ABB offers a complete line of low voltage replacement breakers based on the world class EMAX breaker technology for ABB / ITE / BBC / Gould / Brown Boveri ( K-Line®, K-Line® Plus, K-Don, FBK, MB, LK) and most major manufacturers: Siemens / Allis-Chalmers, Federal Pacific, General Electric, McGraw-Edison, Westinghouse.
Roll-In replacement
Low voltage roll-in replacement for ABB/ITE Type LK
ABB replacement circuit breakers provide increased safety, reliability, convenience and cost effectiveness. They are interchangeable and can be inserted directly into existing switchgear, minimizing downtime in critical applications with minimal cubical modifications. Easy to perform maintenance due to innovative design
New breaker elements with new trip units improve interruption performance, increase interval required to perform preventive maintenance and improve equipment protection
All electrical accessories are AC and DC powered, allowing reduced stock levels and avoids costly mistakes during installation. Current transformers are extremely easy to replace. Each element pole is independently isolated, guaranteeing total isolation between phases, phases and neutral, and to earth
Cradle-in-Cradle EMAX Cradle-in-Cradle replacement breaker for ITE Type MB16
The cradle-in-cradle replacement is an increasingly popular low voltage option, because it provides the ability to standardize on the ABB EMAX circuit breaker for all low voltage replacements regardless of the switchgear manufacturer. The ABB unique proprietary cradle-in-cradle insertion system is a double interface frame with inner and outer interfaces. The outer interface easily mounts physically and electrically in the switchgear cubicle minimizing downtime. The inner interface matches up with the EMAX draw out breaker, allowing for quick and easy installation and removal.
The benefits of the ABB low voltage cradle-in-cradle replacement circuit breakers include:
- Easy to standardize on EMAX and reduce inventory across different switchgear types
- Simplifies personnel training and increases personnel safety through standardization
- Fits into and strengthens breaker cubicles that may have settled or shifted over time
- Allows for the replacement EMAX breaker to easily rack into and out of the cubicle
- Avoids misalignments of circuit breaker connections
Direct Replacement EMAX direct replacement breaker for GE Type AKK
A direct replacement low voltage circuit breaker uses an EMAX circuit breaker that is mounted directly into the existing switchgear cubicle. The mounting is a “fixed in place” physical mount, both electrically and mechanically. Direct replacement circuit breakers of the same type are interchangeable with each other.
New Switchgear Doors
New low voltage replacement circuit breakers are provided with new switchgear doors that fit the dimensions of the EMAX circuit breaker. ABB replacement doors meet or exceed the original switchgear designed doors and include:
- Original door ventilation provisions
- Standard door mounted escutcheon that frames the circuit breaker
- Optional lockable hinged clear acrylic cover available to go over the EMAX circuit breaker front panel
