Description
EF65-56 Electronic Overload Relay
The EF65 is a self-supplied electronic overload relay, which means no extra external supply is needed. It offers reliable and fast protection for motors in the event of overload or phase failure. Easy to use like a thermal overload relay and compatible with standard motor applications, the electronic overload relay is convincing, above all, due to its wide setting range of 20 … 56 A, high accuracy, high operational temperature range (-25 … +70 °C operation), and the possibility to select a trip class (10E, 20E, 30E). Further features include temperature compensation, trip contact (NC), signal contact (NO), automatic- or manual reset selectable, trip-free mechanism, STOP- and Test function, and a trip indication. It is designed for 3 poles and connected directly to contactors with suitable types AF40, AF52, AF65. The product dimensions are width 7 cm, height 13.12 cm, depth 10.52 cm, and it weighs 0.821 kg.
Electrical ratings include rated operational voltage of Auxiliary Circuit 600 V AC/DC and Main Circuit 1000 V AC, rated operational current of 56 A, rated impulse withstand voltage of Auxiliary Circuit 6 kV and Main Circuit 8 kV, with insulation voltage of 1000 V. It has a degree of protection Housing IP20, Main Circuit Terminals IP10, and pollution degree 3. The product supports flexible and rigid connecting capacities with specified ranges for auxiliary and main circuits. Recommended tightening torque is 0.8 – 1.2 N·m for auxiliary circuits and 4 N·m for main circuits. The wire stripping lengths are 9 mm for auxiliary circuit and 20 mm for main circuit. Mounting position is from 1 to 6.
This overload relay complies with standards IEC/EN 60947-1, IEC/EN 60947-4-1, IEC/EN 60947-5-1, UL 60947-1, and UL 60947-4-1. It holds multiple certificates such as ABS, ATEX (for products produced from week 42, 2014), IECEx (for products from week 15, 2017), BV, CB, CCC, CCS, CQC, CE, UKCA, DNV, EAC, LR, RMRS, and UL certificates. Its customs tariff code is 85364900.
The package box dimensions are width 13.9 cm, height 10.7 cm, depth 7.55 cm, with a gross weight of 0.876 kg. The product is RoHS compliant following EU Directive 2011/65/EU and amendment 2015/863. Environmental friendliness is ensured by ABB EcoSolutions with waste to landfill validation (UL 2799 Zero Waste).
