Power Circuit Breakers

for safety and protection

TemBreak 2
 
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.

10 Reasons to Use TemBreak 2
         
1. FIELD-INSTALLABLE ACCESSORIES 2. SAFETY LOCK FOR
PLUG-IN VERSIONS
3. SMALLER 1000A MCCB 4. SUPERIOR TEMPERATURE PERFORMANCE 5. COMPACT CHANGEOVERS
Accessories can be fitted by  the switchboard builder or added by the end-user.

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. The new 1000A MCCB is only 213mm high by 210mm wide - the same size as an 800A MCCB. This offers a cost-effective and space-efficient solution for large loads.

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.

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.

   
6. CIRCUIT BREAKER WITH INTEGRAL RESIDUAL CURRENT PROTECTION (CBRs)
7. DIRECT OPENING
Terasaki CBRs deliver integrated protection from earth leakage faults, overloads and short-circuits in one device. Ideal for the mining industry, temporary site supplies, heavy industry and commercial building use.

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. 75MM WIDE MCCB UP TO 160A, 40KA 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. Save space and save money with our TemBreak 2 Lite 160A frame breaker 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
