When the mechanical interlocking mechanism and two NC2 contactors form a reversible contactor, when the moving and static contacts of one contactor just touch, push the other contactor to make the two interlocking parts touch each other. Contact gap
NC2-115N~160N≥5.5
NC2-185N~225N≥5.5
NC2-285N~330N≥6
NC2-400N~500N≥6.5
NC2-630N ≥7
Mechanical life of mechanical interlock: 3 million times for NJLC-FF and NJLS-FF, and 2 million times for the rest
