Type Testing and Conformity
To offer conformity to IEC 60947-6-1 a manufacturer has to test their product in line with the ‘Type Tests’ and ‘Routine Tests’ that are fully set out in the standard and detailed in sub clause 188.8.131.52 Table 7. These tests are rigorous, as would be expected of a product which can have such an important function.
The tests in the standard include such things as Temperature Rise, Dielectric Properties, Making and Breaking Capacities, Electrical & Mechanical Operational Performance and Short Circuit Capacities.
Mertech manufacture three different types of Transfer Panels:
- Contactor Type - Series CC,
- Motor Operated Switch Type - Series PC
- Circuit BreakerType - Series CB.
For applications requiring to comply with the latest ‘Life Safety’ standards, Mertech manufacture a complimentary range of single and double manual by-pass switches. By-Pass switches are manual four pole transfer switches. They are designed to isolate the Automatic Transfer Switch with minimum interruption to the load supply.
Transfer Control devices
The transfer control devices can be designed to suit any application as long as the controls comply with the sequence and limits of operation as stated in the specification. A number of devices are offered on Mertech Automatic Transfer Switching Equipment. All have been tested and comply with the specification and some go well beyond the minimum requirements set out.
