Applications
Non-fused 30 or 60 Ampere Motor Control Disconnect Switch“Suitable as Motor Disconnect” per NEC® 430.102(B) and 430.109(A)(6)
Arrow Hart’s new line of NEMA Type 4X disconnect switches are made from VALOX™ resin and are a flexible and economical solution
to 3-phase power switching applications. They are ideal for washdowns and corrosive environments where an OSHA lockout/tagout
disconnecting means is required. They are also suitable for use with metallic conduit and are available with auxiliary contacts for a
variety of control circuit applications.
