The integrated auxiliary switch changes state on trip, and the front- face "Tripped" message gives a clear visual indication that the relay has operated. The auxiliary contact ratings cover a wide voltage range: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, and 0.75 A at 690 V. These are the maximum switching capacities for the N/O and N/C contacts feeding the PLC input or the contactor hold-in circuit — derate for inductive DC loads per the standard DC-13 curve.
The footprint is 45 mm wide by 89 mm tall by 80 mm deep — a compact block that leaves room for adjacent devices in a crowded enclosure. Screw terminals accept 2× (0.5 to 1.5 mm²) solid or stranded, or 2× (0.75 to 2.5 mm²) with a ferrule. The screwdriver slot takes a PZ2 Pozidriv bit, 5 to 6 mm shaft diameter. Mounting position is any orientation; temperature compensation is active from -40 to +60 °C ambient.
The relay complies with substance restrictions per the RoHS directive, with a substance prohibitance date of October 1, 2009. The MTTF under high-demand-rate conditions is 2,280 years — a reliability figure that supports safety-related applications where the relay is part of a monitored protective circuit.
