Can APM circuit breaker sealing boots be mounted on the outside of NEMA enclosures without compromising the enclosures’ integrity?
Yes. APM’s UL listed switch and circuit sealing boots represent an acceptable cost-effective solution where the user application requires external mounting of sealed electrical controls on NEMA type enclosures. They meet the requirements of UL Standard 50. NEMA enclosures for motor and other controls are typically found in machine shops and various metalworking environments that are often characterized by cutting fluids, lubricating oils and metal chips. NEMA enclosures which are used for outdoor applications benefit from our silicone cover material which is UV resistant. A wide range of lever, toggle, pushbutton and rocker style boots are offered for panel mounting.
