Posted on October 10, 2011

Sensata Technologies Inc. has introduced the SDLS and FDLS series switchable thermal circuit breakers for the truck, bus, specialty vehicle, electric vehicle and marine markets.

The SDLS series is available in a range from 35 to 150 Amps at 30 Vdc and is ignition protected and weatherproof. The switches are SAE J1625 approved for surface vehicles circuit breaker standards and SAE J1171 approved for marine circuit breaker standards. The SDLS series also meets 5000 amps at 12 Vdc for interrupt capacity per ABYC E-11, dc electrical systems of boats, Sensata said.

The new FDLS series is available in a surface mount version with a switchable manual reset. These FDLS units are also weatherproof; ignition protected and offered with the Klixon trip-free design. Sensata said it designed these circuit breakers with a stronger housing material for increased robustness and the ability to accommodate heavy gauge wire lugs across terminal studs.
