MQ165 3Interlock 1Reset 1Latching 5 Keys Switch 250VAC 4A for Kitchen Hood is a safety interlock switch designed for hood systems. It combines multiple interlock stages with a reset and a latching action, controlled through five keys, to help ensure safe and controlled operation of kitchen hood equipment. Key benefits Enhanced safety: multiple interlocks reduce the risk of unintended startup and ensure the hood operates only under safe conditions. Resettable and latched control: after maintenance or access, a manual reset and the latching action help prevent accidental restart. Multikey access: the five keys provide flexible control and authorization options, supporting configurable operator access. Suitable electrical rating: 250 VAC, 4 A makes it compatible with common hood control circuits and typical restaurant or commercial kitchen loads. Simple integration: designed to fit standard hood control applications where an interlock, reset, and latch are required. Key attributes Model: MQ165 Interlock configuration: 3Interlock Reset: 1 Reset Latching: 1 Latching Keys: 5 Keys Electrical rating: 250 VAC, 4 A Application: for Kitchen Hood Size and material: not specified in the listing; dimensions and construction details are not provided here Performance and compatibility Electrical performance is rated for 250 VAC at up to 4 A, suitable for common hood control circuits. The 3interlock, plus 1 reset and 1latching configuration offers a structured sequence for safe hood operation and service workflows. Intended for kitchen hood installations, with emphasis on safety interlock behavior and controlled reactivation after service. Use cases and applications Commercial kitchen hood safety interlock: install to ensure hood operation only when all interlock conditions are met, reducing risk during maintenance or door/panel access. Maintenance and service workflows: after servicing hood components, a reset is required to reenable operation, with the latch preventing immediate restart until proper reset. Multioperator environments: five keys allow distributed authorization, supporting scenarios where multiple staff or technicians require controlled access to hood operations.
