Leviton Telcom 430MF5WLEV 30 Amp Mechanical Interlock

Product Description

The LEVITON TELCOM 430MF5WLEV is a 30-amp mechanical interlock designed to prevent two circuits or switching devices from being energized simultaneously. Mechanical interlocks provide a physical locking mechanism that enforces mutually exclusive operation between paired breakers, switches, or contactors. This type of hardware accessory is commonly used in transfer switch applications, generator hookups, and dual-feed panel configurations where accidental back-feed or simultaneous switching poses a safety hazard. Licensed electricians and panel technicians install this device as part of a compliant, code-appropriate power management setup.

The 430MF5WLEV is suited for use in residential and light commercial electrical panels where a mechanical means of interlock is required. Typical installations include manual transfer switch configurations for standby generators, dual-source panel arrangements, and service entrance equipment requiring enforced switching exclusivity. This hardware accessory unit is sold individually and is intended for use by qualified electrical professionals familiar with applicable NEC requirements for interlock installations.
