SCHNEIDER ELECTRIC iC60H A9F77216 + iSD A9A26927

Schneider Electric iC60H C16A Miniature Circuit Breaker with Auxiliary

Description

This is an Acti 9 iC60H miniature circuit breaker from Schneider Electric, complete with a factory-fitted or pre-assembled iSD fault signal contact. This 2-pole device is rated for 16A with a C-type tripping characteristic, providing robust protection against overcurrents and short circuits. The ‘H’ designation indicates a high breaking capacity of 10 kA, making it suitable for industrial and commercial environments where fault currents can be higher. The included iSD contact allows for remote monitoring of fault trips.

FAQ

Question?

What is the difference between the iC60N and iC60H models?

Answer:
The primary difference is the breaking capacity. The iC60N has a breaking capacity of 6 kA according to IEC 60898-1, while the iC60H model shown here has a higher breaking capacity of 10 kA, making it suitable for installations with higher potential short-circuit currents, typically found in commercial and industrial environments.

Question?

What is the function of the attached iSD auxiliary contact?

Answer:
The iSD (Indication Signalisation Defaut) is a fault signal contact. It provides a remote signal to indicate that the circuit breaker has tripped specifically due to a fault, such as an overload or a short circuit. It does not activate when the breaker is manually switched off, allowing for clear differentiation between manual operation and a protective trip.

Question?

Can this C-curve breaker be used for circuits with large inrush currents, like motors?

Answer:
A C-curve breaker is designed for general purpose applications, including resistive and inductive loads with low inrush currents (e.g., lighting, sockets). For circuits with high inrush currents, such as motors or transformers, a D-curve or K-curve breaker is typically recommended to prevent nuisance tripping on startup.
