DV7AM Series



The Model DV7AM Series is an excessive current automatic resetting, snap action bimetallic protector. They provide both thermal and current overload protection for use as a thermal protector or thermostat in a wide variety of applications. The core technology behind these controls is a prestressed, bimetallic blade that provides snap-action for greater contact life and increased reliability. The DV7AM-SH combines the precision switch capabilities along with a self-holding feature. The Self-Hold feature, once activated under fault condition, maintains its open state of contacts until power is removed. There is no reset buton to access so simply removing power and allowing to cool will reset the device. This design feature is classified as a manual reset device under strict Safety Agency guidelines. It is a cost effective, well engineered design that provides exceptional protection and is considered to be the ultimate safety device with proven protection.
