The EX9R38B18A Noark Bimetallic Overload Relay offers reliable protection for your electrical systems, accommodating a current range of 12 – 18A. Designed for optimal performance, this overload relay enhances safety by preventing overheating and prolonging equipment life. Trust in its robust construction for superior reliability in industrial applications.
The EX9R38B18A is designed for direct plug-on mounting with Noark EX9C series contactors in the B38 frame size. If you are unsure whether your existing contactor is compatible, send us your contactor part number and we'll confirm the fit before you order.
This relay features an adjustable dial covering the 12–18 A range. You should set the dial to match the full-load current (FLA) rating shown on your motor's nameplate. For Canadian installations, always verify the setting complies with CSA C22.1 (Canadian Electrical Code) motor protection requirements for your specific application.
Noark EX9R series overload relays can be difficult to source through standard electrical distributors.
