Hubbell HBLAC2 Auxiliary Contact No/nc Early Break

Product Description

The HUBBELL HBLAC2 is an auxiliary contact designed for use with switched enclosures in the Twist-Lock wiring device family. It features a NO/NC early break contact configuration rated at 600 volts, making it suitable for interlocking, monitoring, or control circuit applications where enclosure switching status needs to be signaled or logged. The part carries UL and CSA approvals and meets the UL 94V-0 flammability standard. Licensed electricians and industrial maintenance technicians typically install this accessory as part of a panelboard, motor control, or enclosed switching assembly.

The HBLAC2 is intended for switched enclosure applications within the Hubbell Twist-Lock product line. It is used where an auxiliary contact is required to report the open or closed status of an enclosure-mounted switching device. Typical installations include industrial control panels, motor starters, and similar enclosure-mounted switch assemblies in commercial and industrial settings. The early break configuration ensures the auxiliary contact opens before the main contact, which is critical for certain protective relay and interlock circuits.
