The EE Controls BN18F is a bimetallic thermal overload relay rated for 1.8–2.8 A, designed to protect single- and three-phase motors from overheating and sustained overcurrent conditions. It operates by sensing heat through a bimetallic strip and automatically tripping to disconnect power before motor windings are damaged. This unit is typically used in combination with a compatible contactor in motor starter assemblies across industrial, commercial, and HVAC applications. Confirm your contactor model and starter assembly with our team to ensure proper fitment.
The BN18F is designed to mount directly onto compatible EE Controls contactors as part of a motor starter assembly. Bimetallic overloads in this series are typically matched to a specific contactor frame size. Send us your contactor model number and we'll confirm compatibility before you order.
The BN18F has an adjustable current range of 1.8 to 2.8 A. This means the trip threshold can be set within that range to match the full-load amperage (FLA) of the motor being protected — helping ensure the overload trips accurately without nuisance tripping on normal start-up inrush.
EE Controls products can be difficult to source as the brand has limited North American distribution. Northern Breaker Group specializes in hard-to-find and obsolete electrical components. Contact our Calgary, Edmonton, or Vancouver locations and our team will check current stock or source the BN18F on your behalf.
