Application

The EE Controls BN18N Bimetallic Overload Relay is rated for a current range of 15–23 A, making it well-suited for protecting three-phase and single-phase electric motors in industrial motor control circuits. Its bimetallic tripping mechanism provides reliable, temperature-compensated overload detection, guarding motors against sustained overcurrent and overheating damage. This relay is typically used in combination with a compatible contactor in an MCS (motor control starter) assembly. If you need help confirming compatibility with your existing contactor or starter, send us your equipment details and we'll confirm the fit.

The BN18N is adjustable across a range of 15–23 A. To select the correct setting, match the relay's dial to your motor's Full Load Amperage (FLA) as listed on the motor nameplate. The FLA should fall within the 15–23 A range; if your motor draws more or less, a different EE Controls overload model would be required.

Northern Breaker Group specializes in obsolete and hard-to-find electrical components. If the BN18N is no longer in regular production, we maintain access to surplus and legacy stock. Contact our Calgary, Edmonton, or Vancouver counters for current availability, or request a quote online and our team will source it for you.

Bimetallic overload relays are not universally interchangeable — mounting footprint, contactor interface, and reset-mechanism style must all match. Before substituting the BN18N for another brand's relay, verify that the physical mounting and electrical connections are compatible with your contactor. Send us your existing starter or contactor model number and we'll help confirm whether the BN18N is a suitable replacement.
