Gewiss DIN Mini Circuit Breakers 1P 20A C 4.5/6kA 1M

Product Features

• Miniature circuit breaker MT45 range
• The position of the releases on the front, with magnetic turns and opposing arc chute chambers, allows a notable reduction in arc time and short-circuit strain on the mechanism
• It has therefore been possible to halve the system and lighten the mechanism, which has short pre-arc times thanks to the reduced energy
• The new mechanism has been sized and optimised by means of a sophisticated planning, engineering and testing programme
• Manual control lever with a position coherent with the contacts, allowing the circuit breaker to be used as a switch disconnector (in compliance with Standard CEI 64-8)
• Toggle joint tripping mechanism with tripping accelerator for short-circuit condition
• Electromagnets for instantaneous short-circuit tripping
• Silver-graphite contacts to maintain electrical characteristics over time
• Magnetic turns in the arc chute chambers
• Arc chute chambers with 12 reeds in a ferromagnetic material
• Shell-type terminals with anti-loosening tightening system
