This is a mechanical interlock accessory — it physically prevents the breaker from being switched ON until both locks are released, which is the standard arrangement for lockout/tagout (LOTO) compliance on a panel disconnect. The kit includes the adaptation hardware to mount onto the MTZ1 chassis; the keylocks themselves are Ronis type, a common European profile for industrial safety lock systems. ## Why two locks and one key matter for LOTO Two locks with identical keys means two separate padlocks must be removed before the breaker can leave OFF. That supports multi-worker isolation — each worker applies their own lock, and the last lock removed is the one that allows re-energization. The single-key-per-lock design (1 key per lock, same key for both) keeps the key captive in the lock while the breaker is OFF, so the key cannot be removed until the breaker is locked. This is a standard safety interlock pattern for MCC buckets and main disconnects where multiple maintenance crews share a single isolation point. ## What it fits — MTZ1 only, not MTZ2 or MTZ3 This kit is specific to the MasterPact MTZ1 frame. The MTZ1 is the smallest frame in the MasterPact MTZ family (up to 1600 A). The locking mechanism and adaptation plate are shaped to the MTZ1's front-panel cutout and handle geometry. It will not mount on MTZ2 or MTZ3 frames without modification — those frames use a different lock interface. If you are retrofitting an older MasterPact NW or NT breaker, this kit is not compatible; those frames use a different Ronis lock profile and a separate adapter part number. ## Installation note — Ronis key profile matters The keylocks are Ronis type, which is a specific keyway profile (not the same as Euro-profile or Abloy). If your facility already uses Ronis keyed locks on other disconnects, this kit can be ordered with the same key code to maintain a single-key-per-site policy. If you are starting fresh, the locks come keyed alike (both locks use the same key). The adaptation kit includes the mounting bracket and hardware; no drilling or cutting required on the MTZ1 escutcheon.","metaTitle":"Schneider LV847522 MasterPact MTZ1 Ronis Keylock Kit, 2 Lock","metaDescription":"LV847522 OFF-position locking kit for MasterPact MTZ1 circuit breakers. 2 Ronis keylocks, 1 key, adaptation kit included.

Availability and current pricing are confirmed at quote time. For volume or blanket-order pricing, submit a formal RFQ with your annual usage estimate."},{"question":"What is the closest alternative to LV847522 in the MasterPact accessory family?","answer":"The closest alternative is the LV847521, which is the same OFF-position locking kit but with a single Ronis keylock instead of two. If your LOTO procedure requires only one worker to lock out the breaker, the single-lock version saves cost. For multi-worker isolation, the two-lock LV847522 is the correct choice."},{"question":"What is LV847522's listed range on this component line?","answer":"The LV847522 belongs to the MasterPact range from Schneider Electric, specifically the MTZ1 frame accessory line. It is a locking accessory for circuit breakers and switch disconnectors."},{"question":"What compliance documentation does this brand provide for LV847522?","answer":"Schneider Electric provides RoHS and REACH compliance declarations for the LV847522 as standard. The MasterPact MTZ1 platform carries IEC 60947-2 certification. Specific UL or CSA documentation depends on the breaker configuration the kit is installed on; the accessory itself does not carry a separate UL listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LV847522","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/LV847522 when reusing this data.
