Circuit breakers for rack-mount applications

The new 1U Series Slimline is a range of hydraulic magnetic circuit breakers developed especially for rack-mount and limited space applications for control and instrumentation designers

The new 1U Series Slimline, a range of hydraulic magnetic circuit breakers developed especially for rack-mount and limited space applications, promises control and instrumentation designers, equipment manufacturers and end-users increased power density with reliable performance.

Manufactured by Eaton Heinemann, the Slimline is available exclusively in the UK through Rowe Hankins Components.

The Slimline has the performance of a full sized hydraulic magnetic breaker in a 1U miniaturised package.

Positive operation is assured by a patented snap-action movement.

This controls the contacts through a stored energy mechanism closing them in one swift action when the operator moves the handle to 'on'.

This advanced feature helps prevent premature contact failure, increases efficiency and permits higher current ratings.

In addition to higher device packing density, the compact size gives designers much more flexibility.

Units can be supplied calibrated against medium, short or instantaneous delay trip curves.

Nuisance tripping is avoided with one hundred percent rated performance, even at raised temperatures and with current in-rush.

1U Series Slimline circuit beakers are available in current ranges 1 to 100 Amps and are rated 80Vdc and up to 240Vac.

They perform reliably in temperatures from -40 to +80 degrees Celsius.

The units are CE marked and accepted by Underwriters Laboratories as compliant with UL489 for branch circuit protection.

Toni Hankins, managing director of Rowe Hankins Components, commented: "The addition of the Heinemann 1U Series Slimline, means UK instrumentation designers, equipment manufacturers and end users can meet all their circuit breaker needs in one place - and all backed by our experience technical service staff.".
