G Series

The G series is Otter Controls’ most versatile bimetal switch.

The G Series is available in a wide range of formats such as thermostat, safety cut-out or DC motor protector and in many permutations of temperature setting, current sensitivity, cover and sealing options.

The G series can be set to temperatures ranging from 5°C to 155°C (165°C for DC applications) with controlled differentials and tolerances from ± 2°C in both normally closed and normally open configurations. There is also a range of bimetal resistivities to adjust the current sensitivity to suit the application.

The G series strong snap action makes it suitable for both 12V & 24V DC motors and 240V AC applications. While it is larger than later generations of motor protector, through its versatility it maintains a strong position within the Otter range.
