Power relay withstands high peak inrush currents up to 800 A

18 May 2005 Switches, Relays & Keypads

A high-end member of the RT family, the Schrack RT-i Power high-inrush relay from Tyco Electronics is designed to handle peak inrush currents up to 800 A. With a rated carry current of 16 A, the relay is capable of switching a variety of capacitive and lighting type loads.

Key design features include a single normally-open (N/O) contact design with a tungsten pre-mate to absorb the inrush current energy and silver tin oxide carry contacts, reinforced insulation, ambient operating temperature to 85°C, 10 mm coil contact clearance, 5 kV dielectric strength and inrush peak current ratings of 800 A for 200 μs (fluorescent lamps) and 165 A for 20 ms (incandescent lamps).

Both monostable 400 mW DC coil and bistable/latching versions are available, with the bistable versions offering an optional manual operator switch to facilitate circuit test.
