker is a high voltage three phase device incorporating three vac uum interrupters gang operated by a magnetic actuator.

All components at line potential are contained in the high voltage hv section and are completely. Based on magnetic actuation the r mag has fewer moving parts and is mechanically simpler than breakers with traditional spring mechanisms. They are primarily used by utilities for. Type r vacuum circuit breaker 13.

It is the new mechanism with the new transfer link usable on all es esm and esv reclosers as well as newer design type r breakers and esva reclosers manufactured after march of 1983. The control for basic breakers is located in a re mote enclosure. Abb recognizes the industry s focus on safety and reliability and helps meet these goals with the r mag circuit breaker for medium voltage primary substations. Abb might be done or of the possible hazardous consequences of each.

The type r vacuum circuit breaker is made up of three basic sections. The operating mechanism ahma is one of the key components to ensure a high availability and relia bility of the circuit breaker elf sp.
