TemBreak 2 is the Ultimate Safety Breaker. It has specifications which exceed international standards for safety.

Direct opening action - recommended by IEC standards for machinery safety - is a feature of most models.

A unique safety lock system for plug-in MCCBs ensures that the MCCB cannot carry current while being fitted or removed.

Accessories can be fitted by  the switchboard builder or added by the end-user. All internal accessories are common for TemBreak 2 MCCBs.

External operating handles and motor operators can be rapidly fitted using the locking pegs. It takes less than 10 seconds to secure a handle or motor to the MCCB – a great time saving compared to alternative products.

All accessories are endurance tested to the same level as the host MCCB.

The plug-in MCCB is locked to the base when the toggle is ON. It cannot be removed unless the toggle is OFF or TRIPPED. The safety lock prevents a trip occurring as the MCCB is being removed from the base. Door cutout patterns for external operating external operating handles are symmetrical, even when breakers are mounted in opposite directions.

All TemBreak 2 MCCBs are fully rated for use at 50ºC. Overheating is the most common cause of failure in electrical switchgear. You can reduce the likelihood of overheating by using switchgear with superior temperature performance.

All current ratings up to 630A can be supplied in 2 sizes: the 250A and 630A sizes.

Tembreak2 125A
The compact 125A size offers the same features and performance but with reduced dimensions and cost.
 
6. COMPACT CHANGEOVERS
7. DIRECT OPENING
The mechanical interlock is installed on the front of the MCCB, and is compatible with motor operators and external operating handles. An automatic changeover system can be assembled in a few minutes by a switchboard builder or end-user.

Under the heading “Measures to minimise the risk in the event of failure”, IEC 60204-1 Safety of Machinery-Electrical Equipment of Machinery includes the following recommendation:

“-the use of switching devices having positive (or direct) opening operation.”

8. UNSURPASSED FLEXIBILITY 9. CUSTOMISED TRIPPING TIMES 10. VISUAL SAFETY

Overload protection is adjustable between 63% and 100% of the rating. Short-circuit protection is adjustable on all thermal magnetic models. Short-circuit protection settings are suitable for motor starting on all models, including the compact 125A frame. If you require a characteristic which is not available as a preset on our electronic protection unit, send us the details and we will program a customised characteristic to suit your application. (Within certain limits - Contact us for details). Coloured indicators display the ON or OFF status. The indicators are fully covered if the breaker trips, and black is the only visible colour.
 

These features offer easy and safe installation and operation of MCCBs
