250A Triple Pole 36kA Large Frame Size Moulded Case Circuit Breaker
- The moulded case circuit breakers are housed in fibre reinforced thermoset polyester that combines ruggedness, high dielectric and mechanical strength
- High quality silver alloy contacts (with elements of tungsten and graphite) ensure both high conductivity at point contact and minimal pitting during switching for a longer contact life
- Positive contact indication is by means of the operating lever position
