Electronic pulse stretcher The electronic pulse stretcher, type C27extends the momentary pulses to 50 ms, which offers the following advantages: Circuit-breakers and drives must not be disassembled for service and maintenance work see Disclaimer of liability, section 1. For the design and method of operation of the transport truck used, please refer to the instructions for the panel in question.

Polish to achieve a bright surface: When performing the following assembly steps, observe and comply with the instructions given for the panel used. Rated supply voltage Power consumption min. As standard, the aeeva is equipped with two auxiliary switches with 8 contact elements each. The circuit-breaker operating company is responsible for complying with the specified maintenance intervals and for performing maintenance according to the actual operating and ambient conditions.

Gas-insulated switchgear type 8DQ1, kV, 80 kA siemens.

Reliability, operator safety and the mechanical functions of the switching devices have been proved in endurance tests or under regular operating conditions. The safety provisions of chapter 1.

Only approved Lubricants may be used section 9. The circuit-breaker must not be disassembled for maintenance work see Disclaimer of liability,section 1. Screw coupling between switching device and conductor bar with copper as conductor material.

Its contents do not constitute an offer for sale or advice on the application of any product referred to in it. Remove the cover plate of the circuit-breaker drive. The position indicator shows the switch position “ON” Table, Chapter 7. Observe the position indicator on the switchgear panel. Shipping units must be unpacked immediately after receipt. In case of frequent condensation or air pollution dust, smoke or corrosive gasesthe maintenance intervals must be adapted to the actual conditions.

The type designation is broken down in this example. If necessary, clean see Chapter 8. A rope with a diameter of 12 to 15 mm or a strap is required. Couple the transport truck to the panel.

Thus, the market requirements, especially regarding small functional compartments without additional solid insulating material in the panel to ensure dielectric strength, can be satisfied optimally. It must provide a sufficient heating performance to prevent condensation on the circuitbreaker.

Bolts and socket-head cap screws except slotted screws and nuts except selflocking nuts Table 2: Switch off the auxiliary voltage for the circuit-breaker drive and secure it against reclosing. Accordingly the design of our products may change at any time. Operation counter An operations counter has been integrated into the operator interface to furnish proof of the number of switching operations actually performed by the circuit-breaker.
