High performance

1. No duration upto 55°C
Contactors are suitable for operation in service temperature up to 55°C without derating. This avoids selection of higher rated contactor, thereby reducing cost.

2. Long Life
Superior design of current carrying parts, contact system and the magnet system increases the reliability results into higher electrical and mechanical endurance.

3. High short-time rating
Contactors have a high short-time rating, which makes them suitable for applications having high starting currents and long run-up times.
