The Sensata UPL1-28147-4 is a single-pole hydraulic magnetic circuit breaker featuring a lever actuator and panel mount design. This legacy product, part of the APL/UPL series, offers reliable circuit protection and power switching.
Designed for applications requiring precision operation, this circuit breaker functions similarly to an ON-OFF switch under normal load conditions. Upon detecting an overload, its internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. The 'trip-free' design ensures the internal contacts cannot remain closed during an overload, even if the handle is held in the ON position.
This model is recognized by UL per UL STD. 1077 as a supplementary protector and certified by CSA per CSA STD. C22.2–No. 235. It is suitable for industrial, military, and information processing applications where dependable circuit control is essential.
Key specifications include panel mounting, a lever actuator, and a single pole configuration. While specific current and voltage ratings are not detailed here, the APL/UPL line offers various configurations including series, shunt, and relay types with a choice of delays and ratings.
