APL1111-7086-6

The Sensata APL1111-7086-6 is a 4-pole hydraulic magnetic circuit breaker from the APL/UPL series. It is designed for reliable power switching, circuit protection, and control, functioning similarly to an ON-OFF switch under normal load conditions. Upon overload, the internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. This protector is 'trip free,' meaning it cannot be held closed during an overload.

Key specifications include a 4-pole configuration, lever actuator, and panel mounting. The APL/UPL series is recognized by UL and certified by CSA as supplementary protectors. This product is a legacy item and is no longer accepting new design-in orders. Sensata Technologies recommends the Airpax™ IAL series as an alternative for new designs.

Applications for this type of circuit protector include industrial, military, and information processing systems where precision operation is required. Its multi-pole assembly allows for linked handles and internally coupled trip mechanisms, ensuring all poles open simultaneously in case of a fault in any protected circuit. This makes it suitable for two-phase circuits, single-phase three-wire systems, or multiple related but isolated circuits.
