It provides phase failure sensitivity, tripping at 130 % of Ir on two phases with the third at zero, and includes a 1 NO + 1 NC auxiliary contact configuration. Rated operational voltage is 690 V AC 0...400 Hz for the power circuit, with a rated insulation voltage of 690 V conforming to IEC 60947-4-1. The 7...10 A adjustment range sets the motor full-load current window this relay protects — sized for a motor drawing between those amps at full load, with the Class 10A curve allowing the motor to start without nuisance tripping on moderate overloads. Ambient temperature compensation from -40...60 °C without derating means it holds its trip accuracy across cold warehouses and hot machine enclosures alike, per IEC 60947-4-1. The IP20 degree of protection means it is finger-safe but not sealed — intended for installation inside a control panel or enclosure, not in washdown or outdoor locations. Conforms to EN/IEC 60947-4-1 for motor-starter coordination, EN/IEC 60947-5-1 for control-circuit devices, and EN 45545 for railway fire safety. Rated insulation voltage also carries CSA and UL ratings at 600 V, and the dielectric strength is tested at 1.89 kV at 50 Hz conforming to IEC 60947-1. Flame retardance rated V1 conforming to UL 94.","metaTitle":"TeSys LRD14S207 thermal overload relay, 7-10 A, Class 10A, o","metaDescription":"Obsolete TeSys Deca LRD14S207 differential thermal overload relay, 7-10 A adjustment range, Class 10A, EN/IEC 60947-4-1.
