• ‘Time delayed’ trip characteristic for RCD devices with trip threshold >30mA: prevents RCD being tripped by
charging currents of capacitors and parasitic capacitances when appliance is switched on.
• ‘Leakage current protection, Type SI’ trip characteristic for RCD devices with trip threshold >30mA: insensitive to
nuisance tripping.
Circuit Breakers
• Establishments with standard (Type ‘B’) circuit breakers are sensitive to ‘surges’ which occur on switching on
freezers, refrigerators and other catering equipment, including microwave combination ovens. Because of this, a
Type ‘D’ circuit breaker (designed specifically for this type of equipment) must be fitted. An individual, suitably
rated circuit breaker should be fitted for each appliance installed.
Low impedance electrical supply
• This commercial combination microwave oven complies with EN 61000-3-11. However, when connecting sensitive
equipment to the same supply as the appliance, the user should determine in consultation with the supply
authority, if necessary, that a low impedance supply is used.
Electrical supply
• The e1s microwave combination oven is only available as a single-phase model and is designed to draw 13 amps
maximum in all configurations, as shown in Table 2.2.
