ABB Electrical S2C-H6RU Miniature Circuit Breaker

Model Type: S2C Electrical S2C-H6RU Miniature Circuit Breaker

The action time of this unit is an inverse time limit characteristic. Dirt phase protection is an independent unit which will operate with a fixed delay of 600s when the phase sequence is wrong.

The unbalance and inverted phase protection units can be independently selected or withdrawn, e.g. the inverted phase unit can be withdrawn from use when the motor is allowed to operate in reverse phase sequence, so that there is no risk of the motor being damaged by a reversal of phase sequence.

In this case there will be no tripping due to motor reversal. The low-current unit is used for out-of-load protection of motors.

The unit is particularly suitable for equipment cooled by a constant flow of liquid, e.g. submersible pumps, where the cooling capacity of the motor is reduced when the flow is interrupted.

In this case the motor circuit will be tripped by the low current unit detecting the well. The start time totaliser is another measure to control the number of starts in a given period of time.

It can be set according to the permissible number of starts provided by the motor manufacturer.

The fault parameters recorded in the registers are very convenient and useful for fault analysis.

5000 and F critical spare parts Having critical spare parts on-hand can significantly reduce the downtime associated with excitation maintenance, 

forced outages, electrical and mechanical failures. 

As a minimum for operational reliability, it is essential to have critical spare parts and components readily available.

Excitation services provides you with a complimentary recommended spare part list and takes care of testing, 

maintaining and adjusting your spare part stock. We will also keep you informed about critical ageing processes of vital components.

Excitation Care

Power plants have three service needs in common:

emergency support, proactive maintenance and performance optimization. 

Excitation Care is designed to fulfill these common needs, is part of Power Generation Care and can be seamlessly integrated in these contracts. 

Excitation Care offers three different levels of support: Rapid Response, Life Cycle Management and Performance Improvement.

The Excitation Care program provides peace of mind and reassurance to your maintenance team.
