SACE Emax 2
ABB SACE Emax 2 combines circuit protection with functions for managing low voltage power distribution. Depending on the selected version and trip unit, it supports protection, measurement and energy management for industrial and commercial electrical systems.
The integrated functions support different network conditions, including load shedding, power control, automatic transfer switching and interface protection. The device can connect to automation and energy management systems through a choice of communication protocols. ABB Ability™ electrical distribution services support monitoring, operation and ongoing development.
SACE Tmax T
This circuit breaker range includes three and four pole models with ratings up to 3200 A. Fixed, plug-in and withdrawable configurations are available, including T4, T5, T6 and T7 sizes. Compact designs provide high short circuit breaking capacity at different voltage levels. Thermal magnetic and electronic trip units support AC and DC applications as specified for each model. Replaceable trip units allow upgrades while retaining the breaker body, and electronic protection functions support selective fault clearing.
SACE Tmax XT
ABB SACE Tmax XT moulded case circuit breakers combine protection functions with flexible installation and connectivity options. Seven frame sizes cover applications up to 1600 A. Different trip units and configurations allow the breaker to be matched to the system requirements. Connectivity functions support remote monitoring and integration into modern facility and energy management systems.
