Key features and benefits

Description

The SN236 series is a fire resistant high power feedthrough ideal for engine and APU applications.

Ideally suited to withstand harsh environmental conditions, the SN236 series prevents the spread of fire due to ceramic insulators (resistance to 1100°C during 15 minutes) and demonstrate  high temperature resistance (up to 200°C) as well as pressure resistance (leak rate <10-6 atm.cm3/s at 1 bar pressure difference).

The SN236 series success is due in part to high power lug terminations for aluminum and copper cables (up to 350 A at 600 Vrms) with an umbrella designed to prevent condensation that causes arching.

Compared to “feeder” solutions (receptacle + plug + 2 backshells), the SN236 series is a time-saving interconnect solution.

Custom designs can be done to adapt your specific current, contact orientation or temperature.
