It mounts directly onto WEG CWB9 through CWB38 IEC contactors (9–38 A frame) or can be panel-mounted with a separate-mounting kit, making it the standard overload for building your own motor starter. Each model covers a specific, infinitely adjustable trip-current band — select the band that brackets your motor's full-load amps (FLA).\u003c\/p\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2-pole bi-metallic thermal overload relay\u003c\/li\u003e\n\u003cli\u003eTrip Class 10 (trips within set time at 1.5× the dial setting)\u003c\/li\u003e\n\u003cli\u003eInfinitely adjustable current dial — set to the motor FLA\u003c\/li\u003e\n\u003cli\u003ePhase-loss \/ phase-unbalance sensitivity\u003c\/li\u003e\n\u003cli\u003eAmbient temperature compensation, approx. -13°F to +140°F (-25°C to +60°C)\u003c\/li\u003e\n\u003cli\u003eSelectable Manual \/ Automatic reset, with TEST and STOP functions\u003c\/li\u003e\n\u003cli\u003eIsolated auxiliary contacts: 1 N.O. + 1 N.C.\u003c\/li\u003e\n\u003cli\u003eRated insulation voltage 690 V (IEC 60947), 600 V (UL\/CSA)\u003c\/li\u003e\n\u003cli\u003eOperating frequency 50\/60 Hz (rated up to 400 Hz)\u003c\/li\u003e\n\u003cli\u003eDirect mount to WEG CWB9–CWB38 contactors (9–38 A)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cp\u003eUsed in motor-starter and control-panel builds protecting pumps, fans, compressors, conveyors, and general-purpose AC motors where reliable overload and single-phasing protection is required.\u003c\/p\u003e\n\u003cp\u003ePair the WEG RW27-2D2 Class 10 thermal overload relay with a matching WEG CWB-series contactor to build a compact, code-compliant motor starter.
