Release curve and selective protection

The MEGATIKER series offers multiple release curves to ensure coordinated protection with upper and lower level equipment.

1. Thermal magnetic release curve

Overload protection: bimetallic strip with cold and hot characteristics

Short circuit protection: electromagnetic trip, instantaneous action

Typical curves: M1 160, M2 250, M3 series M4 630、M5 1600

2. Electronic release curve

Long delay (L): Ir and tr are adjustable to achieve precise overload protection

Short delay (S): Isd and tsd are adjustable to achieve selective protection

Instantaneous (I): Ii fixed or adjustable

Ground fault (G): Ig and TG are adjustable

3. Logic and dynamic selectivity

Logical selectivity: achieved through communication between electronic release devices, ensuring complete upstream and downstream selection

Dynamic selectivity: By adjusting the trip delay, achieve high-level selectivity
